Western Virginia Water Authority Drinking Water Report (CCR) 2025 by Western Virginia Water Authority

WESTERN VIRGINIA WATER AUTHORITY

ABOUT THIS REPORT

The Western Virginia Water Authority supplies customers in the City of Roanoke, the Counties of Roanoke, Franklin and Botetourt and the Towns of Boones Mill and Vinton, VA with an annual water quality report. This provides you with information about the source of your water, what it contains and how it compares to the standards set by regulatory agencies based on data collected during calendar year 2024 or the most recent testing period.

On July 1, 2004 the Western Virginia Water Authority was formed from the former utility departments of the City of Roanoke and Roanoke County. In November 2009 Franklin County joined the Water Authority, and Botetourt County joined in 2015 offering a larger regional approach to meeting the communities’ water and wastewater needs. The Town of Boones Mill started receiving service from the Water Authority in 2021, and the Town of Vinton utility system was acquired in 2022. In 2024, the Authority began operations of the Ferrum Sewer & Water Authority.

OUR EXECUTIVE DIRECTOR

Michael McEvoy, the Western Virginia Water Authority’s Executive Director, oversees a dedicated team of professionals who enhance the well-being and quality of life for our regional community through the treatment and delivery of 19-million gallons of drinking water and collection and treatment of 32-million gallons of wastewater each day.

Over our 20-years of operation, the Authority has earned the highest industry awards for both water and wastewater, implemented energy saving measures across all departments, and rehabilitated aging water distribution and sewer collection pipes. Water is treated from surface water and groundwater sources located across the service area.

BOARD OF DIRECTORS

The Western Virginia Water Authority’s Board of Directors, appointed by the member localities, governs the Authority. Representatives from the City of Roanoke include Mr. Harvey Brookins, Mr. Mike Loveman and Ms. Valmarie Turner. The Roanoke County representatives include Mr. Don Halliwill, Mr. Richard Caywood and Mr. Randall Hancock. Mrs. Shirley Holland represents Franklin County, and Mr. Hunter Young represents Botetourt County.

Board meetings are held on the third Thursday of each month (with the exception of August and December) at 601 S. Jefferson Street. The Board meetings are open to the public, and meeting minutes and information is available on our website at www.westernvawater.org.

Setting Standards for Your Water

In order to ensure that tap water is safe to drink, the Environmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. That informaton is provided in the data charts on pages for 7 - 43 for each water system.

Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health. All drinking water, including bottled drinking water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk.

The U.S. Environmental Protection Agency (EPA) sets maximum contaminant levels (MCLs) at very stringent levels. In developing the standards, EPA assumes that the average adult drinks 2 liters of water each day throughout a 70-year life span. EPA generally sets MCLs at levels that will result in no adverse health effects for some contaminants or a one-in-ten-thousand to one-in-one-million chance of having the described health effect for other contaminants.

Cryptosporidium and Giardia

Cryptosporidium and Giardia are microscopic organisms that can cause fever, diarrhea and other gastrointestinal symptoms when ingested. The organisms come from animal and human wastes and are eliminated through water filtration and disinfection. Even though the presence of these organisms is not regulated by the state or federal government, the Water Authority has tested for these organisms.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing chemotherapy, persons

The tables of data on pages 7 - 43 summarize water-testing results from 2024 or the most recent reporting year for both regulated and non-regulated substances. Many other primary and secondary contaminants have been analyzed but were either below the instrument’s detection limits or below the MCLs.

There is no State or Federal MCL for sodium. Monitoring is required to provide information to consumers and health officials that are concerned about sodium intake due to dietary restrictions. The EPA recommended optimal level of sodium is less than 20 ppm, established for people on a “strict” sodium intake diet. The amount of sodium detected in each water system is listed in the data charts.

The Western Virginia Water Authority constantly monitors its water supplies for various contaminants to meet all regulatory requirements. All regulated substances must be tested annually (or triennially for small systems) except for lead and copper and SOCs, which must be tested every three years, and radiologicals, which must be tested every six to nine years. The TTHMs/HAA5s were derived from running annual averages.

who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/ CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

Water Hardness Discolored Water

Changes in water pressure in water systems, such as when water mains break or fire hydrants are used or flushed, can occasionally cause drinking water to be discolored. The discoloration is caused by sediments in pipes mixing with clear water. The sediments occur naturally from the oxidation of iron in pipes.

While discolored water is ordinarily safe to drink, it is best to flush any discolored water from pipes by turning on all cold-water faucets in your home or business. Avoid turning on hot-water faucets so the discolored water is not drawn into water heaters.

If you notice evidence of a water main break or leaking fire hydrant, please call 540.853.5700.

As water naturally flows over rocks and through the soil, it picks up minerals. The more calcium and magnesium present, the harder your water. While water hardness is not a safety issue, you may notice increased mineral build-up or soap residue with harder water. Hardness can be expressed as PPM - parts per million or GPG - grains per gallon.

Lead and Copper Testing

Quality water begins at the source. It is important that the Western Virginia Water Authority (Authority) knows and understands the water chemistry from each source, closely monitors the treatment process and understands the pipe material that the water can flow through. This is especially important regarding lead and copper.

Copper is a nutritionally essential element, but at high levels, copper can cause gastrointestinal difficulties such as nausea and diarrhea. Lead can cause serious health problems, especially for pregnant women and young children. Exposure to lead in drinking water can cause serious health effects in all age groups. Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new learning and behavior problems or exacerbate existing learning and behavior problems. The children of women who are exposed to lead before or during pregnancy can have increased risk of these adverse health effects. Adults can have increased risks of heart disease, high blood pressure, kidney or nervous system problems.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The Western Virginia Water Authority is responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of materials used in plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by

identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact the Authority at 540.853.5700. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/safewater/lead

The Authority maintains over 1,300 miles of pipes up to and including the lines going to the customer’s water meter. Pipe materials in our system can be cast iron, ductile iron or pvc. We do not know of any lead pipes in our distribution system. However, customers, particularly those in older homes, may have lead plumbing in their homes or pipes that were joined with lead solder.

We treat the water with corrosion control or adjust the pH of the water so that pipes in our distribution system and the customers’ pipes in their homes are protected.

Information on lead in drinking water, testing methods and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead

What is Your Service Line Pipe Material?

The Water Authority has developed an inventory of service line pipe material used in our public distribution system and in the customer’s pipe from the meter to the home. This is a requirement of the Environmental Protection Agency’s Lead and Copper Rule Revision. You can view the Water Service Line Lead Status dashboard at www. westernvawater.org/gis

While no lead lines have been found on the public side, we need your help identifying what type of pipe material is coming into your home.

Water service line pipes can consist of many different materials including lead, galvanized iron, brass, copper or plastic. Use this information or scan the QR code below to watch our video tutorial to help you determine your water service line material and/or plumbing material.

We’re asking customers to enter their water service line pipe material on our reporting form so we can add it to the Authority’s GIS mapping and inventory.

For properties where the inventory has already been obtained, you will see the type of pipe material that comes from the public water line to your meter and any information we have on the private water line that comes from the meter to your home.

Unregulated Contaminant Monitoring - UCMR5

The following substances were tested in Western Virginia Water Authority sources during calendar year 2023-24 as part of the unregulated contaminants monitoring. Unregulated contaminants are those for which EPA has not established drinking water standards. The unit of measurement for all data is ng/L.

Unregulated contaminant monitoring helps EPA to determine where certain contaminants occur and whether the Agency should consider regulating those contaminants in the future.

Spring Hollow was tested four times in this monitoring period - 9/11/23, 12/13/23, 3/28,23, and 6/11/24. The only detections were 9/11/23.

Crystal Spring was tested five times in this monitoring period - 9/11/23, 12/13/23, 3/29/,24, 4/3/24 and 6/11/24. There were no detections.

Muse Spring Treatment Plant was tested four times in this monitoring period9/11/23, 12/13/23, 3/28/,24, 6/11/24 and 6/11/24. One detection was made on 3/28/24.

Source Water Assessment

As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and can pick up substances resulting from the presence of animals or from human activity. Water from surface sources is treated to make it drinkable while groundwater may or may not require any treatment.

Contaminants in source water may be naturally occurring substances, or may come from:

• Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife;

• Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming;

• Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses;

• Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems; and

• Radioactive contaminants, which can be naturallyoccurring or be the result of oil and gas production and mining activities.

The assessment determined that Crystal Spring, Muse Spring and Carvins Cove are susceptible to contamination based on land use activities and potential types of contaminants in these areas. This designation does not mean that the source water has been impacted or that it will be impacted. It does mean that if there is a release of pollutants in the assessment area, the source water could be impacted.

The VDH also completed a source water assessment of Spring Hollow Reservoir’s water source, the Roanoke River. This assessment determined that the Roanoke River may be susceptible to contamination because it is surface water exposed to a wide array of contaminants at varying concentrations. Also, changing hydrologic, hydraulic and atmospheric conditions promote migration of contaminants from land use activities of concern.

The assessment also determined that the Water Authority’s wells might be susceptible to contamination because they are located in areas that promote migration of contaminants from land use activities of concern. More specific information about these reports may be obtained by contacting the Western Virginia Water Authority’s Water Quality Division at 540.853.5700.

Backflow Prevention & Cross-Connection Identification

A plumbing cross-connection is an actual or potential connection between the public water supply and any source of contamination or pollutant. Without proper plumbing precautions, contaminated substances could backflow into the public system and your drinking water supply through this connection.

Water travelling through the Authority’s distribution system is pressurized. If the water system loses pressure, such as during a water main break, system maintenance or fire hydrant usage/testing, the flow of the water may be reversed. If a customer has made a cross-connection with hazardous substances or even non potable water, these substances can backflow into the public water system and create a risk to public health.

What You Can Do To Protect Your Drinking Water

Help us identify potential locations where backflow can occur.

Remove any cross-connections you find or install backflow prevention devices (available at hardware stores) where needed. A Water Authority representative is available to assist you with this process if needed.

If you have a backflow prevention device installed by a certified plumber, have it tested annually or after any repairs.

Use Your Water Wisely

Using water wisely in times of drought is critical; however, it is always important to use our natural resource wisely.

SHOWERS

Shorten your shower to 5 minutes and save up to 25 gallons of water.

LEAKS

Fix a leaky faucet and save up to 140 gallons of water a week.

WATERING YOUR LAWN

Put an empty tuna can on the lawn to catch and measure the output of your sprinkler. When the can is full, it’s time to turn off the sprinkler.

LAWN CARE

Water your garden or lawn before 10 AM or after 7 PM when temperatures are cooler to minimize evaporation.

BRUSHING YOUR TEETH

Turn off the water while you brush your teeth and save 2 gallons of water.

LAUNDRY & DISHES

Use full loads in your washing machine and dishwasher to maximize efficiency.

WATERING PLANTS

Use old water from your dog’s bowl, leftover water from rinsing vegetables or the warm-up water from your shower to water plants.

CAR WASHING

Instead of washing your car at home, take it to a commercial car wash that recycles its water.

How to Check for a Toilet Leak

Toilets are the number one source of water leaks inside the home so this is the best place to start a leak detection. Because a toilet leak can waste up to 200 gallons of water per day, it is important to regularly test your toilets and quickly repair any leaks you discover.

To determine if a toilet is leaking, place some dye such as food coloring, Kool-Aid, cola or brewed coffee in the tank of the toilet before you go to bed. Do not flush or use the toilet during the test. If you see any of the color in the bowl of the toilet the next morning, then you know you have a leak that needs to be repaired.

If you discover that you have a toilet leak, make sure the lift chain is free of kinks and that you don’t have any mineral buildup around your valves that might prevent them from sealing properly. You can also use the adjustment screw on the overflow pipe to lower the water level in the tank to keep it from flowing into the overflow pipe. Most overflow pipes have a line on the pipe that indicates where the water level needs to be. If the flapper valve or plunger ball isn’t properly sealing at the bottom of the toilet, you will also get leaks. Parts are available at your local hardware store to replace these items.

Drinking Water Systems in the Roanoke Valley

The Western Virginia Water Authority utilizes four surface water sources and multiple springs and wells as drinking water sources in the Roanoke Valley to serve customers in the City of Roanoke, the Counties of Roanoke, Franklin and Botetourt and the Towns of Boones Mill and Vinton. Having an abundant supply of water helps protect against drought or other emergencies.

Combined, the water treatment facilities for these sources can treat over 56-million gallons of water a day; however, current production averages about 19-million gallons per day.

Carvins Cove Reservoir & Treatment Facility

Carvins Cove Reservoir is situated within Carvins Cove Natural Reserve, a 12,672-acre watershed near Hollins University in Botetourt County. The land in the reserve above the 1,200-foot contour is owned and managed by the City of Roanoke. The land below this elevation, and the reservoir, are owned and operated by the Western Virginia Water Authority. In addition to receiving water from the watershed, the reservoir is fed from two underground tunnels that carry overflow from Tinker and Catawba Creeks. This surface water source covers 630 acres and stores 6.42-billion gallons of water at full pond.

How is it treated? Carvins Cove Water Treatment Facility has the capacity to treat 24-million gallons of water from the reservoir every day. Annual production averaged 9.48-million gallons per day. The water is first oxygenated and treated with sodium permanganate to oxidize dissolved organic matter, iron and manganese. Water is aerated to remove unwanted dissolved gases and to oxidize dissolved metals, which reduces any unpleasant tastes and odors. Flash mixing of chemicals is the next step, where ferric sulfate is added to coagulate suspended particles. Water then flows into settling basins where the particles clump together, become heavy and settle to the bottom of the basins. Next, the water is filtered through sand and anthracite and disinfected with chlorine. Fluoride is added to promote strong teeth. Sodium hydroxide is added to adjust the pH and reduce corrosivity, and orthophosphate is added to control corrosion in pipes.

Where does it serve? A large part of the northeastern and northwestern parts of the city, and the majority of the southeastern part of the city, to Reserve Avenue, are served by Carvins Cove. Portions of northern and northeastern Roanoke County are also served by the Carvins Cove water source. Water from Carvins Cove also serves the Botetourt area around Exit 150 to Tinkerview and Greenfield.

The Water Authority has inventoried service line pipe material, and has not found any lead lines to date. You can view the Water Service Line Lead Status dashboard at www.westernvawater.org/gis

Many other primary and secondary contaminants have been analyzed but were either below the instrument’s detection limits or below the Maxium Contaminant Levels (MCLs). Data collected during calendar year 2024 or most recent testing period. Water treated at the Carvins Cove Treatment Facility meets all state and federal monitoring and reporting requirements.

Carvins Cove Natural Reserve

Spring Hollow Water Treatment Facility

The water source for this system comes from the Roanoke River and is pumped into the Spring Hollow Reservoir, a 3.2-billion gallon sidestream storage reservoir.

How is it treated? Water is first oxygenated in the reservoir, then the water is withdrawn from the reservoir and treated with sodium hypochlorite and sodium permanganate to oxidize dissolved organic matter, iron and manganese. Treatment at the Spring Hollow Treatment Facility includes upflow clarification, filtration, chlorine disinfection and fluoridation. Orthophosphate is added to control corrosion in pipes. The Spring Hollow Water Treatment Facility currently has the capacity to treat 18-million gallons of water a day and can be expanded to 36-million gallons a day. Treated water is stored in a two-million gallon storage tank then pumped through the north and south transmission lines to the distribution system. Annual production averaged 3.42-million gallons a day. During an emergency, standby wells may be used to supplement the source water.

Where does it serve? Spring Hollow supplies water to various neighborhoods in Roanoke County and Franklin County through the southern transmission lines. The northern transmission lines run along I-81 and serve the City of Roanoke and Roanoke County.

Many other primary and secondary contaminants have been analyzed but were either below the instrument’s detection limits or below the MCLs.

Learn About PFAS

PFAS are a group of over 6,000 man-made compounds used in various industries around the globe since the 1940s to make everyday products we use resist heat, oil, stains, grease, and water. They are extremely stable and do not breakdown in the environment.

The Western Virginia Water Authority (Authority) voluntarily tested for these substances as part of the unregulated contaminants monitoring program. Hexafluoropropylene oxide dimer acid (HFPO-DA), known more commonly by its trade name GenX, was detected at Spring Hollow. All other compounds were below the level of detection. At the time of this testing, there were no national or state advisories or

regulations for HFPO-DA. Testing continued as did research into the source of this substance.

On June 15, 2022, the EPA issued a lifetime health advisory for HFPO-DA of 10 parts per trillion (ppt) for the first time. For reference, if expressed as a unit of time, one part per trillion would be approximately one second in 32,000 years. On March 14, 2023 the EPA announced the proposed National Primary Drinking Water Regulation (NPDWR). This rule proposed that 10 parts per trillion would effectively become the maximum contaminant level for HFPO-DA. The proposed PFAS NPDWR did not require any actions until it became final. On April 10, 2024, the rule was finalized with the release of the final National Primary Drinking Water Regulation (NPDWR). In addition to establishing Maximum Contaminant Levels for several PFAS compounds, 10 parts per trillion was established as the maximum contaminant level for HFPO-DA, the compound detected at the Spring Hollow Reservoir. UCMR5 testing by the Virginia Department of Health in 2023 indicated detection of a second compound, PFOA, in the amount of 8.9 ppt. Weekly tests in 2024 have been non-detect for that compound in the Spring Hollow Reservoir and treated drinking water.

After the detection of HFPO-DA in the Spring Hollow Reservoir, the Authority increased the frequency of testing for this compound at Spring Hollow and adapted the use of granular activated carbon, considered the most viable treatment option for drinking water, as a treatment technique. The granular activated carbon is replaced every three months to provide optimal treatment to produce drinking water that is has HFPO-DA levels below 10 parts per trillion. The HFPO-DA detection level during calendar year 2024 from weekly testing was 0.615 ppt.

Pumping water from the Roanoke River was suspended from August 2022 to July 2023 to avoid introducing any more of the compound into the reservoir. The source of HFPO-DA in the Roanoke River, ProChem, Inc. in Elliston, Virginia stopped discharging water containing this compound and repeat tests determined that the river has remained non-detect for HFPO-DA since May 2023.

January 1st to December 31st, 2024 or the most recent monitoring period. The City of Salem Water Department had no violations during this time period. The Virginia Department of Health has completed a source water assessment for Salem’s waterworks system that provides information on possible sources of contamination to the source water. As determined by the source water assessment, the possibility of contamination to this water source (Roanoke River) is high. This is due to the fact that surface water is exposed to an inconsistent array of contaminants at varying concentrations due to changing hydrologic, hydraulic and atmospheric conditions with land use activities of concern in the assessment area. To view a copy of this water assessment, please contact the City of Salem Water Department office at 540-375-3029.

Smith Mountain Lake Water Treatment FacilityWestlake Area Water System

The Western Virginia Water Authority (WVWA) has a successful working relationship with the Bedford Regional Water Authority (BRWA) to provide treated drinking water from the Smith Mountain Lake Water Treatment Plant to customers in the Westlake Area Water System area. This facility, which opened in May 2017, was designed to meet both utilities’ joint water needs through the year 2060 as recommended by the Regional Long Range Water Supply Plan.

How is it treated? Water from Smith Mountain Lake is screened through 500 micron woven mesh stainless steel strainers to remove fine silt and then pumped to the treatment facility. The membrane plant has 216 modules that each have 10,000 membrane filter strands to provide the unique water treatment capability. The membranes can filter out particles larger than 0.02 microns. Ferric sulfate and permanganate is added as a coagulation. After filtration, the water is treated with sodium hypochlorite, a required disinfectant to eliminate bacteria. The finished water in the distribution system is re-chlorinated at The Boardwalk, The Waterfront Section 2-9 subdivisions and at Burnt Chimney for continuous chlorination.

Where does it serve? Water from this treatment plant serves customers in Bedford County and Franklin County. As the water flows through pipes under Hales Ford Bridge, it enters the Westlake Area Water System service area. Customers in the Westlake Commercial District, Boardwalk, Chestnut Creek, Compass Cove, Deer Creek, Hales Point, Lakewood Forest, Long Island, StarOverLake, Striper’s Landing, Twin Cove, Waterfront, Waverly, Weatherwood and Windmere Point communities, along Scruggs Road and along Route 122 to just past Wirtz Road are served by the Westlake Area Public Water System.

The Western Virginia Water Authority and Bedford Regional Water Authority are pleased to report that this water meets all requirements, and there were no drinking water violations in calendar year 2024.

A source water assessment for the Westlake Area systems has been conducted by the Virginia Department of Health. Well(s) serving this community were determined to be of high susceptibility to contamination using the criteria developed by the state in its approved Source Water Assessment Program. The assessment report consists of maps showing the source water assessment area, an inventory of known land use activities of concern and documentation of any known contamination within the last five years. The assessment determined that this source might be susceptible to contamination because they are located in areas that promote migration of

The Retreat |

Groundwater from wells located in Lake Forest and The Retreat is pumped to The Retreat where pre-treatment of the water includes the addition of potassium permanganate and sodium hypochlorite solutions, and greensand filters are used to remove iron and manganese from the drinking water. Once the water is filtered and disinfected, it is introduced into the interconnected distribution system providing potable water to Cedar Ridge, Lake Forest, The Coves and The Retreat.

The Retreat Water System found elevated levels of lead in drinking water in some homes/buildings. The Authority collected routine lead and copper samples taken from internal residential faucets during the JuneSeptember 2023 monitoring period as required by the Virginia Department of Health. Results from those samples showed that two of the eight sample locations had a concentration of lead above the EPA Action Level. The EPA Action Level for lead is 0.015 mg/L. The results of the samples were 0.0167 mg/L for lead. The other six sample locations were less than 0.005 mg/L. The homeowners whose internal faucet sample results were above the Action Level were directly notified by the Authority. Required information was mailed to residents on February 19, 2024. However, these materials were required to be delivered by November 30, 2023, and we did not meet that deadline.
