Kennedy/Jenks Consultants <br /> Section 5: Proposed Activities - Groundwater Monitoring <br /> Network <br /> 5.1 Location and Rationale <br /> Three additional groundwater monitoring wells are proposed to satisfy the intent of the Title 27 <br /> DMP. The locations of these wells are presented on Figure 9. Installation details applicable to <br /> installation and drilling of all wells, including provisions for evaluating potential zones of higher <br /> conductivity, can be found in Section 5.2. <br /> Well MW-20R is proposed to be installed in the immediate vicinity of Well MW-20. This well is <br /> anticipated to be installed in the intermediate zone and groundwater is anticipated to be <br /> encountered at approximately 105 feet bgs. Well MW-20R will serve as a downgradient/ <br /> compliance well suitable for detecting a release from the Title 27 ponds. It should be noted that <br /> the installation of Well MW-20R is currently proposed to the RWQCB (Musco 2010). <br /> Well MW-21R is proposed to be installed in the immediate vicinity of Well MW-21. This well is <br /> anticipated to be installed in the intermediate zone and groundwater is anticipated to be <br /> encountered at approximately 105 feet bgs.Well MW-21R will serve as a <br /> downgradient/compliance well suitable for detecting a release from the Title 27 ponds. <br /> Well MW-19R is proposed to be installed approximately 380 feet southwest of Title 27 ponds. <br /> This well is anticipated to be installed in the intermediate zone and groundwater is anticipated to <br /> be encountered at approximately 99 feet bgs.Well MW-19R will serve as the upgradient/ <br /> background monitoring well for the Title 27 DMP. <br /> 5.2 Field Activities <br /> The following field activities will be conducted: drilling the soil borings and installing monitoring <br /> wells, developing the wells, and collecting groundwater samples from monitoring wells for <br /> laboratory analysis. <br /> 5.2.1 Pre-Field Activities <br /> The following pre-field activities will be conducted prior to initiating fieldwork at the Site: <br /> • Update the site-specific Health and Safety Plan. <br /> • Obtain well installation permits from the San Joaquin County Environmental Health <br /> Department. <br /> • Select and mark the specific locations for the new monitoring wells. <br /> • Survey the proposed boring locations for potential location conflicts with subsurface <br /> utilities by performing a utility clearance check prior to drilling. The survey will be <br /> performed by contacting Underground Service Alert (USA) for utility clearance at least <br /> two working days before the scheduled fieldwork commences. <br /> Page 12 Work Plan for Improved Detection Monitoring Program <br /> Musco Family Olive Company, Tracy, California <br /> 9. gmupWnnyoWX20104 oom�wlveN9 modsmm 27_dmpWf dwumomlreport text-09-26.doc <br />
