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 <br /> 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 <br /> is 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 <br /> prevent exposure through skin contact, bathing or inhalation. As a result, point of entry <br /> filters, which treat water for the entire house, are recommended because they remove all <br /> potential sources of exposure. The "Reverse Osmosis Purification Filter" is the <br /> recommended water treatment device in this case. It operates by passing the well water <br /> through a series of filters and reverse osmosis membranes thereby removing the nitrate <br /> contaminant. Water treatment equipment suppliers and installers are listed in your phone <br /> directory yellow pages under "Water Filtration & Purification Equipment." <br /> Nitrate Well 11/1/00 <br />
