Jahant Road <br /> Acampo, California 95220 <br /> RE: Nitrates in your Water Well for Minor Subdivision PA-07-00523 (MS) <br /> As part of the Minor Subdivision process, water test results were submitted by Neil O. Anderson <br /> and Associates in which samples taken July 29, 2005 was tested for nitrates and showed results <br /> of 145 parts per million (145 ppm) in your domestic well at 1525 E. Jahant Road, Acampo. <br /> The State Department of Health Services adopted a standard of 45 parts per million(ppm) for <br /> nitrates in public drinking water systems; however, private well owners are not legally required <br /> to meet this standard. As a precaution for yourself, members and guests, the Environmental <br /> Health Department would suggest that you have your domestic well tested annually to verify if <br /> the above-described chemical continues to be above state drinking standards. <br /> If your private well analysis for nitrate exceeds the State standard of 45 ppm again, the following <br /> alternatives are being provided for your guidance: <br /> 1. As a temporary measure, it is recommended that bottled drinking water be used if this well is <br /> supplying drinking water. <br /> 2. In cases where exposure may continue indefinitely, such as with contaminated private wells, <br /> installation of a water treatment device, such as a filter, may be advisable. However, using <br /> bottled water or installing a water treatment device at the kitchen water tap,will not stop <br /> exposure to nitrates in your private water supply. Most treatment units sold for home <br /> installation only treat water at the point of use, such as the kitchen faucet, and do not prevent <br /> exposure through skin contact, bathing or inhalation. As a result, point of enta filters, which <br /> treat water for the entire house, are recommended because they remove all potential sources <br /> of exposure. The "Reverse Osmosis Purification Filter" is the recommended water treatment <br /> device in this case. It operates by passing the well water through a series of filters and <br /> reverse osmosis membranes thereby removing the nitrate contaminant. Water treatment <br /> equipment suppliers and installers are listed in your phone directory yellow pages under <br /> "Water Filtration &Purification Equipment." <br />
