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 11.9 min/in was <br /> observed in the test location. A new residence may be constructed on the homesite <br /> parcel at some point in the future. With a satisfactory test, the area 100 feet in radius <br /> from the 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 20 to 30 feet. <br /> Groundwater flows down in a southerly direction; a flow rate could not be calculated. <br /> A water sample was collected from the domestic water well on the Site. Nitrate was <br /> detected at a concentration of 53.7 mg/L-NO3 in the water sample, above the US EPA's <br /> Maximum Contaminant Level (MCL) of 45 mg/L. DBCP was not detected in the sample. <br /> Based on the level of nitrate detected, it is recommended that the occupants avoid <br /> drinking or cooking with the well water until the level can be reduced to below the MCL. <br /> The EHD should be contacted for recommendations on a long-term nitrate reduction <br /> strategy. <br /> We believe the Site suitable for development with the use of standard septic systems <br /> utilizing leach lines and sumps or a filter bed. <br /> �" LOGE 1112 Page 8 <br />
