Harney Lane <br /> Lodi, CA 95240 <br /> RE: DBCP in your Water Well for PA-03-638 (UP) <br /> As part of the landuse application process, water test results were submitted by Neil Anderson& <br /> Associates, Inc, in which a sample taken February 10, 2005, was tested for the chemical <br /> Dibromochloropropane (DBCP) and showed results of 0.984ug/L (parts per billion) in your <br /> domestic well at 16100 E. Harney Lane, Lodi, CA. <br /> The State Department of Health Services adopted a standard of 0.2 parts per billion (ppb) for <br /> DBCP in public drinking water systems in 1989; however,private well owners are not legally <br /> required to meet this standard. As a precaution for yourself and family, we would suggest that <br /> you have your domestic well tested annually to verify if the above-described chemical rises <br /> above state drinking standards. <br /> If your private and/or agricultural well analysis for Dibromochloropropane exceeded the State <br /> standard of 0.2 ppb, 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 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 DBCP if it is 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 ently filters, which <br /> treat water for the entire house, are recommended because they remove all potential sources_ <br /> of exposure. The "ffanular activated carbon" filter is the recommended water treatment <br /> device in this case. It operates by passing the well water through a charcoal bed, thereby <br /> absorbing the DBCP contaminant. Water treatment equipment suppliers and installers are <br /> listed in your phone directory yellow pages under"Water Filtration& Purification <br /> Equipment." <br />
