01 October 2019 <br />AGE Project No. 19-4850 <br />Page 6 of 14 <br />(Nutrien AG Solutions-CPS) is located at 1905 North Broadway Avenue, approximately <br />2,200 feet north and down-gradient of the subject property. Based on the status of the <br />LUSTs and their distance and direction from the subject property, the LUSTs should not <br />impact the subject property. The review did not reveal any other sites of environmental <br />concern within a half-mile radius of the site. <br /> <br /> <br />4.3. ON-SITE EXISTING WELL DESCRIPTION <br /> <br />There are no water wells on the property. The existing potable water service is provided <br />by the California Water Service Company. <br /> <br /> <br />4.4. CONSTITUENTS BEING TESTED FOR IN THE WATER SAMPLE <br /> <br />The potable water supply to the subject property was not tested because water is provided <br />to the site by the California Water Service Company. <br /> <br /> <br />5.0. SOIL PROFILE <br /> <br />An OWTS Permit was issued for the property by the EHD on 06 September 2019 to <br />perform a percolation test (Appendix C). On 17 September 2019, a 4-inch diameter hand <br />auger was utilized to advance a percolation test hole to 42 inches bsg, approximately 35 <br />to 40 feet south of the existing septic system disposal field area. <br /> <br />A plan of the specific site features including the percolation test hole location <br />(i.e., structures, drives, wells, septic systems, large trees, pastures, pools, natural <br />drainage courses, ponds, waterways, etc.) is illustrated in Figure 2. <br /> <br /> <br />5.1. SOIL PROFILE PIT INCLUDING DEPTH AND DIMENSIONS <br /> <br />The percolation test hole was located approximately 35 to 40 feet from the disposal field <br />area of the existing septic system. The percolation test hole was advanced to a depth of <br />42 inches bsg using a four-inch diameter hand auger (Figure 2). <br /> <br /> <br />5.2. SOIL LITHOLOGY AS RELATED TO FUTURE ONSITE SEPTIC USES <br /> <br />The soil was visually described in accordance with the Unified Soil Classification System <br />by a representative of AGE under the supervision of a California Professional Geologist. <br />The soil collected from the percolation test hole boring consisted of dry, clayey fine- <br />grained sand/sandy clay from surface grade to total depth. The soil type is considered <br />semi-permeable and sufficient for liquid waste disposal and treatment. <br />
