At a minimum, the workplan shall include a proposal for (a) a review of historical hydrogeologic data produced by Nestle, (b) short-term coordinated monitoring of shallow groundwater monitoring wells at the City's site, the Fox River Paper Products facility, and the Nestle facility, (c) monitoring of the Stanislaus River stage coordinated with shallow groundwater monitoring, and (d) a review of the specific inadequacies of the City's current groundwater monitoring network. The workplan shall clearly identify and detail the monitoring network and data that will be used in the evaluation. • By 1 September 2004, the City shall submit (a)the results of the Hydrogeologic Evaluation and (b) a Monitoring Well Installation Workplan. The Hydrogeologic Evaluation results should include a detailed hydrogeologic interpretation of the shallow groundwater zone in the vicinity of the site, describe and provide the rationale for the placement of a sufficient number of additional groundwater monitoring wells to allow evaluation of the groundwater quality upgradient,beneath, and downgradient of the site, and include a long-tern monitoring program that will provide the data necessary to assess compliance with the Groundwater Limitation of the WDRs. The Monitoring Well Installation Workplan should provide detailed plans for the installation of wells proposed in the Hydrogeologic Evaluation. Every monitoring well must be constructed to yield representative samples from the uppermost layer of the uppermost water bearing zone and to comply with applicable well standards. The workplan should be consistent with, and include the items listed in, the first section of the enclosed document,Items to be Included in a Monitoring Well Installation Workplan and a Monitoring Well Installation Report of Results. All wells shall be installed no later than 1 November 2004, and samples from these wells shall be included as part of the 4t° Quarter 2004 monitoring event. • By 15 December 2004, the City shall submit a Monitoring Well Installation Report of Results. The report should be consistent with, and include the items listed in, the second section of the enclosed document,Items to be Included in a Monitoring Well Installation Workplan and a Monitoring Well Installation Report of Results. The report should describe the installation and development of the monitoring wells and explain any deviation from the approved workplan. California Environmental Protection Agency 0 Recycled Paper
