VII. GROUNDWATER <br /> A Groundwater test was performed on the property well (A.P.N. 007-370-04). <br /> Extensive research through County records by my staff and Environmental Health's <br /> staff could not locate the well permit. I have to assume it was misfiled. The well <br /> was tested for nitrates and DBCP. The samples were taken by Mike Toy of <br /> Dillon & Murphy and driven directly to Precision Enviro-Tech. Water was taken from a <br /> spigot at the house. The results can be found in the appendix. The results did not <br /> yield any reason of concern regarding groundwater in the area. <br /> VIII. CONCLUSION <br /> Based on the results of the percolation test and the soil profile, it is <br /> Dillon & Murphy's opinion that the existing homesite resulting from the proposed <br /> parcel split of the subject property are suited for an engineered on-site sewage <br /> disposal system. If an appropriate strata is found by additional testing, then the <br /> system could be simply leach lines and seepage pits. The soil type and lithology is <br /> homogenous in the immediate area and leach lines with pits have worked <br /> sufficiently. The proposed system however, should be properly designed and <br /> installed according to the current San Joaquin County criteria. <br /> Based on the depth to ground water in the area, and the size of the proposed <br /> parcel, it is our opinion that the installation of any new proposed septic system, if <br /> properly installed, should not adversely affect the quality of ground water in the <br /> area. <br /> IX. LIMITATIONS <br /> The conclusions of this report are based on the information provided <br /> regarding the proposed development, the use of the subject property, and the site <br /> conditions as they existed at the time we excavated our test holes and performed <br /> the percolation tests. It was assumed that the test hole and percolation tests <br /> results are representative of the subsurface conditions in the general area. <br /> Our services were performed, our findings obtained, and our conclusions <br /> proposed in accordance with generally accepted engineering principles and <br /> practices.
