1 . . <br /> • <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. R5-2008-0149-005 <br /> FOR <br /> IN-SITU GROUNDWATER REMEDIATION AT SITES WITH VOLATILE ORGANIC <br /> COMPOUNDS, NITROGEN COMPOUNDS, PERCHLORATE, PESTICIDES, <br /> SEMI-VOLATILE COMPOUNDS AND/OR PETROLEUM HYDROCARBONS <br /> CONTINENTAL GRAIN COMPANY <br /> SAN JOAQUIN COUNTY <br /> This Monitoring and Reporting Program (MRP) describes requirements for monitoring a <br /> groundwater extraction and treatment system. This MRP is issued pursuant to Water Code <br /> Section 13267. The Discharger shall not implement any changes to this MRP unless and until <br /> a revised MRP is issued by the Executive Officer. As appropriate, California Regional Water <br /> Quality Control Board, Central Valley Region (Central Valley Water Board) staff shall approve <br /> specific sample station locations prior to implementation of sampling activities. This Monitoring <br /> and Reporting Program is in addition to routine groundwater monitoring prescribed by <br /> Monitoring and Reporting Program No. R5-2007-0826. <br /> All samples should be representative of the volume and nature of the discharge or matrix of <br /> material sampled. The time, date, and location of each grab sample shall be recorded on the <br /> sample chain of custody form. <br /> GROUNDWATER MONITORING <br /> As shown on Attachment A, there are 17 monitor wells, 2 extraction wells, and 2 injection wells <br /> associated with this site. Only the wells listed in Table 1 are associated with the groundwater <br /> treatment system. The groundwater monitoring program for the wells listed in Table 1 and any <br /> treatment system wells installed subsequent to the issuance of this MRP, shall follow the <br /> schedule below. When sampling required by this MRP is duplicative of sampling required by <br /> separate MRP issued to the Discharger, one sample and analysis can satisfy the requirements <br /> of both MRPs. The volume of extracted groundwater shall also be provided in quarterly <br /> monitoring reports. Sample collection and analysis shall follow standard EPA protocol. <br /> The monitoring wells, extraction wells and/or injection wells shall be sampled according to the <br /> schedule in Table 1 and the samples analyzed by the methods in Table 2, as shown on the <br /> following page. <br />
