CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, the soil conditions near the percolation test appear to be suitable for use <br /> with an on-site septic system. A satisfactory soil percolation rate of less than 1.3 <br /> min/in was observed in the test location. No new construction is proposed at this time. <br /> With a satisfactory test, the area 100 feet in radius from the test location could be used <br /> to construct a septic system drain field. <br /> The depth of ground water based on recent aquifer levels is approximately 38 to 41 feet, <br /> depending on the season. The ground-water flow direction is to the north at a rate of <br /> approximately six feet per mile in the vicinity of the Site. <br /> A water sample was collected from the domestic water well on the Site. Nitrate was <br /> detected at a concentration of 137 mg/L-NO3 in the water sample, this result exceeds <br /> the US EPA's Maximum Contaminant Level (MCL) of 45 mg/L. DBCP was not detected <br /> in the sample. It is suggested that Mr. Tavares discuss methods of reducing nitrate <br /> levels in the drinking water with the Environmental Health Department and/or a well <br /> contractor. For health reasons, Live Oak recommends that the well water not be <br /> consumed until nitrate levels can be reduced to below the MCL. Utilizing bottled water <br /> for drinking may be a good alternative to consider. <br /> We believe the Site suitable for the use of standard septic systems utilizing leach lines <br /> and sumps. <br /> LOGE 1328 Page 9 <br />
