l ! <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 14.7 minutes per inch <br /> was observed. <br /> The de th of round water based on recent aquifer levels is relatively deep and <br /> approximately 120 to 130 feet below the ground surface. The ground-water flow <br /> direction is to the southeast at a rate of five to eight feet per mile in the vicinity of the <br /> J Site. <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. - o� <br /> The <br /> 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 ab 5.3 mg/L-N, which is well below the US <br /> EPA drinking water recommendation 10 1 -N, In fact, the actual impact to the <br /> aquifer will be much less since the equ 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 /> LOGE1005 <br /> Page 14 <br />
