CCR-Riner-2012.pdf2012 This report is designed to inform you about your drinking water quality. Our goal is to provide a safe and dependable supply of drink- ing water. We want you to understand the efforts we make to protect your water supply. The quality of your drinking water must meet state and federal require- ments administered by the Virginia Department of Health (VDH). The Montgomery County Public Service Authority (PSA) operates ten individual public water systems in the unincorpo- rated areas of the County. Combined, these systems consist of almost 100 miles of water mains, four wells, 16 water tanks, 22 pumps, 24 pressure reducing valves, four connections to the Town of Blacksburg, three connections to the Town of Christiansburg, two connections to the City of Radford, and one connection to the Arsenal. Approximately 25.5 million gallons of water are distrib- uted by the PSA monthly. If you have questions Monday of each month in the County Administration Conference Room in the Montgomery County Government Center, 755 Roanoke Street in Christiansburg.

(2) Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, indus- trial or domestic wastewater discharges, oil and gas produc- tion, mining, or farming. (3) Pesticides and herbicides, which may come from a variety of sources such as agriculture, ur- ban storm water runoff, and residential uses.

NDNDNDND Not DetectedNot DetectedNot DetectedNot Detected Lab analysis indicates that the contaminant is not present or is below detection limit Additional health information for lead 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 Montgomery County Public Service 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 for several hours, you can minimize the potential for lead exposure by flush- ing your tap for 15 to 30 seconds 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. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Water Drinking Hotline (800-426-4791) or at http://www.epa.gov/safewater/lead. Drinking water levels The U.S. Environmental Protection Agency sets MCL’s at very stringent levels. In developing these standards, USEPA assumes that the average adult drinks two liters of water each day throughout a 70-year lifespan. USEPA generally sets MCL’s at levels that will result in no adverse health affects for some contaminants or a one-in-one million chance of having the described health effect for oth- er contaminants.

Two samples were required and one was analyzed. The result of the one sample analyzed was satisfactory. We have since been collecting the proper number of samples. ADDITIONAL INFORMATION ABOUT YOUR WATER The PSA is continually working to maintain the quality of your water and to improve your water distribution system. Over the past few years many old and undersized water lines have been replaced; most of the PSA’s residential water meters have been replaced, and several pressure reducing control valves have also been replaced. In the coming years these improvements will continue Other major improvements have been an inspection and maintenance contract to a company for the PSA’s water tanks. This company on a scheduled basis washes out, disinfects, paints and repairs both the interior and exterior of the water tanks. Another company has been contracted to inspect, pressure and flow test, and maintain the PSA’s fire hydrants. They have also painted and color coded the PSA fire hydrants based on pressure and flows.
