Quality water begins at the source. It is important that the Western Virginia Water 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.

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. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Copper is a nutritionally essential element, but at high levels, copper can cause gastrointestinal difficulties such as nausea and diarrhea. Elevated levels of lead, if present, can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily associated with materials and components in service lines and home plumbing.

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 Authority maintains over 1500 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.

How are the standards set?

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-onemillion chance of having the described health effect for other contaminants.

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.

The Western Virginia Water Authority is responsible for providing high quality drinking water but cannot control the variety of materials used in plumbing components. When your water has been sitting in your pipes for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes or until it becomes cold or reaches a steady temperature before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested.

The tables of data on pages 8-38 summarize water-testing results from 2016 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. 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, 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.

Testing Your Water

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.

Spring Hollow Reservoir

Cryptosporidium & 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 Cryptosporidium and Giardia. Giardia, 0.2 cyst per 1 liter, was detected in the raw (untreated) water at Falling Creek in March 2016. Cryptosporidium was detected in the raw (untreated) water at Carvins Cove (0.1 cyst per 1 liter in January 2016 and 0.1 cyst per 1 liter in February 2016).

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 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).

Commonly Asked Questions

Terms used in this water quality report

What is my Water Hardness?

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.

What Causes 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.

Action Level (AL): The concentration of a contaminant that triggers treatment or other requirement that a water system must follow.

Combined Radium: Radium 226 + Radium 228 E. coli: Bacteria from human and animal fecal waste HAA5s: Haloacetic acids.

LRAA: Locational Running Annual Average Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLG as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Maximum Residual Disinfection Level (MRDL): The highest level of a disinfection allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. mg/L: Milligrams per liter, also referred to as parts per million (for example, one minute in two years).

Water Quality Testing

Substance

ND: Analyte was not detected or was below the method detection limit of the laboratory’s instrumentation.

NTUs: Nephelometric Turbidity Units; a measure of turbidity.

P/A: Present or Absent pCi/L: Picocuries per liter is a measure of the radioactivity in water. ppm: One part per million, also referred to as mg/L, (for example, one minute in two years). ppb: One part per billion, also referred to as μg/L (for example, one minute in 2,000 years).

TTHMs: Total Trihalomethanes Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water. μg/L: Micrograms per liter, also referred to as parts per billion (for example, one minute in 2,000 years). μmhos/cm: Micromhos per centimeter; a measure of conductivity.

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 853.5700.

Through 2016, 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 High Point Water Treatment Plant to the Westlake area via the Westlake Area Water System. A new 3 MGD jointly owned and operated microfiltration treatment facility opened in May 2017 that will replace the High Point Facility.

How is it treated? The membrane filtration facility treats water from Smith Mountain Lake. The WVWA’s share of the current plant’s capacity is 400,000 gallons per day (gpd). The finished water in the distribution system is re-chlorinated at The Boardwalk and at The Waterfront Section 2-9 subdivisions 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 WVWA’s service area. Customers who live in the Westlake Commercial District, Chestnut Creek, Waterfront, Boardwalk

24

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 is pleased to report that this water meets all requirements, and there were no drinking water violations in calendar year 2016.

about your water

Classroom Presentations

Tours of our treatment facilities and reservoirs are offered for students, civic and community groups.

You will be amazed to learn what goes on behind the faucet as we treat and deliver the highest quality drinking water to our customers.

Guest Speakers

To request a visit, please call 853.5700 or email education@westernvawater.org

We’d love to show you how we treat your water.

Interested in having a speaker talk to your civic league or community group? We’d be happy to talk to your group about your water source, how we treat your water and improvements we are making to the water and wastewater infrastructure. Contact us at info@westernvawater.org for scheduling and information.

Research The Western Virginia Water Authority has partnered with Virginia Tech researchers and graduate students

since the 1990s to lead water quality research projects on the Authority’s drinking water reservoirs. This partnership trains graduate students with real-world experiences while providing valuable data for management. Students inform reservoir management of oxygenation, discharge rates, water chemistry and more. As a result of the research, oxygen is now fed into the reservoirs to keep naturally occurring iron and manganese locked in the sediment layers, saving the expense of chemical addition in the treatment facilities. Algal blooms are also reduced as a result of the increased oxygen because it locks up nitrogen and phosphorus, essential components of algae growth, in the reservoir sediments. Through this Virginia Tech partnership, the Western Virginia Water Authority has the strongest track record of water quality monitoring of any Virginia utility.

Source Water Protection

28

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;

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

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

Help us identify potential locations where backflow can occur.

You can complete a simple Backflow Prevention Survey on-line at www.westernvawater.org.

• 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

If necessary, contact the Water Authority to schedule a free assessment with our staff to assist you in finding and removing any potential cross-connection sources.

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

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.

Questions about backflow prevention? email us at backflow@westernvawater.org call us at 853.5700

We all need to work together to protect our drinking water.

The Western Virginia Water Authority and all our customers share the responsibility to help safeguard the public water supply. We are working closely with the Virginia Department of Health and our customers to identify potential backflow issues so your drinking water maintains the highest possible quality.

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

• Fix leaks in faucets, toilet tanks and outside spigots. Check for a toilet leak by putting some food coloring in your toilet tank. The next morning, if any of the color shows up in the bowl without flushing, you have a leak. A leaky toilet can waste up to 200 gallons of water per day.

• In the laundry or kitchen, use full loads in your washing machine and dishwasher to maximize efficiency.

• Don’t overwater your lawn. If you water your lawn, it only needs 1 to 1.5 inches of water every week or two. Water your garden or lawn before 10 AM or after 7 PM when temperatures are cooler to minimize evaporation.

• While brushing your teeth, turn off the water and save two gallons of water.

• Taking shorter showers saves water. Shorten your shower to five minutes.

• Have a leak? Fix it and let us know right away. If your meter records a continuous high flow of consumption, we’ll notify you about a potential leak.
