Why Am I Receiving This Report?
In compliance with the Safe Drinking Water Act Amendments, the Lewisburg Municipal Water System is providing its customers with this annual water quality report. This report explains where your water comes from, what it contains, and how it compares to standards set by regulatory agencies. The information in this report shows the results of our monitoring for the period of January 1st to December 31st, 2017, or earlier if not on a yearly schedule.
If you have any questions concerning this report, you may contact Roger Pence, Public Works Director, 304-645-1833. If you have any further questions, comments or suggestions, please attend any of our regularly scheduled water board meetings held on the 3rd Tuesday of every month at 7:30 P.M. in the Paul R. Cooley Council Chamber, City Hall, Lewisburg, WV.

Where does my water come from?
Your drinking water source is surface water from the Greenbrier River.

Source Water Assessment
A Source Water Assessment was conducted by the West Virginia Bureau for Public Health (WVBPH). The intake that supplies drinking water to the Lewisburg Municipal Water System has a higher susceptibility to contamination, due to the sensitive nature of surface water supplies and the potential contaminant sources identified within the area. This does not mean that this intake will become contaminated; only that conditions are such that the surface water could be impacted by a potential contaminant source. Future contamination may be avoided by implementing protective measures. The source water assessment report which contains more information is available for review or a copy will be provided to you at our office during business hours or from the WVBPH 304-558-2981.

Why must water be treated?
All drinking water contains various amounts and kinds of contaminants. Federal and state regulations establish limits, controls and treatment practices to minimize these contaminants and to reduce any subsequent health effects.

Contaminants in Water:
In order to ensure that tap water is safe to drink, the EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits of contaminants in bottled water which must provide the same protection tor public health.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of these contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
The source of drinking water (both tap and bottled water) includes rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of land or through the ground, it dissolves naturally-occurring minerals, and, in some cases radioactive material and can pick up substances resulting from the presence of animals or from human activity.

Contaminants that may be present in source water include:
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 storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, farming.
Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water 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 storm water runoff, and septic systems.
Radioactive contaminants, which can be naturally-occurring or the result of oil and gas production and mining activities.
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 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 microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

Water Quality Data Table
Definitions of terms and abbreviations used in the table or report:
• MCLG – Maximum Contaminant Level Goal, or 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.
• MCL – Maximum Contaminant Level, or the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technique.
• MRDLG – Maximum Residual Disinfectant Level Goal, or the level of drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect benefits of use of disinfectants to control microbial contaminants.
• MRDL – Maximum Residual Disinfectant Level, or the highest level of disinfectant allowed in drinking water. There is convincing evidence that the addition of disinfectant is necessary to control microbial contaminants.
• AL- Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.
Abbreviations that may be found in the table:
• ppm – parts per million or milligrams per liter
• ppb – parts per billion or micrograms per liter
• NA – not applicable
• NE – not established
• NTU – Nephelometric Turbidity Unit, used to measure cloudiness in water
The Lewisburg Municipal Water System routinely monitors tor contaminants in your drinking water according to federal and state laws. The tables below show the results of our monitoring for different contaminants.

*Copper and lead samples were collected from 20 area residences on August 25, 2016. None exceeded the MCL. Only the 90th percentile values are shown.
**For the reporting year 2017 we received several “Notice of Violation” letters from the WV Bureau for Public Health for an exceedance of the MCL with our haloacetric acids samples. We have made every effort and taken every precaution to return to compliance.
Some people who drink water containing haloacetic acids in excess of the MCL over many years may have an increased risk of getting cancer.
Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or nervous system, and may have an increased risk of getting cancer.

Additional Information

All other water test results for the reporting year 2017 were all non-detects.

Turbidity is a measure of the cloudiness in water. We monitor it because it is a good indicator of the effectiveness of our filters.

If present, elevated levels of lead can cause 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 home plumbing. The Lewisburg Municipal Water System 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 for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your drinking water, you may wish to have your water tested. 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.
