CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions near each percolation test appear to be suitable for use <br /> with a standard septic system. Satisfactory soil percolation rates ranging from less than <br /> 2.6 to 27.8 minutes per inch were observed for each of the 10 parcels tested. No new <br /> construction is proposed. With a satisfactory test, the area 100 feet in radius from the / <br /> test location could be used to construct a septic system drain field. <br /> The depth of ground water based on recent aquifer levels is approximately 175 to 225 <br /> feet below the ground surface, depending on the season and location on the Site. It <br /> appears that ground water flows down to the west in the vicinity of the Site at a rate of <br /> approximately nine feet per mile. <br /> A sample of water from the southern of the two irrigation wells on the Site was tested for <br /> nitrate and DBCP. Nitrate was detected at 3.9 mg/L-NO3, well below the US EPA's <br /> Maximum Contaminant Level (MCL) of 45 mg/L-NO3 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 and seepage pits. <br /> LOGE 1217 Page 11 <br />
