INTRODUCTION <br /> Our office was contracted by Mr. Lowell Grissom of the Weston Ranch Congregation of <br /> Jehovah's Witnesses, to conduct a soil suitability/nitrate loading study for the proposed church <br /> facility located at 7960 S. Ponderosa Street& French Camp Road, French Camp, California <br /> (Plate 1). <br /> The soil suitability/nitrate loading study was conducted to determine if the soils are <br /> suitable for the use of a septic system and to estimate whether the proposed project will impact <br /> ground-water quality. The study was performed according to the requirements of Section 9- <br /> 1105.2(d) of the San Joaquin County Development. Major elements of the field work included <br /> one(1) soil boring and one(1) in-situ percolation test,required by San Joaquin County Public <br /> Health Services Environmental Health Division(SJC PHS-EHD) for project approval. <br /> In addition to conducting the field work, a review of published soil information, geologic <br /> maps, and available ground water information was reviewed to determine the suitability of soils. <br /> Due to San Joaquin County Public Health Services, SJC PHS-EHD's concern of nitrate <br /> contamination of shallow ground water in the area, a nitrate loading balance was an additional <br /> requirement for project approval. The nitrate loading study was conducted to estimate the <br /> potential impact of leaching nitrates from the septic system into ground water. This report <br /> presents the results of our study. <br />
