65 feet bgs. The screen slot size is 0.010-inch. Drill cuttings from the overdrilling operation will <br /> be stored temporarily on the site in DOT 55-gallon steel drums. <br /> Monitoring Well Surveying and Development <br /> Groundwater monitoring well MW4R will be developed prior to the next scheduled groundwater <br /> monitoring event. Approximately 10 casing volumes of groundwater will be purged from the well <br /> and stored on-site in 55-gallon drums. <br /> The elevation of the replacement well will be re-surveyed to State standards prior to the next <br /> sampling event. The latitude and longitude of the well casing are expected to be within an inch <br /> or two of the surveyed location of MW4, the well replaced by MW4R. <br /> Scheduling <br /> Cardno ATC is currently permitting and scheduling the installation of a shallow-screened <br /> observation well and a deep-screened observation well for purposes of conducting a pilot test <br /> for the remediation of Cr"in groundwater. The observation well installation is scheduled for the <br /> first week of June 2015, and Cardno ATC would like to replace MW4 during the same <br /> mobilization. The RWQCB will be notified in advance of conducting any field activities once the <br /> schedule is confirmed. <br /> If you have any questions, please contact our office at (209) 579-2221. <br /> Respectfully Submitted, <br /> Cardno ATC <br /> James Kundert <br /> Staff Geologist QPp¢ESSIp,�,q <br /> �O JEANNE . <br /> HOM�!EYV �. <br /> No 047410 r`r <br /> n;. <br /> J nne Hornsey, P.E <br /> CA Professional Engineer No. 47410 d'p CIVIL. <br /> Attachments 9 �F CA1�F�Q <br />
