KLEINFELDER <br /> CONCLUSIONS <br /> Based on the above evaluation, we conclude that wastewater produced by the proposed leach <br /> fields should not have a nitrate as nitrogen (N) concentration at the groundwater level greater <br /> than 10 mg/l. The results of our percolation tests indicate that conventional septic tankileach <br /> trench sewage disposal systems with seepage pits should adequately serve the proposed shop <br /> building and replacement area. The seepage pits should extend as deep as possible into the <br /> sandy soils underlying the site that were encountered at a depth of about 23.5 to 24 feet below <br /> site grade. <br /> LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> proposed development and on the site conditions. It was assumed that the percolation test results <br /> are representative of the subsurface conditions in the general area. <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.
