CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions near the percolation tests appear to be suitable for use <br /> with an on-site septic system. Satisfactory soil percolation rates of 8.1 min/in (Parcel <br /> 1), 20.8 min/in (Parcel 2), 3.7 min/in (Parcel 3), and 3.3 min/in (Parcel 4) were observed �J <br /> in the test locations. No new construction is proposed at this time. With a satisfactory <br /> test, the area 100 feet in radius from the test location could be used to construct a <br /> septic system drain field. <br /> The depth of ground water based on recent aquifer levels is relatively deep, <br /> approximately 140 to 275 feet, depending on the season and the location on the Site. <br /> The ground-water flow direction is to the west or southwest at a rate of approximately <br /> 35 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 6.1 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 /> VVe believe the Site suitable for development with the use of standard septic systems ' <br /> utilizing leach lines and seepage pits. <br /> LOGE 1126 Page 10 <br />
