Evaluation and Implementation of Future Water Supplies for Tampa Bay Water Tampa Bay Water (agency) is a regional, wholesale water utility. A special district of the state of Florida, the agency has an unequivocal obligation to provide drinking water to 2.5 million people through its member governments: Pasco, Pinellas, and Hillsborough counties, and the cities of New Port Richey, St. Petersburg, and Tampa.

Master Water Plan Development The agency updates its long-term master water plan every five years as required by its governing documents. The last version of the plan was approved by the agency’s board of directors in December 2018; the 2023 plan update is now underway. The plan, which has a 20-year horizon, inventories existing supply facilities and distribution systems, forecasts future drinking water demands, explores potential water savings through demand management, inventories existing and future regulations related to permitting, inventories and updates source water assessment and protection efforts, and evaluates potential new supply projects through feasibility studies. The plan thus ensures that the agency meets the needs of its members proactively and in an environmentally sustainable and fiscally responsible manner. Planning for regional water supplies presents several challenges. The first challenge is determining the quantity and timing of new drinking water supply. The agency’s regional system sprawls over 600 miles and delivers supplies from diverse sources, such as groundwater, surface water, and desalinated water. In addition, the agency owns a 15.5billion-gallon capacity off-stream reservoir. The overall system is heavily influenced by several factors, including climate variability, climate change, sea level rise, El Niño/La Niña phenomena, and water quality. Determining the right time and location for new water supply is crucial; bringing new supplies online too soon may result in distribution water quality issues and unitary rate increases. By incorporating robust demand forecast modeling into the plan, the agency evaluates different demand and supply scenarios so that it can adapt to different levels of uncertainty with respect to future demands and future climate outlook.

The plan also incorporates the agency’s water shortage mitigation plan. If adopted by the regional water management district, the plan could postpone the need for new supply in the short term so as to avoid building new supply to address extended droughts. Additionally, the plan includes strategies for conservation and demand management that, if implemented by the agency’s members, could produce significant savings over the planning horizon and equally postpone the need for new supply, thus avoiding upfront capital expenditures, as well as operating costs. Based on current projections, the Tampa Bay region will need an additional 10 million gallons of drinking water by 2028, and another 10 million by 2040. Some areas within the region, however, are experiencing varying levels of growth; south Hillsborough County, for example, is experiencing an influx of population at a faster rate than other areas. As a result, the county will need additional supply capacity by 2025. Although the agency has enough supply to meet all current needs of the county, the system constraints are such that a new conduit to deliver existing supplies must be built by 2025. The plan evaluated several options to address this problem, either by constructing a pipeline from the agency’s regional treatment plant to south Hillsborough County, or by developing a new groundwater supply in the south county area. The new groundwater supply concept relies on the county’s recharge of salinity barrier wells, known as the South Hillsborough County Aquifer Recharge

Project (SHARP), which, if successful, will generate water use credits that could be used to permit a new groundwater treatment plant through the regional water management district. The plan evaluates several potential water supply project concepts that could meet future needs. These concepts include potable reuse and developing new groundwater supply, as well as expanding existing surface supply. In addition, the agency approved its demand management plan that, if successfully implemented, could postpone the need for new water supply sources. Through the demand management plan, the agency could save 11 million gallons per day (mgd) by 2040, effectively postponing building any new supply. The water supply project concepts were evaluated for their environmental sustainability, reliability, and cost. Over the course of four years, the agency explored the feasibility of these concepts to determine which can be configured to provide a total of 20 mgd by 2035, while at the same time preserving the ability to phase construction of the supply project. Phasing the project would prevent overbuilding the supply capacity, which could have negative operational and maintenance effects. The agency worked with its member governments through a collaborative group, and through the feasibility evaluation process, agency staff and its member governments were able to narrow the list of potential project configurations that could meet future regional demand. Preliminary feasibility studies were completed and presented to the agency board, which approved three potential new water supply projects: S Groundwater wellfield and treatment plant via net benefit from SHARP S Regional surface water treatment plant expansion S Desalination plant expansion The new groundwater wellfield and treatment plant via net benefit from the SHARP project is being evaluated as both a potential solution to the hydraulically constrained south Hillsborough County and as Continued on page 6

Continued from page 4 a new water supply project that can be phased in. The county is moving forward with the SHARP project, which will eventually consist of injecting 12 million gallons (MG) of treated wastewater into the nonpotable zone of the aquifer in the coastal area of the south county. The main purpose of the SHARP project is to provide a salinity barrier and minimize salt water intrusion into the fresh water aquifer. As a result of this project, the agency could obtain water use credits from the regional water management district to develop a new groundwater supply further inland from the SHARP site. Initially, this project could provide up to 7.5 MG of drinking water per day, which would satisfy the most-immediate south county need for additional capacity, as well as provide some regional benefit. The SHARP project could also be expanded by injecting additional quantities of treated wastewater, either from the county facility or from neighboring City of Tampa wastewater facility. This expansion would address the additional regional demands that need to be met by 2040.

Plan Approval and Recommendations The approval of the plan authorized the agency to proceed with an in-depth feasibility study on the potential new supply projects. The goal of the study is to determine which of the three projects can provide the most reliable and sustainable yield so that the additional 20 mgd could be supplied to the region by 2040. The agency will continue with these studies over the course of several years, while

simultaneously working on a solution to supply south Hillsborough County with additional capacity by 2025. As a part of the detailed study, these projects will be incorporated into the agency’s optimized regional operations plan (OROP) to determine how the newly incorporated supply would affect the reliability of the existing system and identify specific constraints that could be alleviated to optimize new supply. The surface water plant and desalination plant projects will evaluate expanding the facilities. The desalination plant would need to be optimized before being expanded; this will be the focus of the future feasibility study over the next several years. The surface water plant will also be evaluated for optimization and expansion. The agency will evaluate the ability to harness additional quantities of water from the Alafia River, on which it currently relies. Parallel to the feasibility study, the agency will proceed with the implementation of the demand management plan. By working with the member governments, the agency will assist them with implementing specific programs identified in the plan. If these programs are implemented, the region could save 11 MG per day of drinking water supply over the next 20 years. If these savings are realized, the agency may postpone constructing new supply projects beyond what is currently forecast. Along with the feasibility study and demand management, the agency is undergoing an effort to better understand the nexus between financial decisions and water supply decisions so that the sequencing of water supply development can be implemented in an appropriate time frame.

This effort will contribute to the overall feasibility effort; the results of the sequencing study will inform the decision on new supply development. Before determining which project is the most feasible for further implementation, the agency will undergo optimization of existing facilities. The regional surface water treatment plant and desalination plant have been identified as two facilities that could be optimized and made more reliable, and there is a potential to obtain additional yield from the surface water plant. The goal of the optimization is to make the overall system more reliable and capture the maximum yield possible before either of the two facilities is expanded. Another important factor that could affect the timing and quantity of new supply is the Tampa Augmentation Project (TAP) from the City of Tampa. A member government of the agency, the city is the only member that owns and operates its water supply and relies on the agency to provide additional quantities of water during dry times. The city relies on the Hillsborough River and can withdraw up to 82 MG of water a day through its Dave L. Tippin Drinking Treatment Facility. The city is evaluating a potential potable reuse project concept; currently, its wastewater treatment plant discharges upwards of 50 MG per day of treated wastewater into the Hillsborough Bay. The TAP is an indirect potable reuse project that evaluates injecting up to 50 MG of wastewater into the nonpotable zone of the aquifer and withdrawing a certain quantity, either at the natural Hillsborough River reservoir or at the head of the city’s water treatment plant. Currently, the agency and the city are working through institutional aspects of this project. If the city’s project is deemed feasible and permittable, the overall regional demand the agency would need to meet would be decreased. This could result in postponing the need for new supply beyond the 2040 planning horizon. The 2023 long-term master water plan will incorporate all the described efforts that will ultimately answer the question of how much additional drinking water is needed for the region and when new supply needs to be built. Throughout this process, the agency will involve the public, community stakeholders, and elected officials as these efforts move forward. The plan will be presented to the board in December 2023 for approval, which will continue the agency’s long-term water supply planning efforts.

Regional Approach to Alternative Water Supply Planning and Funding is a Win-Win for Central Florida Stakeholders Scott Manahan, Mary Fickert Thomas, Gene Heath, and Ryan Taylor he concept of taking a regional approach to water supply planning is not new in central Florida. The utilities in Polk County, in collaboration with the Southwest Florida Water Management District (SWFWMD), prepared a countywide regional water supply plan in 2009. The Central Florida Water Initiative (CFWI) came about in 2011, which was jointly developed by the three water management districts that have jurisdiction in the central Florida region: St. Johns River Water Management District (SJRWMD), South Florida Water Management District (SFWMD), and SWFWMD. It was determined in 2015 that approximately 1,100 mil gal per day (mgd) of water supply would be needed in the fivecounty region in 2035, while the sustainable supply from the Upper Floridan aquifer (UFA) is only about 850 mgd, leaving a large deficit. The heavily populated areas of central Florida have nearly reached their limits of permittable, traditional, fresh groundwater, and utilities are now forced, out of necessity, to seek alternative sources of water to meet growing demands. Other water supplies, including brackish water pumpage from the Lower Floridan aquifer (LFA), will need to be developed to help meet the shortfall in demand. The Polk Regional Water Cooperative (PRWC) was formed in 2016 by 16 local government members (15 cities and Polk County), as shown in Figure 1, with the intention of proactively developing a large, regional water supply system to provide additional capacity to the participating members. Public water supply demand projections developed during 2018 in Polk County showed a need of approximately 109 mgd by 2040. The sustainable yield of the UFA, which is the current source of water supply, is estimated to be 72 mgd. The deficit of 37 mgd will need to be met by an alternative water supply (AWS). The PRWC identified over 200 potential water supply projects, and three were selected for implementation. Two of the projects will ultimately involve large-capacity wellfields that

T

will supply raw water from the LFA to reverse osmosis (RO) treatment facilities at the West Polk and Southeast plant sites: The Southeast plant will have a design capacity of 30 mgd, whereas the West Polk plant is estimated to generate up to 15 mgd of new water supply. A third project, called the Peace Creek Integrated Water Supply Plan (IWSP), seeks to increase available water supply from the UFA by using innovative surface water capture and aquifer recharge methods. The initial phase of work required to implement the new water supply projects included feasibility studies to estimate the yield of each project and to collect the data required for preliminary design of the facilities. The cost to conduct the phase I work, which includes test drilling, groundwater modeling, water quality sampling, and other hydrologic analyses, is $23 million. Funding is being provided by SWFWMD (50 percent share), while the remaining costs will be provided by the member governments, State Revolving Fund (SRF), and other grants or loans from the CFWI and private financial institutions.

Alternate Water Supply Options and Funding The key to the successful implementation of the project is willing participation and clear communication through contracts among the various stakeholders who have a vested interest in the outcome of the project. Having viable, alternative water resources to meet the needs of this growing region is vital to the economy and people who call central Florida home. The collaborative effort of the PRWC members represents a positive change in organizational dynamics and an innovative approach to funding large-scale water supply projects, and brings attention to a region with sensitive natural resources. Rapid population growth in central Florida has greatly stressed its primary water source, the UFA. The population of Polk County for example is projected to increase from an estimated 592,082 in 2015 to 789,760 in 2035 (CFWI, 2015). A

number of south Florida utilities have turned to RO desalination of brackish groundwater as their primary AWS because hydrogeologic conditions in the region are favorable for the implementation of this technology. Abundant brackish groundwater resources are available in the aquifer systems, and an extraordinarily transmissive injection zone, the so-called “Boulder Zone” of the LFA, is present and can be used to efficiently and economically dispose of the desalination concentrate. The Florida Department of Environmental Protection (FDEP) promotes the use of AWS and estimates that 70 percent of additional public water supplies developed in the state by 2035 will entail AWS development (Regional Water Supply Planning Annual Report, 2016). The AWS options in central Florida are more limited because of its inland location and local hydrogeological conditions. Brackish groundwater development in central Florida has been much more limited to date than in south Florida because brackish groundwater resources that are hydraulically isolated from the overlying freshwater UFA occur at relatively great depths (and are thus more expensive to utilize) and potential injection zones are less well-developed than in areas further to the south. The cost to develop and treat brackish groundwater supplies can be 50 to100 percent greater than conventional freshwater sources because the supply wells are deeper, the RO treatment process utilizes more energy, and there are costs associated with concentrate disposal (injection wells). As a result, it would be difficult for a small utility to construct, operate, and maintain a brackish RO plant. A significant economy of scale is realized by constructing large, regional water treatment


facilities as opposed to smaller, local plants. The SFWMD regional water supply plan reported an estimated cost of $2.65/1000 gal for brackish water supply from a hypothetical 15-mgd plant that increases to $5.81/1000 gal from a similar 3mgd plant (SFWMD, 2016). The concept of PRWC is to join several utilities together that have common water supply needs, with the goal being the development of a reliable, economical, and sustainable large-scale public water supply to serve the growing population. Examples of funding initiatives that the PRWC has seen as successful include: S The SWFWMD is providing a 50 percent share of the funding for the $23 million feasibility study underway for the three PRWC projects. The district promotes these regional water supply efforts to use AWS, as it reduces stress on traditional groundwater sources and consolidates the withdrawals so that numerous entities are not vying for the resource, which complicates permitting efforts. An added benefit to collaborating with these agencies is that, for example, through these projects, SWFWMD has brought additional technical resources and improved regulatory processes. S The PRWC has secured low-interest SRF loans for the projects, which has eased much of the burden on small municipalities to generate the funds needed to maintain cash flow. S The PRWC members joined forces to draft the Heartland Headwaters Protection and Sustainability Act, which was adopted by the Florida Legislature in 2017 and statutorily

recognizes the vital importance of the region’s water resources to Polk County and the surrounding regions. It declared that fostering partnerships between regional water supply authorities is in the state’s interest and it facilitates state funding support. The goal of this effort was to bring more attention to Polk County, and there has been some success in allocating additional funding in the 2019 legislative session that is currently underway. S The PRWC was recently invited by the U.S. Environmental Protection Agency to apply for a low-interest and flexible Water Infrastructure Financing and Innovation Act loan. Full-scale implementation of the three PRWC projects are expected to cost over $600 million to construct, so it’s clear that a group effort is required, given the magnitude of the undertaking. Test drilling at the proposed Southeast and West Polk wellfield locations was initiated during spring 2018 and work has also been conducted at two sites as part of the Peace Creek IWSP. An update on the status of these projects follows.

Test Drilling Updates: Southeast and West Polk Water Treatment Plant Wellfields Locations of the West Polk and Southeast wellfield sites are show in Figure 2. Limited existing data are available on the hydrogeology of the LFA in Polk County, and central Florida

in general. A southeast deep exploratory well (SE-DEW) program was completed near the southern end of the proposed southeast water treatment plant (WTP) wellfield in 2010 (PBS&J, 2010). Pumpage from a wellfield consisting of 15 brackish water LFA supply wells was permitted in 2014 by SFWMD, with a combined withdrawal rate of 37.5 mgd. The proposed southeast WTP production wells will be located along Boy Scout Camp Road between CR-630 and FL-60. A deep LFA southeast test production well (SE-TPW), LFA monitoring well (SE-LFA), UFA monitoring well, and water table aquifer monitoring well were constructed and tested near the north end of the proposed wellfield alignment. The test program began during spring 2018 and included water quality sampling, geophysical logging, packer testing, a long-term aquifer performance test, and lithologic analyses. Testing was completed during March 2019. The production interval of the supply wells occurs between the approximate depths of 1,400 and 1,900 ft. Potential injection zones for concentrate disposal may be present below 2,300 ft at the WTP site. The brackish water source has total dissolved solids (TDS) that vary from approximately 1,200 to 3,000 mg/l and well yields may vary from 2 to 2.5 mgd. The conceptual plan for the SE-WTP is to obtain raw water from the upper part of the LFA (Zone I) and inject the RO concentrate Continued on page 18

Continued from page 17 into a deeper zone. Figure 3 shows the general stratigraphy of the site and the approximate well depths. The WTP and deep injection well system are planned to be located at the north end of the wellfield alignment. Drilling at the West Polk site (Figure 4) began during spring 2018 and was completed in November 2019. A surficial aquifer monitor well, UFA monitor well, dual-zone monitor well, and test/production well were completed at the Lakeland site. Aquifer performance testing, geophysical logging, and water quality sampling were also completed during 2019. The supply wells at the West Polk site are anticipated to be deep, with Fiberglass casings

set to approximately 1,900 ft below land surface and total depths of roughly 2,200 ft.

Peace Creek Integrated Water Supply Plan Update The purpose of the study is to determine if seasonally available excess surface water can be stored or used for aquifer recharge and wetland rehydration to potentially offset the impacts of freshwater pumpage from wellfields in Polk County. The project involves site evaluations, data collection, modeling, permitting, and data analyses to determine if an IWSP is feasible. Site evaluations were initiated in early 2019 and are currently underway at several locations.

Geotechnical data, including standard penetration test (SPT) borings, slug tests, and water-level monitoring were conducted at two of the sites to assess the potential for storing water and aquifer recharge. The amount of water that may be available for recharge has been estimated with computer model simulations. Currently, the team is pursuing conceptual design alternatives for water use and environmental resource permitting efforts that will be conducted in 2020, assuming favorable results are achieved during the site evaluations.

Conclusions Large-scale water supply offers inherent benefits via economies of scale and regional water supply plans are looked upon favorably by regulators and funding sources. The PRWC has undertaken a focused approach to addressing water supply needs in Polk County with the evaluation of two large water supply wellfields and an innovative plan to increase water storage, wetland restoration, and aquifer recharge. The three projects currently being evaluated are estimated to provide in excess of 45 mgd of public water supply. With construction costs estimated to be over $600 million to implement these projects, a cooperative approach among the utilities, regulators, and other stakeholders is essential to the success of the program.

On Tuesday, the AWWA Diversity and Member Inclusion Committee, led by Jackie Torbert, committee chair and past FSAWWA chair, and the FSAWWA Young Professionals Committee held a workshop for STEAM (science, technology, engineering, art/architecture, and math) students from the Odyssey Middle School. The program included presentations from the local high school students, a demonstration of robot designs, lunch, and a scavenger hunt in the exhibit hall.

At left: Students at the scavenger hunt. Below: High school students during the discussion session.

High School Academy Students Meet, Greet, and Eat For the fourth year, the FSAWWA Operators/Maintenance Council invited high school students from Heritage High School Academy of Environmental Water and St. Johns Technical High School Academy of Coastal and Water Resources to attend the conference. It’s predicted that over 30 percent of the water industry’s operators will be retiring in the next decade and there is already a shortage of new operators to fill their shoes. The section is taking proactive measures to overcome this shortage through the FSAWWA Operators Initiative. The goals of the initiative are to: S Understand and communicate the need for operators S Support the development of new and existing operators As part of this initiative, FSAWWA provides support to two technical high schools in Florida that provide four years of coursework and training in preparation for students to take the Class C license operator exam. The students attended the conference on Tuesday, December 10. As part of their schedule for the day, they attended a lunch that included a panel Continued on page 22

FWEA FOCUS

Can You Take Charge of Your Professional Development? Michael W. Sweeney, Ph.D. President, FWEA ost of us by now have an understanding of what asset management means in the context of water infrastructure and utility management. It was “imported” to our sector almost twenty years ago courtesy of primarily Australia, New Zealand,

M

and the United Kingdom. These nations’ utilities underwent a restructuring to become more financially transparent, to facilitate longer-range planning, and to justify their rates to maintain an acceptable level of service. As the principles and practices of asset management have become more familiar to us over the years, many utilities here in the United States asserted that they were already “doing AM” and have all of the “requisite” master plans, projects, and rate studies to prove it. Other utilities have perceived a functioning asset management program as grounded in a

technological pursuit involving such things as a computerized maintenance management system (CMMS), geographic information systems (GIS), and customer information systems (CIS). In reality, both points of view have validity. Boil it all down, and asset management is a decision support process based on continuously refining and executing operations, with maintenance efforts and investment strategies to ensure that desired levels of service and sustainability are achieved. The key to utilities possessing a viable asset management program is to focus on the various essential competency elements as embodied in five questions: 1. What is the current state of my assets? 2. What is my required "sustainable" level of service? 3. Which assets are critical to sustained performance? 4. What are my minimum life cycle costs? 5. What is my best long-term funding strategy? Here is something interesting. According to a U.S. Environmental Protection Agency report (EPA 800-F-19-002, February 2019), as of 2018 about 15 states now require some level of asset management planning, even affecting systems serving as few as five hundred people. So why bring up the subject of asset management? Well, it’s budget preparation time for many of us and it’s important to give some thought to starting or improving your programs and updating your answers to those five questions. For me, the answer to the question contained in the title of this column is “yes.” It may be sort of a de facto standard or best practice, but the trend is clear and the bar is rising. We cannot continue to assume we know or have the information needed to determine the condition of all our critical assets. “Assumptions” live in the land near where you don’t know what you don’t know. We as operators, engineers, or managers know the dangers of this realm and the need to chart a course with facts and data that more than justify the necessary future investments to avoid asset failure or noncompliance. When it comes to asset management, even though the principles and practices have been with us awhile, practicing and refining our decision making is where order comes from chaos and where water quality and service are reliability delivered.

Purified Water Production: A Research and Development Plant Operator’s Perspective Anna Ness, Ryan Popko, Greg Wetterau, and David Prah Introduction and Background Interest in water reuse technologies has been growing in recent years as the demand for potable water approaches the limit of conventional water supplies. In northeast Florida, the Floridan aquifer is the primary water supply for nearly 337,000 residents of the greater Jacksonville area, served by JEA. It’s anticipated by JEA that potable water demands will continue to increase, necessitating consideration of alternative and sustainable water supplies. As a result, JEA has taken a proactive approach by launching a water purification program to evaluate potable reuse as an alternative water supply. The water purification program includes research and development (R&D) testing, demonstration, and planned full-scale implementation. The primary objective of the R&D phase of the program was to collect trusted technical data through rigorous pilot testing to observe and compare process performance and purified water quality of the two industryleading treatment trains for potable reuse.

This article describes the daily operations and maintenance (O&M) activities, water quality testing protocol, equipment troubleshooting, and lessons learned during R&D testing. Operational performance and water quality results are not the focus here and have been presented in other papers and articles on the R&D testing portion of the project. The JEA R&D testing was the first in Florida evaluating the two leading treatment trains side by side with two drastically different source waters. One source water was from a more traditional municipal water reclamation facility (WRF) primarily consisting of residential customers and the other was from a WRF with significant industrial sources in the collection system. As a result, JEA gained a better understanding of each treatment train’s robustness by observing how the leading treatment trains performed over these widely varying conditions. The first train was equipped with ultrafiltration (UF) followed by low-pressure reverse osmosis (LPRO) and an advanced oxidation process (AOP), or UF-LPRO-AOP.

Figure 1. Research and development was conducted for two different water purification process systems.

Anna Ness is an environmental engineer and David Prah, P.E., BCEE, is a principal with CDM Smith in Jacksonville. Ryan Popko, P.E., is a consulting engineer with JEA in Jacksonville. Greg Wetterau, P.E, BCEE, is vice president with CDM Smith in Rancho Cucamonga, Calif.

The second train included flocculationsedimentation, then ozonation, followed by biologically active filtration (BAF) and AOP, or Ozone-BAF-AOP. Figure 1 presents a process flow diagram depicting both treatment trains. To provide a true side-by-side comparison, these two systems were operated in parallel at the two different JEA WRFs for approximately five months each. The next step in the water purification program will utilize the treatment train selected from the results of the R&D testing and implement this treatment approach for a demonstration facility with a treatment capacity up to 1 mil gal per day (mgd). The purpose of the demonstration facility will be to showcase the advanced water purification technologies, while amassing a considerable foundation of trusted technical data. Water quality data are essential for demonstrating the safety of the purified water to the public and to regulators. Operational data from the demonstration facility will also inform a more-efficient design for a full-scale facility. The demonstration facility will be fully expandable to full-scale implementation, which for planning purposes is approximately 10 mgd of purified water. The actual capacity of the full-scale facility will depend on the future need for the purified water. Contracting with CDM Smith, JEA began a “turn-key” program for the R&D testing where, working collaboratively with JEA, CDM Smith selected and procured the equipment, developed the R&D testing and safety protocol, provided all O&M services, and prepared all applicable reports. The R&D plant was operated continuously and members of the consultant team were onsite daily.


Figure 2. During start-up of the UF-RO system, new RO elements were installed, as well as an inline total organic carbon (TOC) analyzer. Inline TOC analyzers are not widely used, and this innovative instrument helped operators monitor treatment performance in real time.

Research and Development Testing Objectives While the focus of this article is specifically on R&D plant operations, the overall primary objectives of the R&D testing were as follows: S Characterize the secondary treated clarified effluent, prior to ultraviolet (UV) disinfection, at the Buckman and Southwest WRFs. This water was used as the source water for the R&D treatment trains. S Identify a single-treatment process train system (either UF-LPRO-AOP or OzoneBAF-AOP) for subsequent demonstration and implementation. This determination would be based on treatment performance, capital and O&M costs, waste management, ease of permitting, and reliability/robustness. S Determine appropriate design criteria and operational parameters for the demonstration facility in order to develop a building layout, capital cost estimate, and O&M cost estimate for the demonstration facility. S Develop a comprehensive public outreach plan to clearly explain the treatment processes and safeguards for public health, and provide consistent, readily available information to the community.

Research and Development Plant Equipment This section provides information related to the R&D test equipment employed at the Southwest and Buckman WRFs. The R&D equipment for the two treatment alternatives was procured from various vendors, and the selection was generally made using performance-based

specifications. Another criteria for equipment selection was treatment flexibility, not only for varying source water quality, but also for additional variables that are stated, which helped provide detailed costs and a clear direction for demonstration testing. The following subsections provide general information related to the water purification equipment utilized throughout the R&D testing. Ultrafiltration and Low-Pressure Reverse Osmosis The UF system served as the first unit process within the UF-LPRO-AOP system and consisted of the Spectrum Ultrafiltration Pilot Plant as manufactured by Wigen Water Technologies. The UF process consisted of two parallel UF modules. Following the UF process, the UF filtrate was combined into an equalization tank and conveyed to the LPRO system for further purification. A photo of the LPRO system is shown in Figure 2 (the photo was taken during start-up when the elements were being installed). This system, also provided by Wigen Water Technologies, was configured in a 2:2:1:1 array with a total of eighteen 4-in.diameter elements. Individual process variables evaluated as part of R&D testing for the UFLPRO process included a UF module manufacturer, UF flux rate, and LPRO flux rate. Ozonation and Biologically Active Filtration A pretreatment step, consisting of a coagulation, flocculation, and sedimentation system, was used prior to the Ozone-BAF-AOP system. Following sedimentation, settled water

was conveyed to the ozonation system for further purification; following the ozonation process, ozonated water was conveyed to the BAF system. Three different media types and two different column configurations were evaluated in the R&D testing. A picture taken inside the Ozone-BAF system (manufactured by Intuitech Inc.) is shown in Figure 3. Individual process variables evaluated during R&D testing of the Ozone-BAF process included coagulation conditions (i.e., coagulant type, dose, settled water pH), sedimentation basin overflow rate, ozone dose-to-TOC ratio, BAF media type (anthracite, spent GAC, virgin GAC), BAF media configuration (parallel versus series), BAF surface loading rate, and empty bed contact time. Advanced Oxidation A common advanced oxidation system served as the final unit process for both processes. This system was manufactured by SUEZ. The UV dose, oxidant dose, and oxidant type (sodium hypochlorite versus hydrogen peroxide) were evaluated as part of the R&D testing.

Data Sources Data that formed the basis of the process train evaluation originated from multiple sources, including online instruments, field measurements, and discrete sampling events. These data included both physical data (i.e., process flows, process pressures, etc.) and water quality data (i.e., turbidity, pH, conductivity, Continued on page 42

master spreadsheet. While the process of transferring data was not particularly difficult in itself, ample time of approximately three to four hours each week was allotted to perform the data transfers, quality-check the data, and troubleshoot instruments as needed.

Online Instrumentation Online instruments served a critical role throughout the R&D testing, allowing operators and engineers to remotely monitor the R&D plant data. On many individual unit processes, online instruments provided continuous monitoring of various process parameters via a digital display and internal data logging (i.e., temperature, conductivity, ozone transfer efficiency, process pressures, flow, tank levels, etc.) that enabled the automation of numerous system functions. These online instruments also provided excellent operational data for both physical operating parameters and select water quality parameters, including turbidity, conductivity, and TOC. The R&D plant operators typically transferred data from online instruments into a master Excel spreadsheet once a week. The master spreadsheet for data management was developed by CDM Smith at the beginning of the project with preset plots, which helped operators and engineers quickly recognize anomalies in the operating data. With five months of testing planned for each WRF, the early effort of developing the spreadsheet and plots prior to receiving data was critical for making process decisions quickly and staying on schedule. Raw data from the UF-LPRO system were stored in an online database and managed by the system manufacturer. Raw data from the Ozone-BAF system were stored on USBs, located inside the equipment panels onsite. Also, data stored by the inline TOC analyzers were copied to a flash drive, then uploaded into the

Field Measurements Data obtained from online instruments were supplemented with data obtained from field measurements. Field-measured data included both physical operating parameters and water quality parameters. In some instances, field measurements were intended to verify information obtained from online instruments (i.e., conductivities, pH values, turbidity values, etc.). In other instances, field measurements were intended to generate new information, either to monitor the operation and performance of individual unit processes (i.e., dissolved oxygen concentrations, adenosine triphosphate [ATP] concentrations, TOC concentrations, etc.) or to minimize the potential for process interruptions (i.e., bulk chemical tank levels, differential pressure across basket strainers, etc.). Field-measured data associated with individual unit processes are summarized in Table 1. Physical operating data were collected daily, and field water quality analyses were typically conducted four times each week. Routine Sampling Events Routine sampling events were conducted on a weekly basis throughout the R&D testing to monitor the performance of individual unit processes, as well as the overall treatment process systems. Each of these routine sampling events involved the collection of over 350 discrete samples from various process streams, followed by their packaging and shipment to a certified analytical laboratory for subsequent analysis. Generally, performing routine sampling events required two R&D plant

Table 1. Field-Measured Data and Equipment Utilized

operators to be onsite for at least eight hours each. Additional follow-up with the laboratory was often required to coordinate sampling schedules and notify the laboratory of any changes in sampling protocol, if required. Comprehensive Source and Purified Water Sampling Events Comprehensive source water and purified water sampling events were conducted during the R&D testing to provide a holistic assessment of the R&D plant source water quality and purified water quality from each purification process. Each of the periodic purified water sampling events involved the collection of discrete water samples from six specific locations within the process systems (R&D plant source water, UF-LPRO permeate, UF-LPRO-AOP purified water, UF-LPRO concentrate, OzoneBAF treated water, and Ozone-BAF-AOP purified water). Typically, these sampling events required four operators to be onsite for at least six hours each. This testing protocol allowed for the direct comparison of the two treatment processes. Once collected, all samples were packaged and shipped to a certified analytical laboratory for subsequent analysis. In addition to primary and secondary drinking water standards, more than 250 currently unregulated constituents (i.e., terpenes and fragrances, pharmaceuticals, pesticides and herbicides, etc.) were investigated for each sampling event.

Operational Lessons Learned This section focuses on the specific operational lessons learned over the 10-month R&D study. To accurately explain abnormalities in operating and water quality data, the importance of good recordkeeping should be emphasized throughout. Accurate documentation and written records were essential in determining the cause for equipment interruptions and assisted in identifying similar issues on other equipment. Close collaboration with WRF staff on scheduling and planned maintenance activities also helped overcome challenges encountered during potable reuse R&D testing. Research and Development Plant Source Water Variability The R&D testing was conducted over an approximately 10-month period. The largest fluctuations in R&D plant source water quality were related to temperature and seasonal variability. For example, atypical operating conditions at Southwest WRF arose from the proliferation of filamentous-bulking bacteria within the wastewater treatment process, as well as the subsequent actions implemented by the

42

Southwest WRF operations staff to remedy the situation (i.e., chlorination of the return activated sludge). Ultimately, the plant upset at the Southwest WRF and the lower coagulant dose being evaluated at the R&D plant during that time resulted in elevated values for several water quality parameters, including but not limited to, turbidity, TOC, and total nitrogen. Variability in the source water characteristics was also observed during the R&D testing at Buckman WRF, which is JEA’s largest treatment plant, with a permitted average capacity of 52.5 mgd. Loading conditions to the R&D plant varied on a daily basis, which is indicative of its commercial and industrial customer base.

installed in the Stage 2 pressure vessels. The programming issue and alarm settings were corrected, a manual pressure relief valve was installed as a backup, and the displaced O-ring was replaced. Water quality data were closely monitored following the overpressure event, and it was decided that the event caused a slight compromise in the integrity of the Stage 2 elements, which were subsequently replaced S Power Outages – The regularly scheduled

generator testing conducted by WRF plant staff was generally well-coordinated with R&D plant operations and did not cause any unexpected challenges; however, unplanned power outages (i.e., short “blips” in power supply) would sometimes cause significant challenges, particularly for the UF-LPRO pilot system. For example, a power interruption could cause the breaker on the Continued on page 44

Troubleshooting Equipment The R&D plant typically operated 24 hours a day, seven days a week. Troubleshooting equipment issues and performing preventative maintenance were key aspects in ensuring satisfactory operation of the R&D plant by reducing the frequency of unplanned shutdown events. This section highlights the normal maintenance duties and specific equipment issues encountered by the R&D plant operators. Most, if not all, of these equipment issues were related to the challenges inherent with the modular, pilotscale systems being tested. Full-scale water purification facilities include many additional design features (i.e., integrated alarms, supervisory control and data acquisition [SCADA], backup power, etc.) to avoid these issues and provide a reliable and robust treatment process. Ultrafiltration and Low-Pressure Reverse Osmosis System From an operational perspective, the UFLPRO process generally provided consistent and reliable operation. While operational anomalies were experienced during R&D testing, these irregularities did not arise from inherent flaws or limitations of the UF-LPRO process itself. Operational abnormalities included programming issues, unplanned shutdown of chemical feed systems, unplanned power outages, etc., and are explained in more detail in the following section. S Programming and Controls – In December 2017, while the R&D plant was operating at the Southwest WRF, an anomaly associated with the programming and controls of the LPRO pilot unit resulted in temporary overpressurization of the LPRO system. This overpressurization event displaced an O-ring that served as a barrier between the feed/concentrate and the permeate streams and damaged the membrane elements Florida Water Resources Journal • February 2020

Continued from page 43 chemical feed pump system to trip, resulting in loss of chemical feed. Also, losing power would cause the online TOC analyzers to cycle off and on, and sometimes resulted in lost data. Ozone-Biologically Active Filtration System Generally, R&D plant operators focused their daily onsite efforts on the Ozone-BAF system. While this system was fully automated, it included more operationally complex unit processes and required more daily maintenance. The primary activities associated with maintaining the Ozone-BAF system are described. S Flocculation-Sedimentation Feed Pump – The Ozone-BAF system was deliberately shut down approximately four times per week to clean the feed pump impeller to the flocculation-sedimentation system. Daily monitoring of the feed pump power output (0 to 100 percent) allowed operators to identify when the pump was getting clogged. The impeller was typically clogged with debris. An inline basket strainer was installed upstream of the equalization tank to help with this problem; however, it didn’t significantly reduce cleaning frequency. Replacement of the feed pump with a pump that is more capable of pumping solids is advised for future projects of this nature. S Ferric Chloride Sludge Waste – The sludge handling system was inspected daily for evidence of floc carryover and/or sludge buildup. The settled floc (sludge waste) was removed intermittently from the sedimentation basin and conveyed to a lift station, which pumped to the headworks of the WRF. The pilot equipment used was designed for typical conditions, and for this project, it was undersized for the coagulant dose required. To help prevent clogging of the sludge collection system, the highest-available sludge flow rate of approximately 1.4 gal per minute (gpm) was used; however, the hoses on the sludge collection system would clog periodically, causing a motor fault alarm and the system to shut down. In addition, due to the high ferric dosages used for this project, the sludge collection motor seal required periodic replacements (three times total), resulting in additional downtime. S Ozone Destruct Catalyst – The ozone-laden off-gas from the ozone system flowed through off-gas piping and an ozone destruct catalyst to remove ozone. During hotweather periods, the water would reach temperatures greater than 88°F. The resultant off-gas during the hot-weather periods was very humid and caused excessive condensation on the inside of the off-gas piping and

44

destruct catalyst chamber, effectively reducing the life of the catalyst dramatically. This caused the catalyst to undergo frequent replacement, requiring the Ozone-BAF system to be shut down. It’s advised that future projects performed during hot-weather periods be equipped with heaters upstream of the destruct catalyst to drive out excessive moisture. This issue was associated with the pilot-scale equipment and is not typically an issue with full-scale equipment. Advanced Oxidation Unlike the other unit processes, UV-AOP was operated in a batch mode only once a week during sampling. The AOP system was operated in batch mode because the process required constant operator attention. Also, instead of renting separate UV-AOP systems for each process train, one UV-AOP system could be used in a batch mode operation. The UV lamps always operated at the same power setting, and the feed flow rate was varied using manual valves to reach the target dose. Based on the feed flow rate, operators used an Excel spreadsheet to calculate the required chemical feed rate; they then manually adjusted the speed on the chemical dosing pump. The AOP system was manufactured in Switzerland and operated on a 50-Hertz (Hz) power supply, which is different from the 60-Hz supply used in the Unites States. To convert power to the proper setting required for the AOP system, an additional power inverter and transformer were located outdoors adjacent to the AOP system in an enclosed container. While the direct cause of the error is unknown, the AOP system stopped working in August 2017 during the R&D testing at Buckman WRF. An error message was displayed on the power inverter, and operators called upon advice from JEA electricians, the contractor who installed the equipment, the AOP system manufacturer, and the power supply manufacturer (working remotely from Switzerland). Despite best efforts, the AOP system remained inoperable for approximately three weeks until a rental power inverter unit was obtained from a U.S.-based company, shipped to the R&D plant at Buckman WRF, and installed by a certified electrician. Safety Safety was the highest priority for the operation of the R&D equipment. Significant onsite hazards included high-strength chemicals, tripping hazards due to the temporary nature of the facility, heat exhaustion, etc. The CDM Smith operators were trained by the chemical supplier to safely store, pump, and transfer chemicals from bulk storage drums to day tanks

required by the UF-LPRO-AOP and OzoneBAF-AOP treatment trains. To ensure safety while handling chemicals, a protocol was created to define the following: S Personal protective equipment that should be worn with each type of chemical S Procedures for transferring chemicals S Procedures for addressing chemical spills S Procedures for chemical storage The chemical storage area and path for chemical transfer were arranged to make the transfer of chemicals as convenient and safe for operators as possible. In addition, several ambient ozone analyzers were located inside the equipment buildings to monitor ambient ozone and shut down the ozone unit if levels reached the short-term exposure limit. If an alarm condition occurred, a light beacon would blink outside the building to indicate whether it was safe to enter.

Conclusions and Recommendations Operational data and water quality monitoring results from this study demonstrate the feasibility of both water purification technologies to produce purified water that meets drinking water quality standards and goals established for the R&D testing, but the UFLPRO-AOP process exhibited more reliable operation and was less subject to variations in source water quality. Based on this comparison, and along with the life cycle cost estimates provided in the cost evaluation report, CDM Smith recommended the UF-LPRO-AOP system for the demonstration and implementation of JEA’s water purification program. If a utility is considering the development of a potable reuse R&D pilot program, the information presented will provide a better understanding of operator responsibilities, process actions, and lessons learned from the 10-month R&D study in Jacksonville.

Acknowledgments The authors would like to thank the JEA staff and operators at Southwest WRF and Buckman WRF for their thoughtful planning, dedication, and willingness to help throughout the R&D project. Additionally, many thanks are due to the JEA team, including Paul Steinbrecher, P.E.; Todd Mackey, P.E.; Tom Bartol, P.E.; Tim Mechum and Chris Howard; and the CDM Smith team, including Shayne Wood, P.E., BCEE; Patrick Victor, P.E., BCEE; Colin Hobbs, P.E., BCEE; and Jeremy O’Neal, P.E., for their expertise, exceptional attention to detail, and drive to move the project forward each day.

Company Participation in BBQ Challenge is a Success For the sixth time, Garney Construction participated in the Florida Section of the American Water Works Association (FSAWWA) BBQ Challenge. The latest competition was held December 2019 at the section’s Fall Conference at Omni Orlando Resort at ChampionsGate. At the competition, cook master Ryan Smith, along with the help of several other employee-owners, served up his famous rib recipe that was a hit among the crowd. What is the trick to their “talk of the town” meats? According to Walker Petty, project engineer for Garney Construction, who was present at the event, “We put the same focus in our barbecue that we do in all of our projects. We were dedicated, as we worked 24 hours straight to make sure we had the right amount of cook time. We focused on quality, taking the time to trim the cuts perfectly. Finally, we care about customer satisfaction, whether it was with plating, service, or portion size—we were there to make sure that those we served were happy about their decision to stop by our booth.” Petty rated the company’s involvement in the competition this year an overall success. “The water industry is such a small, close-knit community, and as a company we were pleased with having yet another great opportunity, through service, to show our customers, engineers, and product partners why our company can be the best option.” Overall, the veranda of the hotel where the challenge took place was filled with live music, the smell of great barbecue, and an opportunity for key players in the water industry to connect. From humble beginnings, this FSAWWA event has continued to grow, and it hosted more than 750 participants for the end-of-theyear event. Garney looks forward to supporting the event again in 2020.

North Hillsborough Aquifer Recharge Project Expands Saltwater Intrusion Barrier Deborah Daigle and Michael Townsel n 2009, the Hillsborough County Public Utilities Department (HCPUD) began evaluating the feasibility of using highlevel disinfection public access-quality reclaimed water to provide environmental improvements, act as a barrier to saltwater intrusion, create a path to the restoration of water use caution area (WUCA) water levels, and support a long-term and sustainable solution to water management challenges in its service area. The Southwest Florida Water Management District (SWFWMD) has established minimum aquifer levels to be met for prevention or reduction of saltwater

intrusion along the Hillsborough County coast. The county’s goal of 100 percent reuse capability is the driver behind the development of reclaimed water direct aquifer recharge pilot projects along the coastal county. The county’s South Hillsborough Aquifer Recharge Project (SHARP), located at the Port Redwing Outfall (near Apollo Beach), became the first reclaimed water direct aquifer recharge project in the region. The SHARP project targets saltwater intrusion in the most-impacted area (MIA) of the southern WUCA (SWUCA). The county has continued this program in the northwest

service area by initiating a similar project, phase 1 of the North Hillsborough Aquifer Recharge Project (NHARP), which will also create a salinity barrier and improve water levels within the northern Tampa Bay Water WUCA. The NHARP recharge well (RW-1) is located at the Northwest Hillsborough County Dechlorination Facility (NHCDF) in Tampa. Public access reclaimed water is provided by the Northwest Hillsborough County Water Reclamation Facility (NHCWRF) in Odessa. The RW-1 will recharge up to 3 mil gal per day (mgd) of high-level disinfection public access-quality reclaimed water into the Avon Park Formation of the Upper Floridan aquifer (UFA) system. The HCPUD is now planning phase 2 of the NHARP expansion and installation of additional Class V recharge wells in the northwest county area. The HCPUD goal is to complete future wells farther inland from the coast in areas where the top of the Avon Park Formation is closer to 10,000 mg/L total dissolved solids (TDS). Construction of the first NHARP recharge well and monitoring well began in August 2017. Since the position of the underground source of drinking water (USDW) was unknown at the NHCDF site, the recharge zone monitoring well (RZMW1) was drilled first. The depth of the base of the USDW, defined as water with 10,000 mg/L TDS, was determined to be approximately 500 ft below land surface (bls) within the Ocala Limestone. The recharge zone for NHARP is the Avon Park Permeable Zone (APPZ) within the UFA system. The wells, pipelines, and electrical/supervisory control and data acquisition (SCADA) at the NHARP site were completed in March 2019, with operational testing completed in mid-2019.


Operational data from SHARP indicates that the water levels have increased from approximately -5 ft National Geodetic Vertical Datum (NGVD) to 18.2 NGVD in the RZMW. The freshening of the Avon Park Formation has greatly improved water quality near the coast and the SHARP recharge well, thus creating a barrier to salt water intrusion. Operational challenges observed from SHARP include a loss of well capacity due to fouling. In response, the county has implemented a standard operating procedure to acidify the well when injectivity is reduced to 25 gal/pounds per sq in. (psi).

Background In Florida, saltwater has intruded through a number of pathways, including the following (Prinos, 2013): S Encroachment of seawater into aquifers in response to decreased fresh groundwater levels relative to sea level. S The flow of saltwater inland through canals, rivers, boat basins, and coastal marshes, and subsequent leakage of this saltwater into aquifers. S The movement of connate or relict saltwater in an aquifer. S Leakage of saltwater between aquifers. The reductions in fresh groundwater levels are caused by public and private water supply withdrawals from aquifers, excessive drainage, reductions in precipitation, or increases in sea level. The HCPUD embarked on an innovative program that utilizes highly treated reclaimed water to recharge the UFA along its coastal areas to provide a saltwater intrusion barrier. The source water for the aquifer recharge program is excess reclaimed water from the county’s wastewater treatment plants. In 2009, HCPUD began evaluating the feasibility of using highly treated wastewater from its existing advanced water reclamation facilities (WRFs) in support of a sustainable solution to water management challenges in the southern portion of its service area. The ultimate goal of HCPUD is 100 percent reuse capacity.

Eastern Tampa Bay (ETB) were primarily caused by regional groundwater withdrawals that resulted in lowered lake and wetland levels in the NTB and saltwater intrusion in the ETB. In response to the lowered groundwater and lake levels, the county’s governing board declared each of the areas as WUCAs in 1989. Out of concern for impacts to water resources in ETB, the governing board in 1992 established the SWUCA, encompassing both the ETB and Highlands Ridge WUCAs and all of the area in between. Specifically, the SWUCA encompasses an area of about 5,100 sq mi and covers the southern half of the district, including portions of the county. Historical increases in groundwater withdrawals have resulted in significant saltwater intrusion in coastal portions of the UFA, the principal source of public water supply in the region. In 1990, the district designated the coastal area of the ETB WUCA as the MIA (Figure 1). The SWFWMD has since established minimum aquifer levels to be met for prevention or reduction of saltwater intrusion within SWUCA. In the NTB WUCA, most of the groundwater use is for public supply. As a result, most of the water resource impacts are in areas surrounding the major public supply wellfields, although models do confirm isolated areas of saltwater intrusion. In the NTB WUCA, the Tampa Bay Water central wellfields withdraw an annual average of 90 mgd of groundwater from the UFA. In 1988, Tampa Bay Water operated these wellfields at 192 mgd, but environmental impacts lead to the required reduction per the consolidated

water use permit. Today, Tampa Bay Water operates the wellfields as an interconnected system at this lower pumping limit to promote environmental recovery. In addition, SWFWMD’s goal is to continue evaluating the amount of environmental recovery that can be achieved while withdrawals remain at 90 mgd. Tampa Bay Water is preparing a recovery assessment report that will evaluate the status of the environmental recovery and will also identify any remaining adverse impacts that were not addressed with the pumping reduction.

Hillsborough County Implements Aquifer Recharge to Address Impacts in the Most-Impacted Areas and North Tampa Bay Water Use Caution Area The SHARP is located at the Port Redwing Outfall near Apollo Beach and is the first reclaimed water direct aquifer recharge project in the region (Figure 2). The SHARP project targets saltwater intrusion in the MIA of the SWUCA. The SHARP recharge system began testing operations with injection of reclaimed water in July 2015. The system consists of one Class V aquifer recharge well, one recharge zone monitoring well, and two overlying monitoring wells. Expansion of the program is underway with the installation of two new Class V wells. The injectate water quality is advanced wastewater treatment high-level disinfection effluent from the county’s south central public access reuse system. Continued on page 60

History of Groundwater Withdrawal Impacts in Hillsborough County In the late 1980s it was noted that declines in groundwater levels had occurred in three regions. Declines in the Highlands Ridge, Northern Tampa Bay (NTB) and

Continued from page 59 The county has continued this program in the northwest service area by initiating a similar project (NHARP, phase 1), which will also create a salinity barrier and improve water levels within the NTB WUCA. The NHARP recharge well (NRW-1) is located at the NHCDF in Tampa (Figure 2). A north recharge zone monitoring well (NRZMW-1) was also installed at the facility approximately 1,200 ft northeast of NRW-1. Public access reclaimed water is provided by the NHCWRF. The RW-1 will recharge up to 3 mgd of highlevel disinfection public access-quality reclaimed water into the Avon Park Formation of the UFA system. The wells, pipelines, and electrical/SCADA were completed in March 2019, with operational testing done later that year. The HCPUD is planning phase 2 of the NHARP expansion and installation of additional Class V recharge wells in the northwest county. The county’s aquifer recharge program includes a regional recharge system to provide a level of mitigation to the NTB WUCA and to allow for additional groundwater development in an area that has had historically adverse water level impacts to the aquifer. It’s anticipated that at least seven aquifer recharge wells will be constructed as part of NHARP in several phases over the next 10 to15 years. Each well is anticipated to operate at 3 mgd annual average daily flow (AADF). Additionally, the construction of deep exploratory wells and associated monitoring wells will be initially required to characterize the aquifer in this project area. The total anticipated recharge quantity of the NHARP well program is 21 mgd AADF. The location of future aquifer recharge wells will be adjusted inland per the SWFWMD to areas where the TDS of the top of Avon Park Formation is in the 10,000-mg/L TDS range. The top of the Avon Park at NHARP had a TDS range of approximately 15,000 to 18,000 TDS. The salinity profile into the Avon Park Formation at the SHARP and NHARP sites was unknown prior to drilling of the wells. As shown in Figure 3, future South Hillsborough Aquifer Recharge Expansion (SHARE) well locations are approximately 2 mi inland from the original SHARP location, which is also closer to HCPUD’s reclaimed infrastructure. The NHARP expansion wells are also planned to be located farther inland from the NRW-1 site. The drilling of monitoring wells will be performed first at the new recharge sites to confirm the salinity profile.


North Hillsborough Aquifer Recharge Project Site Hydrostratigraphy and Recharge Zone The target recharge zone for the NHARP recharge well is the APPZ of the UFA system (Figure 4). The lowermost permeable zone of the UFA is defined as occurring in the hard, fractured dolostone within the Avon Park Formation. The permeability of this zone is due primarily to fractures and interconnecting solution cavities and has been identified as the APPZ (Reese and Richardson, 2007). The APPZ usually lies between the UFA and the Lower Floridan aquifer and within the middle confining unit. This subaquifer is present over most of southern peninsular Florida and characteristically consists of thick units of dolostone with interbedded limestone in its upper part. Permeability in the APPZ is primarily associated with fracturing. The APPZ is the primary production zone in inland areas of Florida and the county. Regional mapping shows the top of the APPZ at approximately 620 ft bls (600 ft below mean sea level NGVD) with a thickness of over 500 ft (Reese and Richardson, 2007) at the NHARP site. The actual top of the APPZ at the NHARP site is encountered much deeper, at approximately 740 ft bls (725 ft below mean sea level). Primary fracture zones within the APPZ were detected at both NHARP wells at depths of approximately 750, 820, and 900 ft bls during drilling, and geophysical logging indicates that most of the flow in the borehole is from these fracture zones. Below the fractured dolostone zones are dolomitic limestone and limestone. The APPZ contains adequate porosity and permeability (including significant fractures and voids) to accommodate an injection rate of 3 mgd. A specific capacity of 700 gpm (gal per minute)/ft was measured in well NRW-1 at the end of the constant rate pumping test at 2,500 gpm. The base of the APPZ was noted by the presence of evaporites at a depth of approximately 1,180 ft bls at the NHARP site. Overlying the Avon Park Formation is the Ocala Limestone, a semiconfining unit that does not readily produce water and retards the upward movement of injectate. The Suwannee Limestone is found at the NHARP site above the Ocala Limestone between approximately 190 and 480 ft bls. The Suwannee Limestone aquifer is used extensively for fresh water supply and has been identified by SWFWMD as a critical aquifer needing water level increases to

Table 1. North Hillsborough Aquifer Recharge Project Well Construction Details

mitigate saltwater intrusion. At NHARP the Suwannee Limestone contains slightly brackish water (TDS ~850 mg/L). Above the Suwannee Limestone is the Tampa Member which is between approximately 100 and 190 ft bls at the NHARP site and contains fresh water (TDS ~350 mg/L). To determine the confining characteristics of the stratigraphic units above the recharge zone, rock coring and packer testing was performed. Rock coring indicates low permeability strata between the depths of 464 to 677 ft bls, with vertical hydraulic conductivity ranging from 5.7 x 10-6 cm (centimeters)/sec to 7.2 x 10-11 cm/sec. The very low vertical hydraulic conductivities measured for the core samples collected confirm the confining characteristics of each of the cored intervals. Straddle packer tests were conducted at well NRW-1 at the following depths: S Packer Test No. 1: 717 to 739 ft bls S Packer Test No. 2: 688 to 710 ft bls Calculated hydraulic conductivity for the test intervals was 22 ft/day for Test No. 1 and 16 ft/day for Test No. 2. The relatively low hydraulic conductivities measured during packer tests indicate that the tested intervals are confining. The packer tests generally estimate the hydraulic properties of the interval tested in the horizontal plane. The vertical hydraulic conductivity of the type of materials encountered in the tested intervals

is a typical order of magnitude less than the horizontal hydraulic conductivity. In addition to the coring and packer tests, sonic porosity logs also indicate a continuous interval of comparably low sonic porosity located above the first fracture zone within the Avon Park Formation (low porosity interval extends from approximately 710 to 740 ft bls) at each well.

North Hillsborough Aquifer Recharge Project Well Construction Construction of the first NHARP recharge well and monitoring well began in August 2017 under a Class V, Group 2 construction and testing permit from the underground injection control (UIC) division of the Florida Department of Environmental Protection (FDEP). Since the position of the USDW was unknown at the NHCDF site, the NRZMW-1 was drilled first. The depth of the base of the USDW, defined as water with 10,000 mg/L TDS, was determined to be at a depth of approximately 500 ft bls within the Ocala Limestone portion of the geologic section. The TDS then increased to over 25,000 mg/L below a depth of approximately 800 ft bls in the Avon Park Formation during drilling. The RZMW-1 was completed with 703 ft of a 6-in.-diameter fiberglass reinforced plastic (FRP) casing with an open hole backplugged to 920 ft bls. The goal of FDEP was Continued on page 62

Continued from page 61 that the monitoring well be completed to isolate the main flow zones within the recharge interval (Figure 4). Two existing shallow monitoring wells (SMW-1 and SZMW-2) were also incorporated into the program at NHARP to monitor the Tampa Member and Suwannee Limestone within the USDW. The wells are completed to depths of 170 and 410 ft bls, respectively.

Operational Observations and Challenges for the Aquifer Recharge Systems Although the NHARP recharge well is not yet operational, HCPUD has operated the SHARP recharge well since 2015. The RW-1 is located on the southern side of the Port

diameter well, with a permitted annual average injection capacity of 3 mgd and a maximum daily injection capacity of 4.5 mgd. The RZMW-1 is located ~1200 ft to the east and monitors the injection zone. Monitor wells (TPW-1 and SMW-1) are utilized to monitor overlying intervals and aquifer zones above the injection interval and are located ~150 ft. north and ~65 ft. northeast of RW-1, respectively. Injection of reclaimed water commenced in July 2015. During the initial discharge of reclaimed water into RW-1, injection rates were initially established at less than 0.5 mgd to condition the well and the Avon Park Formation, but subsequently increased to 1 mgd based on wellhead pressure. Recharge flow rate was increased to 2 mgd in March 2016, with an initial wellhead pressure of 25

Figure 5. Water Levels at South Hillsborough Aquifer Recharge Project Monitoring Wells

Redwing Discharge Facility, is a 16-in.-

psi. During November 2016, HCPUD increased the targeted recharge flow rate to 2.5 mgd, with an initial wellhead pressure of 73 psi. Figure 5 presents water levels in the SHARP monitoring wells and two regional monitoring wells. The regional wet season and dry season trends can be clearly observed in the overlying monitoring wells consistent with the offsite regional wells. While the seasonality is still visible at RZMW-1, the steady water level increase can be attributed to the injectate. The water levels in RZMW-1 clearly indicate an upward change in water levels in the Avon Park Formation. Water levels have increased from approximately -4 ft to 18.2 NGVD since operation began. Moderate seasonal variability between wet and dry seasons continues and this increase in water level elevation can be attributed to freshening in water quality at this well associated with the horizontal movement of reclaimed water from the recharge well. The increase in water level by an average of approximately 23.5 ft within the Avon Park Formation supports the SWFWMD SWUCA recovery strategy of mitigating saltwater intrusion. The RZMW-1 has indicated a steady decrease in salinity due to the horizontal movement of the fresher reclaimed water within the saline recharge zone. From August 2015 through December 2016, the TDS concentration at RZMW-1 exhibited a decreasing trend from 35,000 to 3,700 mg/l. Water quality at RZMW-1 shows significant freshening, as there is ongoing mixing occurring between the reclaimed water and the saline water in the injection zone. This high degree of mixing is not unexpected due to the highly fractured nature of the injection zone. The release of arsenic at RZMW-1 has fluctuated following acidification events, but now appears stable. No significant metals mobilization has been observed at RZMW-1.

Operational Challenges

Figure 6. Injectivity Versus Daily Flow at South Hillsborough Aquifer Recharge Project

February 2020 • Florida Water Resources Journal

Operational challenges at SHARP, including declines in well performance associated with dissolved and suspended solids in the injectate, have been observed at RW-1. Using a total suspended solids value of 0.5 mg/l and a TDS value of 500 mg/l, there is potential to deposit ~1,500 lbs of solids per mil gal injected annually and an extensive amount of precipitation based on the measured oxidation reduction potential. The chemical precipitation of calcium carbonate in the formation fractures, combined with


suspended solids deposition, appears to be the primary cause of reduced injection capacity. The HCPUD is utilizing the specific injectivity (SI) as an indicator parameter to declining well performance. The SI is calculated as the average daily injection rate divided by the average daily injection pressure and has been utilized in addition to the required parameters to evaluate injection capacity and system performance. Operational data to date indicate that an SI below 25 gal/psi results in reduced system control and wellhead performance. The HCPUD has developed a standard operating procedure to acidify the well when the SI is less than equal to 25 gal/psi. The SI plotted against the daily average injection rate with an SI threshold of 25 is shown in Figure 6 and clearly identifies reduced system performance prior to an acidification event and enhanced performance following an acidification event. The SI is being used to plan future acidification events. These observations continue to support the position that acidizing is a successful procedure to properly maintain the recharge system for beneficial use in the SWUCA. The total volume injected at SHARP from July 2015 through Sept. 5, 2019, is approximately 3.105 bil gal.

Conclusions In 2009, HCPUD began evaluating the feasibility of using highly treated wastewater from its existing advanced water reclamation facilities to provide environmental improvements, a barrier to saltwater intrusion, a path to the restoration of WUCA water levels, and support of a long-term and sustainable solution to water management challenges in its service area. Implementation of SHARP and NHARP will create a salinity barrier along two areas of the county coastline where impacts from groundwater withdrawals have been documented. Operation of the SHARP project for approximately three years has shown an increase in water levels and the freshening of the Avon Park Formation, which has greatly improved water quality near the SHARP recharge well, thus creating a barrier to saltwater intrusion. Expansion of both the SHARP and NHARP along the coastal county will expand this barrier and potentially allow for new groundwater development inland in fresher portions of the aquifer. The county is currently installing two additional recharge wells for the SHARP Florida Water Resources Journal • February 2020

C FACTOR

A New Year and New Officers, and What You Need to Know About Potable Reuse Kenneth Enlow President, FWPCOA

reetings, everyone. By this time, we all should be settling into the routines of the new year and moving forward to the tasks at hand.

his tenure helping to make us a stronger organization and increasing membership. I also want to welcome Athena Tipaldos to the position of secretary-treasurer-elect as she takes on the role of a state officer. She will be an asset to the organization with her background in the industry and her enthusiasm.

A Discussion on Potable Reuse As promised in my January column, I would like to talk about potable reuse; specifically, about indirect and direct potable reuse.

FWPCOA Officers The new FWPCOA officers for 2020 were seated at the board of directors meeting held at the Emerald Grande at HarborWalk Village in Destin on January 18. The new officers are: Ken Enlow - President Patrick Murphy - Vice-President Mike Darrow - Past President Rim Bishop - Secretary-Treasurer Athena Tipaldos - Secretary-Treasurer-Elect Please welcome the new officers and don’t hesitate to contact any one of us if you have questions or needs. Contact information is available on the FWPCOA website at www.fwpcoa.org. I want to thank Mike Darrow for his dedicated service as the president of FWPCOA over the last two years. Mike did a fantastic job during

First of all: What are we talking about? Indirect potable reuse – This refers to the method of discharging reclaimed water from a wastewater treatment plant to groundwater or surface water to supplement the water supply to a potable water treatment plant. Direct potable reuse – This refers to adding reclaimed water from an advanced wastewater treatment facility into a raw water supply prior to a drinking water treatment facility or directly into the “potable” water distribution system intended for human consumption. There are two basic types of direct potable reuse systems: 1. Advanced treated reclaimed water is introduced upstream of a water treatment facility into the raw water source for a water treatment facility.

February 2020 • Florida Water Resources Journal

2. Advanced treated reclaimed water is introduced directly into the potable water distribution system. Florida’s population is one of the fastest growing in the United States. Although we are surrounded by water, suitable and clean water resources are limited. Continuing to withdraw water from groundwater and surface water sources to maintain this growth could have a serious impact on the natural system and the ability for it to replenish the sources through the hydrological cycle. By introducing reclaimed water from advanced wastewater treatment facilities into the source water, the natural system can be augmented, and therefore take some of the demand off of the natural system. What else could be driving the need to look to potable reuse? Possible changes in regulations could restrict or prohibit discharge of wastewater effluent to surface water sources under certain conditions in the future. This could leave potable reuse as an alternative to current wastewater discharge practices. Where do we go from here? Federal regulations do not exist for potable reuse and regulations vary from state to state where potable reuse has already been practiced. Going forward, Florida will need to establish


regulations for potable reuse. Some of the key questions to be answered are: S How do we permit facilities? S What type/level of operator licenses will be needed? S Are there any changes needed to be made related to water quality regulations for both potable reuse water entering the potable treatment system and finished water entering the distribution system? How can you help? The FWPCOA is working with the Potable Reuse Commission to develop a position statement that would reflect the opinion of the operators we represent concerning potable reuse operator certification and training. A survey has been put together by our Reuse Committee to give the membership a chance to provide their thoughts and input about potable reuse. We hope to have the survey available on the FWPCOA website later in February or early March. It’s very important that the committee gets input from the membership in order to have a clear understanding of our members’ thoughts for our opinion statement. Every opinion counts and this is your chance to express

your thoughts, concerns, and needs for the future of reuse. A case study of a reuse pilot project completed at the City of Clearwater will be presented by Emilie Moore, with Tetra Tech Inc., at the Operators Showcase on Sunday, April 26, at this year’s Florida Water Resource Conference in West Palm Beach. This should be an interesting presentation and a chance for operators to ask questions and provide input.

Upcoming Events Don’t forget to register for the FWPCOA Spring State Short School, which will be held in Ft. Pierce the week of March 16 through March 20. Also, don’t forget to register for the Florida Water Resource Conference, being held April 26 through April 29 in West Palm Beach. That’s it for this C Factor. Keep up the good work. Stay active and make a difference! S
