Q. <br /> 304 East Weber Avenue, Third Floor • Stockton, CA 95202 ��FpRN <br /> 209/468-3420 <br /> August 10, 1998 <br /> Ike Rai <br /> 9610 Apple Blossom Way <br /> Stockton, CA 95209 <br /> RE: Soil Suitability Study for MS-98-18 at 3400 W. Kingdon Road , Lodi. <br /> A soil suitability study was submitted by Walter E. Curtis, in which a test for Nitrate was tested <br /> for and showed results of 56.4 and 78.8 mg/L (parts per million) in your domestic/agriculture <br /> well(s). <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 and family, we would suggest that you have <br /> your domestic well re-tested to verify the above sample results. <br /> If your private and/or agricultural well analysis for nitrate exceeded the State standard of 45 ppm <br /> again, the following alternatives are being provided for your guidance: <br /> 1. As a temporary measure, it is recommended that bottled drinking water be used if this <br /> well is supplying drinking water. <br /> 2. In cases where exposure may continue indefinitely, such as with contaminated private <br /> wells, installation of a water treatment device, such as a filter, may be advisable. <br /> However, using bottled water or installing a water treatment device at the kitchen water <br /> tap, will not stop exposure to nitrates if it is in your private water supply. Most treatment <br /> units sold for home installation only treat water at the point of use, such as the kitchen <br /> faucet. As a result, point of entry filters, which treat water for the entire house, are <br /> recommended because they remove all potential sources of exposure. The "Reverse <br /> Osmosis Purification Filter' is the recommended water treatment device in this case. It <br /> operates by passing the well water through a series of filters and reverse osmosis <br /> membranes, thereby removing the nitrate contaminant. Water treatment equipment <br /> suppliers and installers are listed in your phone directory yellow pages under"Water <br /> Filtration & Purification Equipment." <br /> A Division of Jan Joaquin Councv i-iealrn Care services <br />
