measurements were taken every half-hour during this four-hour period. Ted Tasiopoulos or Michael Escotto, Senior Registered Environmental Health Specialists at the San Joaquin County Environmental Health Department, observed the last half-hour of each test. An electronic well sounder with a depth accuracy of 1/100"' 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 holes were refilled with water to a level of six inches 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. Tasiopoulos or Mr. Escotto and indicate a 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. For each proposed parcel on the Site to utilize a standard septic system, one percolation test must demonstrate a satisfactory percolation rate within the proposed septic system disposal field. Details and results of the percolation tests are summarized in the following table: Table 2.
