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 forms are included in Appendix 3 of this report. The <br /> forms were signed by Mr. Escotto and indicate percolation rates for the holes based on <br /> 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 proposed parcels of the Site. Details and <br /> results of the percolation tests are summarized in the following table. <br /> Table 2.
