observed by Ted Tasiopoulos, Senior Registered Environmental Health Specialist at the <br /> San Joaquin County Environmental Health Department. <br /> An electronic well sounder with a depth accuracy of 1/100th foot was utilized for the <br /> water level measurements. The water level was measured against a fixed reference <br /> point on the well casing. Measurements were recorded on the data sheet in decimal <br /> feet. When necessary after measuring the water level, the hole was refilled with water <br /> to a level of six inches or more above the bottom of the hole. <br /> Percolation Test Results <br /> The completed percolation test form is included in Appendix 3 of this report. The form <br /> was signed by Mr. Tasiopoulos and indicates the percolation rates for the holes based <br /> on the final water drop observed. <br /> Per San Joaquin County Environmental Health Department's definition, a shallow <br /> percolation test hole has a depth between 36 and 42 inches; a satisfactory percolation <br /> rate for a shallow test is less than or equal to 60 minutes per inch (min/in) drop. A deep <br /> percolation test hole has a depth greater than 3.5 up to 25 feet; a satisfactory <br /> percolation rate for a deep test is 30 min/in or less. For the Site to utilize a standard <br /> septic system, one percolation test (either a shallow or deep test) must demonstrate a <br /> satisfactory percolation rate within the proposed septic system disposal field. <br /> Only shallow tests were performed for the Site. Details and results of the percolation <br /> L tests are summarized in the following table. <br /> Table 2.

A satisfactory percolation rate for a "shallow' test is less than or equal to 60 minutes per inch. A satisfactory <br /> percolation rate for a "deep"test is less than or equal to 30 minutes per inch. <br /> LOGE 1304 Page 7 <br />
