CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions examined near the septic system drain field for each <br /> duplex appear to be suitable. Satisfactory soil percolation rates were observed at both <br /> test locations. <br /> The depth of ground water based on recent aquifer levels is approximately 78 to 85 feet <br /> below the ground surface, depending on the season and location on the Site. The 2 J <br /> ground-water flow direction is to the east-southeast at a rate of approximately four to <br /> seven feet per mile in the vicinity of the Site. <br /> The on-site domestic water well was not tested for nitrate and DBCP; power was cut to <br /> the Site during the fire response, and as a result the well is currently inoperable. <br /> Based on the current project, the use of on-site septic tanks and drain field systems on <br /> the Site is not expected to cause a buildup of nitrate in the aquifer above 6.01 mg/L-N. j <br /> This level falls below the US EPA drinking water recommendation of 10 mg/L-N. <br /> We believe the Site suitable for development with the use of standard septic systems. <br /> �" LOGE 1515 Page 13 <br />
