JF <br /> KLEINFELDER <br /> 2 <br /> 6 RECOMMENDATIONS <br /> 6.1 RECOMMENDATIONS <br /> Based on Kleinfelder's findings and the desires of CDD and PHS/EHD the following <br /> recommendations were developed: <br /> 1. Continue quarterly groundwater soundings of the two monitoring wells MW-1 and MW-2 to <br /> monitor potential perched water and/or seepage between the Delta Mendota Canal and a <br /> proposed settling basin near the proposed`gravel pit area (Phase D. If groundwater Is <br /> encountered CDD and Kleinfelder should be contacted and groundwater samples collected for <br /> potential analyses. <br /> F <br /> 2. The well head for two deep wells(DW-1 and DW-3) and the domestic well (DOM-1) should be <br /> inspected and fitted with a sounding port for future groundwater sampling events. Additionally, <br /> if possible, each of these wells including deep well DW-2B should be shut down for 24 to 48 <br /> hours prior to obtaining water levels so reliable groundwater elevation data can be obtained (Le. <br /> pumping wells do not reflect static groundwater conditions). <br /> 3. Each of the six wells (three deep wells, one domestic well and the two monitoring wells) should <br /> be surveyed (after sounding ports are installed), so future groundwater elevations, groundwater <br /> flow directions and gradients can be calculated. <br /> 4. Continue annual groundwater sampling of the three deep wells and the domestic well at the <br /> request of the PHS/EHD. Future groundwater sampling results should be compared to the <br /> initial results (those contained within this report) as background levels since the gravel pits were <br /> proposed at the time of sampling of the wells. <br /> 5. Kleinfelder recommends that a copy of this report should be submitted to San Joaquin <br /> County Public Health Services Department, Environmental Health Division (PHS/EHD) and <br /> the San Joaquin County Community Development Department, Development Services <br /> Division (CDD) for their review and comment. <br /> This report, and the conclusions and recommendations presented in this Executive Summary, are <br /> ° subject to the "Limitations" presented in Chapter 7 of this report.
