CONCLUSIONS AND RECOMMEN ATIONS <br /> In summary, the soil conditions examined near the loca ion of the septic system drain <br /> field appear to be suitable. A satisfactory soil percolatiol rate of 11.4 minutes per inch <br /> was observed. <br /> The depth of ground water based on recent aquifer levels is relatively deep and <br /> approximately 85 to 90 feet below the ground surface. 1he ground-water flow direction <br /> is to the north at a rate of four feet per mile or less in the vicinity of the Site. <br /> Because the wells on the Site are not operational at this time, no water sample was <br /> collected for this study. <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 3.42 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 /> LOGE 1123 Page 14 <br />
