Weber: 1*f�:r.;..'ATi; .;c' 1.;;f:co--I tnlFO MATln*.A'l f OS. :.,. <br /> A water sample was taken on November 5, 1990 from the <br /> outside faucet at the above referenced location, examined by <br /> the State Laboratory of Hygiene and found to be <br /> bacteriologically safe due to the fact that no bacteria of , <br /> the coliform group were found in the sample portions <br /> examined. . <br /> The water sample was also examined for nitrate concentration <br /> and results indicate a level of 8.5 milligrams of nitrate as <br /> nitrogen per liter of water. This level is below the United <br /> States Public Health Service standard of 10 milligrams per <br /> liter. Therefore, the nitrate level should be safe for <br /> consumption by all family members, including infants under <br /> six months of age. <br /> The private water supply consists of a joint well which is <br /> located at 3796 Park Knoll Drive. The observable portions of <br /> the well appear to comply with the minimum criteria of <br /> Wisconsin Administrative Code ch NR 112. <br /> Our file indicates that the private sewage system serving <br /> this premises was installed by Walter Hensler , MP #4034, in <br /> December of 1976. Designed to serve a 4 bedroom house, the <br /> system consists of a 1 ,200 gallon prefabricated concrete <br /> septic tank and a 1 ,008 square foot drainfield . There were <br /> no external physical signs of failure that were apparent at <br /> the time of my inspection. Current ILHR codes would require <br /> a minimum drainfield of 1 ,260 square feet. Two inches of <br /> ponding was observed in the drainfield vent pipe. <br />
