It was <br /> subsequently repaired, and a water sample was collected. The following pages present the <br /> results of the water sampling. <br /> Water Sample Location <br /> One water sample was collected from the agricultural well sprinkler system outlet on November <br /> 12, 2007 by Jessen Welch of NOA. <br /> Water Sample Constituents <br /> The water sample was analyzed for nitrate and DBCP. Neither constituent was detected. The <br /> analytical reports prepared by FGL Environmental are attached to this letter. <br /> The presence of nitrates is not uncommon in shallow ground water aquifers in San Joaquin <br /> County and other parts of the Central Valley. Nitrate in ground water occurs as a result of the <br /> application of fertilizers, livestock waste, and untreated septic tank waste. Nitrate is mobile and <br /> often accumulates in the shallow ground water zones. <br /> In the early 1900s, natural levels of nitrate in ground water were measured in forty-three (43) <br /> wells throughout the Sacramento Valley by Bryan (1923). It was thought that ground water at <br /> that time was close to "natural" conditions. Based on the work by Bryan, it is estimated that <br /> under"natural"conditions, ground water concentration containing nitrate is no more then about <br /> ANGELS CAMP • LODI MODESTO RENO • SACRAMENTO - WALNUT CREEK <br /> L 0 D 1 902 Industrial Way Lodi,CA 95240 209.367.3701 • FAX 209-369.4228 • www.noanderson.com <br />
