Mr. Geoff Rader, RWQCB <br /> August 28, 2017 <br />Work Plan for Offsite Monitoring Well Installation Project No. 2129-1140-01 <br />1120 West Hammer Lane, Stockton, CA <br />Page 4 <br />Task 2D: Waste Management <br />Soil cuttings, auger rinseate water, and well development water will be placed in <br />55-gallon steel drums, appropriately labeled, and temporarily stored at the site pending <br />disposal characterization. A licensed contractor will transport the soil and wastewater to <br />an appropriate facility for disposal shortly following the investigation. <br />Task 2E: Analytical Testing <br />Soil and groundwater samples will be forwarded to a state-certified analytical laboratory <br />for chemical analysis under proper chain-of-custody. The samples will be analyzed for <br />gasoline range organics (GRO) using EPA Method 8015, and for benzene, toluene, <br />ethylbenzene, and total xylenes (BTEX compounds), methyl tertiary butyl ether (MTBE), <br />naphthalene, 1,2-dibromoethane (EDB), and 1,2-dichloroethane (1,2-DCA) using EPA <br />Method 8260. <br />Task 3: Well Installation Report <br />A well installation report will be prepared documenting findings of the drilling activities, <br />and will include, but not be limited to, a scaled site plan, boring logs, well construction <br />details, certified analytical results, and will document any modifications from this Work <br />Plan. The report will be submitted within approximately four weeks of receiving all <br />analytical results. <br />SCHEDULE <br />Following approval of this Work Plan, an access agreement will be sent to the owner of <br />the property north-northeast of the site. If permission to install well MW-13 on this <br />property can be obtained, the work will promptly be scheduled once a drilling permit is <br />obtained from SJCEHD. If the property owner refuses access to complete the work, than <br />an encroachment permit application package will be submitted to the City of Stockton <br />Public Works Department. Based on historical experience, we believe approximately 2 <br />to 3 months would be necessary to obtain the encroachment permit, which would delay <br />installation of MW-13 until early 2018. <br />LIMITATIONS <br />This document was prepared in general accordance with accepted standards of care that <br />existed at the time this work was performed. No other warranty, expressed or implied, is <br />made. Conclusions and recommendations are based on field observations and data <br />obtained from this work and previous investigations.
