The test hole was excavated to a depth of <br /> .ppr:)ximately 41 inches and 4-inch diameter perforated P` 3 pipe was inserted <br /> into the test hole. The test hole was then filled to the surface with relati- <br /> vely clean water and left to soak overnight. <br /> On June 30, 1987, a representative of our firm returned to the site to per- <br /> form the percolation test. The test was performed according to San Joaquin <br /> County guidelines and the last 30 minutes was observed by a county health <br /> officer. The percolation test was measured to have a percolation rate of <br /> approximately 1 minute per inch. A copy of the county approved test sheet is <br /> attached to this letter. <br /> If you have any questions or need additional informations, please contact <br /> US. <br /> Respectfully submitted, <br /> J.
