CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions examined near the location of the septic system drain <br /> field appear to be suitable. Satisfactory soil percolation rates of 25 minutes per inch for <br /> the shallow zone and 3.6 deep minutes per inch for the deep zone were observed near <br /> the drain field area. <br /> The depth of ground water based on recent aquifer levels is relatively deep and <br /> approximately 70 to 80 feet below the ground surface. The ground water flow direction <br /> is to the northeast at a rate of 4.5 to 5.7 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 field systems on the Site is not expected to <br /> i cause a buildup of nitrate in the aquifer above 6.16 mg/L-N, which is well below the US <br /> EPA drinking water recommendation of 10 mg/L-N. In fact, the actual impact to the <br /> aquifer will be much less since the equation is conservative 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 /> LOGE0914 Page 13 <br />
