CITY OF SOUTHLAKE | WATER QUALITY REPORT 2022

A Guide to Your Water Quality

Definitions and Abbreviations AL: Action level; The concentration of a contaminant, which, if exceeded, triggers treatment or other requirements that a water system must follow per EPA and TCEQ mandates.

AVG: Average; Regulatory compliance with some maximum contaminant levels (MCLs) are based on running annual average of monthly samples.

Level 1 Assessment: A Level 1 assessment is a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.

Level 2 Assessment: A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an Escherichia coli (E. coli) maximum contaminant level (MCL) violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.

MCL: Maximum Contaminant Level; the highest level of a contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

MCLG: Maximum Contaminant Level Goal; the level of a contaminant in drinking water below which there is no known or expected health risks. MCLGs allow for a margin of safety.

MRDL: Maximum Residual Disinfectant Level; the highest level of disinfectant allowed in drinking water. There is evidence that addition of a disinfectant is necessary for control of microbial contaminants.

MRDLG: Maximum Residual Disinfectant Level Goal; the level of a drinking water disinfectant below which there are no known or expected health risks.

MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

MFL: million fibers per liter (a measure of asbestos).

MRL: Minimum Reporting Level; the lowest concentration of a constituent or a contaminant that can be measured by a laboratory. mrem: millirems per year (a measure of radiation absorbed by the body).

N/A: Data field not applicable to the particular constituent we are reporting information about.

NTU: Nepholomeric Turbidity Units; a measure of water turbidity or clarity. pCi/L: Picocuries per Liter; a measure of radioactivity. ppb: Parts per Billion or micrograms per liter (µg/L). ppm: Parts per Million or milligrams per liter (mg/L). ppq: parts per quadrillion, or picograms per liter (pg/L). ppt: parts per trillion, or nanograms per liter (ng/L).

TT: Treatment Technique; a required process intended to reduce the level of a contaminant in drinking water.

CITY OF SOUTHLAKE | WATER QUALITY REPORT 2022

This describes some of the ways contaminants enter drinking water; wording is provided by EPA and may or may not apply to the City of Southlake.

Southlake’s Water Source The City of Southlake gets all of its water from the City of Fort Worth’s Water Department. Fort Worth obtains water from surface water sources: Lake Worth, Eagle Mountain Lake, Lake Bridgeport, Richland Chambers Reservoir, Cedar Creek Reservoir, and the Clear Fork Trinity River (from Lake Benbrook). Fort Worth owns Lake Worth. The U.S. Army Corps of Engineers is responsible for Lake Benbrook. The other four lakes are owned and operated by Tarrant Regional Water District (TRWD).

TCEQ Assesses Raw Water Supplies The Texas Commission on Environmental Quality (TCEQ) completed an assessment of Fort Worth’s, and subsequently, Southlake’s source waters. TCEQ classified the risk to our source waters as high for most contaminants. High susceptibility means there are activities near the source water watershed that make it very likely chemical constituents may come into contact with the source water. It does not mean there are any health risks present. TRWD, from which Southlake ultimately purchases its water, received the assessment reports.

• For more information on source water assessments and protection efforts at our system, contact Southlake Water Utilities at (817) 748-8082.

• Further details about the source water assessments are available at www.tceq.texas.gov/gis/swaview.

• Further details about sources and source water assessments are available through the Texas Commission on Environmental Quality at www.tceq.texas.gov/drinkingwater.

Water Loss, as Reported to the Texas Water Development Board Every year the City of Southlake is required to report water loss to the Texas Water Development Board (TWDB). This is non-metered water used in fire hydrant protection, water line flushing for health and safety, and other activities. Water loss also includes water lost to leaks, line breaks, and other uncontrollable flow.

We reported a loss of approximately 17 gallons per water account in 2021. One of the most important tools in accurately measuring water loss and ensuring accurate utility billing is the water meters throughout the City.

The large production meters that measure the incoming water purchased from the City of Fort Worth are tested and calibrated at least once per year. The Southlake Water Utilities’ goal is to conform to the American Water Works Association (AWWA) meter accuracy standard of 98.5% to 101.5%.

Trinity River Authority of Texas Tarrant Water Supply Project In accordance with the requirements of §290.272. Content of the Report. (g)(6) “Systems that use an interconnect or emergency source to augment the drinking water supply during the calendar year of the report must provide the source of the water, the length of time used, an explanation of why it was used, and whom to call for the water quality information.” The City of Fort Worth did not utilize an emergency interconnection in 2021.

The City of Southlake utilized an emergency interconnection with the City of Grapevine, who sources their drinking water from Lake Grapevine and the Trinity River Authority. This emergency interconnection was opened for five and a half hours during Winter Storm Uri in February of 2021 when the City of Forth Worth was unable to supply Southlake with drinking water. For additional questions, please contact the City of Southlake Public Works Department at (817) 748-8082.

Microorganism Testing Shows Low Detections in Raw Water Tarrant Regional Water District monitors the raw water at all intake sites for Cryptosporidium, Giardia Lamblia and viruses. The source is human and animal fecal waste in the watershed.

Viruses are treated through disinfection processes.

The 2021 sampling showed occasional low level detections of Cryptosporidium, Giardia Lamblia and viruses in some but not all of the water supply sources. These are either deactivated or removed through disinfection and/or filtration.

Cryptosporidium and Giardia Lamblia are removed through disinfection and/or filtration.

Viruses are treated through disinfection processes. Cryptosporidium and Giardia Lamblia are removed through disinfection and/or filtration. You may be more vulnerable than the general population to certain microbial contaminants, such as Cryptosporidium, in drinking water. Infants, some elderly, or immuno-compromised persons, such as those undergoing chemotherapy for cancer; those who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care provider. Additional guidelines on appropriate ways to lessen the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline.

Lead and Copper Testing If present, elevated levels of lead can lead to serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and private plumbing.

The City of Southlake is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. If you haven’t turned on any faucets in several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to two minutes before using the water for drinking or cooking. Never use hot water from the tap for cooking or preparing infant formula.

Funny Taste or Smell?

Occasionally, water suppliers experience episodes of unpleasant odors and tastes in the water, often characterized as “earthy” or “musty.” These taste and odor variations are caused by naturally-occurring algae growth in one source of your drinking water, such as Eagle Mountain Lake. The compounds that cause this particular taste and smell do not pose any health risks.

Other constituents, which are often found in drinking water, can also cause taste, color, and odor. These secondary constituents are not causes for health concern. We report information about these secondary constituents to help you understand the cause or source of the taste, odor, and appearance of your water.

These items do not relate to public health but rather to the aesthetic effects. These items are often important to industry.

Unregulated Contaminant Monitoring in 2021 Unregulated contaminants are those for which the EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist the EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. Because these contaminants are not regulated there is not a Maximum Contaminant Level or Maximum Contaminant Level Goal.

Water Pressure & Backflow In any water system, drinking water is transported to homes and businesses through the use of pressure.

Our storage tanks and water lines are tasked with delivering water that is pushed through the system by pumps or, in some cases, the force of gravity. This requires a constant level of pressure to be applied throughout the water system so that water is able to quickly and safely flow from storage to your tap. But what happens when that pressure is lost? Or when pressure on the receiving end of the distribution system increases?

When the pressure of the water system is thrown off, this can lead to a phenomenon known as backflow.

Backflow specifically refers to when an increase of pressure on the supply side or a decrease of pressure on the distribution side of the water line causes water to flow backwards through the water distribution system. When this occurs, it can pose a threat to the health and safety of our drinking water as backflow allows contaminants to enter the water system. Per the City of Southlake Code of Ordinances, Chapter 19, Article VI, the City requires that all commercial establishments install and annually inspect backflow assemblies. These devices on the customer side of the water line prevent backflow from occurring should a change in pressure

take place. Oftentimes, you will find backflow assemblies installed on ice machines, soda fountains, and irrigation systems.

Although the City of Southlake does not require backflow inspections on low hazard connections for residential properties, there is likely an assembly at your home that is connected to your irrigation system. These can only be inspected by a licensed backflow tester who is permitted to conduct work in Southlake. To find a list of backflow testers you can use, please visit www.cityofsouthlake.com/ crossconnection.

In addition to having backflow assemblies tested, there are things you can do at home to prevent backflow from occurring. Keeping these tips and tricks in mind will help ensure our community has clean and safe drinking water: • Do not submerge hoses in water (pools, ponds, buckets, etc.).

• Do not have a chemical sprayer attachment on your hose.

• Do not tie private water sources into the public supply line without adequate backflow protection.

Backflow Prevention The water distribution system is designed to flow oneway from the treatment facility to the home. Backflow prevention protects that one-way flow of clean, safe drinking water from the facility to the home.

Don’t Let Your Future Dry Up

WHY WE PLAN

Projected 92% population increase over the next 50 years

As the population of DFW continues to grow, the demand for water has increased. During Texas summers, water usage across the state rises significantly, which could be detrimental in the face of a drought. The City of Southlake has a Water Conservation Plan and Drought Contingency Plan in place to mitigate the impacts of drought in our community and ensure we are doing our part to conserve this vital resource.

What’s the difference?

The Water Conservation Plan focuses on strategies to reduce the consumption and loss of water as well as improve the use of water. The Drought Contingency Plan is a response plan to address how the system operates under drought conditions, including restriction of water usage. Depending on the current conditions and water supply, the City will issue one of the following stages: • Stage 1: Water Watch • Stage 2: Water Warning • Stage 3: Emergency Water Use Each stage includes mandatory restrictions for residential, commercial, and industrial entities.

The City of Southlake is permanently in Stage 1, as adopted and enforced by Ordinance Number 662.

What activates the Drought Contingency response stages?

There are a set of triggers that need to be met before the City Manager can order drought response.

These include the storage tank and reservoir levels, water demand, delivery capacity, and water treatment or distribution complications. Since Southlake receives water from the City of Fort Worth and Tarrant Regional Water District, any stages imposed by these authorities must also be initiated in Southlake.

Water demand is projected to increase 67%

Texas’ existing water supplies are expected to decline 3%

What can you do?

With summer in full swing, there are several things you can do to ensure that we as a community are doing our part to conserve water.

Follow the City of Southlake’s irrigation guidelines.

Based on what stage of the Drought Contingency Plan we are in and your home address, the City of Southlake will issue irrigation guidelines that lay out which days of the week and times you are permitted to irrigate. Because irrigation is one of the largest contributors to water waste, these watering restrictions play a big part in helping us save water.

Modify your bathroom habits. Instead of taking a bath, why not opt for a short shower instead?

Or, when brushing your teeth, be sure to turn the faucet off instead of letting the water run. These seemingly small changes in your routine can help save hundreds of gallons of water each year!

Check for leaks and excess water use. Oftentimes, faulty pipes and leaks in your home can go unnoticed. One of the best ways to identify those hidden leaks is to sign-up for an EyeOnWater account. This free website gives you real-time insights on your water consumption and will notify you if there are any unusual spikes in water use that may be caused by a leak. Additionally, having an EyeOnWater account gives you access to our W.I.S.E. Guys program, where you can request a free sprinkler evaluation and receive up to $200 off your next water bill!

Let’s Talk About It As the summer heat hits Southlake, remember to follow your watering schedule! Residents, businesses, and Homeowner Associations must only water on their designated days and between the hours of 6:00pm and 10:00am.
