CWB - Water Quality Report

Dear Customer,

This annual report on the quality of your drinking water is our record of accountability to you. We have tried to provide this information in a clear and easy-to-read format while being sensitive to cost. We are proud to report that our water meets or exceeds all state and federal standards.

Why am I receiving this report?

In compliance with the Safe Drinking Water Act Amendments, the Clarksburg Water Board 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, 2010, or other test results if test period is not on a yearly cycle. If you have any questions concerning this report, you may contact our lab at 304-624-5467 ext. 122.

If you have any further questions, comments or suggestions, please attend any of our regularly scheduled Board Meetings held on the 2nd and 4th Tuesday of each month at 2:30 P.M. at the Clarksburg Water Board Office in Clarksburg, WV at 1001 S. Chestnut St.

Where does my water come from?

Your water source is surface water from the West Fork River.

Source Water Assessment

The intake that supplies drinking water to the Clarksburg Water Board has a higher susceptibility to contamination, due to the sensitive nature of surface 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 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 at our office or from the West Virginia Bureau for Public Health (WVBPH) 304558-2981.

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, 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 activities. 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 (800-4264791).

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.

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

pCi/l – picocuries per liter

NE – not established

NA – not applicable

The Clarksburg Water Board conducted monitoring of contaminants included in the Unregulated Contaminant Monitoring Rules I (2002) and II (2010) issued by the US Environmental Protection Agency and we are happy to report that there were no detections for any of the parameters where monitoring was required under this Rule. The data from this monitoring is available for review by contacting the Clarksburg Water Board Laboratory at 304-624-5467, ext. 122.

* – 30 Lead and copper samples taken from the distribution system June 2010, next samples due 2013. Results listed are the 90th percentile, no samples exceeded MCL .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 Clarksburg Water Board 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 at 1-800-426-4791 or at http://www.epa.gov/safewater/lead

Additional Information

In 2010 we conducted monitoring of numerous other contaminants and we are proud to report that there were no detection of these. Data for these are also available.

Sodium is an unregulated contaminant. Anyone having a concern should contact their primary health care provider.

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

Our water system violated drinking water monitoring requirements within the past year. Even though these were not emergencies, you, as our customers, have to know what happened and what we did to correct the situation. We are required to monitor your drinking water on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During 1/1/2008 to 12/31/2010, we monitor for Synthetic Organics only one time and we did not test for the second sample as required and therefore cannot be sure of the quality of our drinking water during that time. There is nothing you need to do at this time. The result of the first sample was no detections. This violation type code is routine minor. We have taken corrective actions to monitor all required samples. This notice is being sent to you by: Clarksburg Water Board, state water system ID # WV 3301705.
