<br /> inches of fine gravel at the bottom. of the borehole. The hole is then pre-soaked with water at
<br /> least 24 hours prior to performing the test. The test is performed by adding up to a maximwn of
<br /> 24 inches of water above the gravel in the Bole. From a fixed reference point, the drop in water
<br /> level is measured in approximately 30-minute intervals for four hours, refilling as necessary to
<br /> maintain the prescribed amount of water over the gravel. Under the observation of a sanitarian
<br /> from the San Joaquin County Public Health Services, Environmental Health Division
<br /> (SJCPHS/EHD), the last 30-minute reading of the four hour period is recorded and used to
<br /> calculate the percolation rate in minutes per inch. The estimated percolation rates are
<br /> summarized below. A, copy of our field percolation test results signed by a representative from
<br /> SJCPHS/EHD is attached. The August 28 inspection was performed by Steven Shih and the
<br /> September 9 inspection by Johnny Yoakum.

<br /> It was assumed that the percolation test results arc representative of the subsurface conditions in
<br /> the general area of the tests. Based on these results, it is our opinion that a conventional system
<br /> with seepage pits at the end of the leach line can be used on this property. Due to the variability
<br /> of the soils encountered at this site,we recommend that seepage pits extend 25 feet below grade.
<br /> This completes the scope of work requested. Our work was performed in general accordance
<br /> with the standard of care that exists in San Joaquin County. No other guarantee or warranty,
<br /> expressed or implied,is made.
