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

A satisfactory percolation rate for a "deep"test is less than or equal to 30 minutes per inch. LOGE 1213 Page 8
