n <br /> CONCLUSIONS AND RECOMMENDATIONS <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 6.6 minutes per inch <br /> was observed. <br /> The depth of ground water based on recent aquifer levels is relatively deep and <br /> approximately 115 to 125 feet below the ground surface. The ground-water flow <br /> direction is to the north at a rate of 7.4 to 9.5 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 field systems on the Site is not expected to <br /> cause a buildup of nitrate in the aquifer above 4,05 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 /> LOG El003 Page 14 <br />
