CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions near the percolation tests appear to be suitable for use <br /> with on-site septic systems. Satisfactory soil percolation rates of 19.2 min/in (Parcel 1) <br /> and 31.2 min/in (Parcel 2) were observed in the test locations. No new construction is <br /> proposed at this time. With a satisfactory test, the area 100 feet in radius from the test <br /> location could be used to construct a septic system drain field. <br /> The depth of ground water based on recent aquifer levels is 22 to 36 feet, depending on <br /> the season. The ground-water flow direction is to the southwest at a rate of <br /> approximately five to seven feet per mile in the vicinity of the Site. <br /> A water sample was collected from the irrigation water well on the Site. Nitrate was <br /> detected in the water sample at a concentration of 2.2 mg/L, well below the MCL of 45 <br /> mg/L. DBCP was not detected in the water sample. <br /> Based on the results of this study, we believe the Site has satisfied the requirements of <br /> the Environmental Health Department for the use of standard septic systems utilizing <br /> leach lines and sumps. <br /> LOGE 1401 Page 8 <br />
