Why Am I Receiving This Report?
In compliance with the Safe Drinking Water Act Amendments, the Town of Davis 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, 2014, or earlier if not on a yearly schedule.
If you have any questions concerning this report, you may contact Robin Cousin, Chief Operator, Monday through Friday (8:00 a.m. to 4:00 p.m.) at 304-259-5502. If you have any further questions, comments, or suggestions, please attend any of our regularly scheduled water board meetings held on the 2nd and 4th Wednesday of every month at 6:30 p.m. in the Davis Town Hall, Davis, WV.
Where does my water come from?
Your drinking water source is surface water from the Weimer Run and Blackwater Rivers.
Source Water Assessment
A Source Water Assessment was conducted in 2003 by the West Virginia Bureau for Public Health (WVBPH). The intake that supplies drinking water to the Town of Davis 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 your review and/or a copy can 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 for 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.
• TT – Treatment Technique, or a required process intended to reduce the level of a contaminant in drinking water.
Abbreviations that may be found in the table:
• ppm – parts per million or milligrams per liter
• ppb – parts per billion or micrograms per liter
• NTU – Nephelometric Turbidity Unit, used to measure cloudiness in water
• NE – not established
• N/A – not applicable
The Town of Davis routinely monitors for contaminants in your drinking water according to federal and state laws. The tables below show the results of our monitoring for contaminants.

We are pleased to report that the Town of Davis Water Company met all federal and state water standards for 2014.
The Town of Davis has also monitored for some 33 other contaminants and none were found to have detects.
Additional Information
All other water test results for the reporting year 2014 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 filtration system.
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 Town of Davis 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 Water Hotline or at http://www.epa.gov/safewater/lead.
This report will not be mailed. A copy will be provided to you for your use upon request at out office during regular business hours. Please call first so that a copy may be prepared for you.
