01 July 2016 AGE Project No. 15-3403 Page 9 of 12 8.1 . SITE MAP A site map showing the approximate location of percolation test hole is illustrated on Figure 2. A precise description of the location and construction of the percolation test hole is included in Appendix D (EHD form 42-03). The soil suitability study was conducted within 10-feet of the location of a proposed replacement septic system leach field. 8.2. NUMBER OF PERCOLATION TESTS PERFORMED One, shallow, percolation test was conducted on site. The normal percolation of the test hole required the performance of a 24-hour percolation test, with a two hour observation time period. 8.3. CONSTRUCTION OF PERCOLATION TEST HOLE On 29 June 2016, one soil boring was advanced for a shallow percolation test. The boring was advanced using a four-inch hand auger to a depth of 48-inches bsg. The boring was located more than 100 feet from the current well location and within 50 feet of a possible septic system replacement leach-line location. Following bore hole advancement, the sides of the boring were scraped and loose material was removed from the bore hole. Once the bore hole was cleared of loose material, a test pipe was installed within the boring and 4 inches of sand and/or gravel were added to the bore hole. The bore hole was then filled with water to a depth of 12 inches above the gravel at the time of 0830. Test hole was covered for 24 hours to allow for complete saturation of the bore hole. 8.4. DESCRIPTION OF THE PERCOLATION TEST HOLE - POST SOAK On 30 June 2016, the boring was found to be completely dry, but intact and in good condition. 8.5. PERCOLATION TEST CONFORMED TO SJC POLICY EHD 02-02 The work was performed under SJCCDD Title Requirements Section 9-1105.2 (d) and as required by EHD. On 30 June 2016, test hole one was inspected prior to initiation of the percolation test. The percolation test was performed by recording the amount of water remaining in the bore hole at 30-minute intervals. The initial 6-inches of water seeped from test hole in Advanced GeoEnvironmental,Inc.
