Soil Chemical Analysis: <br /> Soil types at Manuel Da Silva dairy operations; referenced from the Soil Survey of San Joaquin <br /> County, soil panel#27,Escalon Quadrangle: <br /> Soil# 193: <br /> Madera Sandy Loam,0-2%slope. <br /> Moderately drained. Moderately deep to hardpan. <br /> Very slow permeability. <br /> Hardpan at depths of 20-40 inches. <br /> Rainfall perched above the claypan and hardpan. <br /> The rate of water intake in irrigated areas is 1.5 inches per hour. <br /> Soil# 195: <br /> Madera-Alamo complex, leveled,0-1%slope. <br /> 80%Madera sandy loam and 20%an Alamo soil, overburden of sandy loam. <br /> Having been leveled and ripped,there are remnants of claypan and hardpan. <br /> Permeability is very slow. <br /> Water can be perched above the clay pan after a rainfall and irrigation. <br /> The rate of water intake in irrigated areas is 1.5 inches per hour. <br /> Soil#236: <br /> San Joaquin Sandy Loam,0-2%slope. <br /> Moderately well drained. <br /> Moderately deep to a hardpan. <br /> Permeability is very slow. <br /> Water capacity is very low. <br /> The rate of water intake in irrigated areas is 1.5 inches per hour. <br /> Approximate coverage of farmed properties, reference aerial soils map(appendix,fig. 1): <br /> Soil type: # 193 # 195 4236 <br /> Owner property: 95% 4.5% 0.5% <br /> Rented property 70% 0.0% 30% <br /> Soil Boring Installation: <br /> On January 15, 1999,two soil borings were installed at the Manuel Da Silva dairy site(reference site <br /> map). All soil boring drilling was performed by Frontier Drilling of Turlock,California, a contractor <br /> licensed in the State of California to conduct such activities. All drilling was conducted under the direct <br /> supervision of AGS personnel who logged and collected the samples for analysis. <br /> The borings were advanced using six inch outside diameter, continuous flight, solid-stem augers. <br /> During drilling,the project geologist logged all drive samples and cuttings continuously using the Unified <br /> Soil Classification system. Soil boring logs are contained within Appendix B. <br /> Each soil boring was advanced to a depth of forty feet. Ground water was not encountered in any of the <br /> soil borings. After completion, all soil borings were back filled with a neat cement slurry to existing grade <br /> and covered with native soil. <br /> 4 <br />
