CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions near the percolation test appear to be suitable for use <br /> with an on-site septic system. A satisfactory soil percolation rate of less than 3.3 <br /> min/in was observed in the test location. No new construction is proposed. With a <br /> satisfactory test, the area 100 feet in radius from the test location could be used toz <br /> construct a septic system drain field. <br /> The depth of ground water based on recent aquifer levels is approximately 40 to 65 feet, <br /> depending on the season. The ground-water flow direction is to the northeast at a rate <br /> of approximately 9 to 14 feet per mile in the vicinity of the Site. <br /> A water sample was collected from the domestic water well on the Site. Nitrate was <br /> detected at a concentration of 20.0 mg/L-NO3 in the water sample, well below the US <br /> EPA's Maximum Contaminant Level (MCL) of 45 mg/L. DBCP was not detected in the <br /> sample. <br /> We believe the Site suitable for development with the use of standard septic systems <br /> utilizing leach lines, leach lines and sumps, or a filter bed. <br /> LOGE 1134 Page 8 <br />
