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 holes were 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. Wong or Ms. Beniamine and indicate the percolation rate for <br /> each hole based 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 greater than 1 min/in but less than or equal to 60 minutes per <br /> inch (min/in) drop. For the Site to utilize a standard septic system, one percolation test <br /> must demonstrate a satisfactory percolation rate within the proposed septic system <br /> disposal field. <br /> Details and results of the percolation tests are summarized in the following table. <br /> LOGE 1811 Page 7 <br />
