la � <br /> File No. 20-3551-01 II n KLEIN FELDER <br /> January 27, 1992 S <br /> bbb <br /> M C-5: <br /> "other -.p�reformation as required by the San Joaquin Local Health <br /> District1to determine the cumulative effect of the existing and the <br /> propose developmentilon groundwater contamination;" <br /> li II <br /> Our scope of services did not include a detailed evaluation <br /> of the potential for the septic systems to affect the <br /> quality of groundwater. However, the project involves only <br /> r a maximum of sixteen systems on an approximate 150-acre <br /> property. Therefore, with groundwater at least 140 to 145 <br /> feet deep, the hikelihood of a significant change in the <br /> nitrate level of'ithe groundwater beneath the site is very <br /> remote. If additional more concentrated development is <br /> planned in the area, we suggest that consideration be given <br /> to completing anitrate loading study. <br /> This completes our scope of work at this time. Based on the above <br /> information, it is or opinion that the subdivision is suitable for <br /> septic system use. The septic systems should be located and future <br /> wells should be constructed following County requirements <br /> Continuous monitoring of the septic systems should be maintains <br /> throughout the duration of their use. Once this report is reviewed <br /> by Environmental Health Services, we would be pleased to furnish a <br /> proposal for providing whatever additional information they may <br /> require for their evaluation. <br /> We trust this report presents the information required at this <br /> time. If you have!; any questions regarding this report and the <br /> attached information, please contact us. <br /> `i <br /> Respectfully submitted, <br /> KLEINFELDER, INC. <br /> i Steven R.
