CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions in the percolation test location appear to be suitable for <br /> use with an on-site septic system. A satisfactory soil percolation rate of 6.25 min/in was <br /> observed in the test location. <br /> The depth of ground water based on recent aquifer levels is estimated to range between <br /> 80 to 85 feet below ground surface. The ground-water flow is to the north or northeast <br /> at a rate of 12 to 33 feet per mile. <br /> A water sample was collected from the domestic water well. Nitrate was detected in the <br /> sample at a concentration of 3.3 mg/L-N, well below the MCL of 10 mg/L-N. DBCP was <br /> detected in the sample at a concentration of 0.02 µg/L, below the MCL. The US EPA <br /> set the MCL for DBCP at 0.2 parts per billion (ppb, equivalent to µg/L) because it <br /> believes that, given present technology and resources, this is the lowest level to which <br /> water systems can reasonably be required to remove this contaminant should it occur in <br /> drinking water. The Maximum Contaminant Level Goal (MCLG) for DBCP is zero. <br /> We believe the Site suitable for the use of a standard septic system utilizing leach lines <br /> and seepage pits. No new construction is anticipated. <br /> • <br /> • <br /> LOGE 1721 Page 8 <br />
