West Ripon Rd., Ripon <br /> The Environmental Health Department has received water test results taken by Chesney <br /> Consulting. The sample taken on May 11th, 2017, was tested for nitrates and showed results of <br /> 84 mg/L (milligrams per litre) Nitrate in your domestic well at 13391 W. West Ripon Rd., Ripon. <br /> The State Department of Health Services adopted a standard of 45 mg/L for Nitrate in public <br /> drinking water systems; however, private well owners are not legally required to meet this <br /> standard. As a precaution for yourself, members and guests, the Environmental Health <br /> Department would suggest that you have your domestic well tested annually to verify if the <br /> above-described chemical continues to be above state drinking standards. <br /> If your private well analysis for nitrate exceeds the State standard of 45 mg/L 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. Infants below the age of six months who drink water <br /> containing nitrate in excess of the MCL may quickly become seriously ill and, if untreated, <br /> may die because high nitrate levels can interfere with the capacity of the infant's blood to <br /> carry oxygen. Symptoms include shortness of breath and blueness of the skin. High <br /> nitrate levels may also affect the oxygen-carrying ability of the blood of pregnant women. <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 in your private water supply. Most treatment units <br /> sold for home installation only treat water at the point of use, such as the kitchen faucet, <br /> and do not prevent exposure through skin contact, bathing or inhalation. As a result, point <br /> of entry filters, which treat water for the entire house, are recommended because they <br /> remove all 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 /> 1868 E.
