/ CONCLUSIONS AND RECOMMENDATIONS <br /> .v <br /> In summary, the soil conditions examined near the location of the septic system drain <br /> field appear to be suitable. A satisfactory soil percolation rate of 7.3 minutes per inch <br /> was observed. The exact location of the drain field has not been determined. However, <br /> the percolation tests represent an area of approximately 100 feet in radius. <br /> The depth of ground water based on recent aquifer levels is relatively deep and <br /> approximately 122 to 132 feet below the ground surface. The ground-water flow <br /> direction is to the north at a rate of 5.6 to 6.5 feet per mile. <br /> The on-site domestic water well was tested for nitrate and DBCP. Results of the testing <br /> will be forwarded once they are received from the laboratory. <br /> The use of on-site septic tanks and drain ief I systems on he Site is not expected to <br /> cause a buildup of nitrate in the aquifer above .89 mg/L-N, hich is well below the US <br /> EPA drinking water recommendation of 10 mg -N. In f t, the actual impact to the <br /> aquifer will be much less since the equation is copse a and overestimates impacts. <br /> We believe the Site suitable for development with the use of standard septic systems. <br /> We do not anticipate that the ground water quality will be negatively impacted, primarily <br /> /-� due to the low calculated nitrate level. No nitrate mitigation is recommended. <br /> LOGE0915 Page 14 <br />
