To characterize groundwater quality prior to selecting existing land application areas, <br /> developers and the Discharger sampled groundwater monitoring wells. That data is described in <br /> WDRs Order No. R5-2005-0045. Because no new land application areas are included with this <br /> WDRs revision, the data is not presented here. The Discharger is continuing to sample <br /> groundwater monitoring wells and is submitting quarterly groundwater monitoring reports. Prior <br /> to any authorization to add new land application areas,the Discharger must present further <br /> groundwater analysis in future RWER submittals. <br /> 63.64. To further characterize groundwater quality, the Discharger performed 40 direct push boreholes <br /> to collect soil and groundwater samples. The locations of the direct push sample locations are <br /> described in "Rs Order No. R5-2005-0045. The direct push boreholes samples were collected <br /> between 15 and 17 November 2004, and were typically collected from a depth of 13 to 20 feet <br /> bgs. The direct push groundwater sample data is available in the previous Order for use in <br /> preparing RWER submittals. <br /> 64-65 I D <br /> epth to groundwater varies depending on location, season, and local influences such as irrigation <br /> practices, groundwater extraction, and the presence and stage of surface water bodies. The area <br /> of development covered by this Order can be divided into three subareas: River Islands, <br /> Mossdale_, and the Reiter land application area. River Islands is bounded to the north and west <br /> by Old River,to the east by the San Joaquin River, and to the south by Paradise Cut. The <br /> Mossdale area is bounded to the west by the San Joaquin River. The Reiter land application area <br /> is located approximately two miles east of Mossdale and is less influenced by surface water <br /> bodies; however, an unlined irrigation canal exists approximately 500 feet to the east. <br /> 666 I G <br /> roundwater conditions at the River Islands area can be summarized as follows: <br /> a. Groundwater is typically observed within 12 feet of the ground surface and varies seasonally, <br /> rising to within two-feet of the ground surface during late spring/summer, and declining to a <br />
