PROJECT/TASK DESCRIPTION. Groundwater cleanup in the SGV/ SFV is a partnership between USEPA, RWQCB, the California Department of Toxic Substances Control (DTSC), and CD PH. Under the Superfund program, USEPA must attempt to identify potentially responsible parties to assume responsibility for identification and cleanup of source areas. To meet the ultimate goal of regional groundwater cleanup, existing sources of contaminati on must be identified and mitigated. Assembly Bill 1803, passed in 1983, required the CD PH to direct the major groundwater users within SGV/ SFV to collect samples for VOC analyses. The RWQCB WIP was an extension of the activities mandated in Assembly Bill 1803. The objectives of the WIP were to: Identify the sources of chemical contamination in groundwater . Assist USEPA with the identification of potentially responsible parties. Oversee the cleanup of contaminant sources. In the late 1980s, RWQCB and USEPA entered into Cooperative Agreements for the SGV and SFV (the SGV agreement ended in 20 10). The goals of the agreements wer e to: Accelerate the identification, assessment, and mitigation of groundwater contamination sources in the SFV and SGV Superfund sites. Augment the RWQCB’s existing source identification program. Coordinate and encourage local entities ’ efforts to identify, assess , and mitigate sources of groundwater pollution. The WIP has been merged into the Site Cleanup Program. Therefore, the forme r WIP cases and the RWQCB and USEPA Cooperative Agreement are managed in the Site Cleanup Program.
PROJECT/TASK DESCRIPTION. When a site enters the program, the BVCP reviews existing site assessment reports and determines whether or not additional investigation or cleanup is required to meet state standards. The site investigation and any necessary cleanup are conducted by the applicant or their consultants and contractors. Site assessment reports, remedial action plans and a final report are submitted to the BVCP for review and approval. When the BVCP is satisfied that the cleanup has met the objectives, the department provides the applicant with a Certification of Completion or "No Further Action Letter" signed by the Director of the Hazardous Waste Program. Applicants pay for the BVCP's oversight costs, which are calculated on an hourly basis. Participation in the program is voluntary and applicants may withdraw at any time. Activities that may be conducted under this QAPP and with the oversight of the BVCP include site characterization, remedial action and risk management. These activities will be documented through work plans for site characterization, characterization reports, risk assessment reports, remedial action plans (RAP), risk management plans (RMP), and final reports, all submitted to the BVCP for review and approval. The following include the necessary components for work plans to conduct environmental data collection submitted for BVCP approval and the necessary QA/QC documentation to be submitted after data collection.
PROJECT/TASK DESCRIPTION. The overall objective of this project is to provide information to be used in development of a TMDL for mercury for the Xxxxxxxxx River Watershed, which includes the Xxxxxxxxx River, several smaller tributaries, and four reservoirs in the Upper Xxxxxxxxx watershed. The major tasks supported by this QAPP include the following:
PROJECT/TASK DESCRIPTION. 6.1 Work Statement and Produced Products This element of the project will consist of three primary tasks including sampling, analysis, and reporting. Sampling will be focused on the water column for chemistry and toxicity. In total, there will be thirty sites randomly distributed in marinas throughout the San Diego region. Water column samples will be collected at three depths (surface, mid-depth, and bottom) for chemical measurements of copper. An additional surface water sample at each site will be collected for toxicity analysis using larvae of the bivalve Mytilus galloprovincialis. The product for this task will be a sampling summary memo indicating sampling success and field observations at each site visited during the field program. The second task will involve laboratory analysis. Laboratory analysis includes chemical measurements of copper in seawater. Laboratory analysis also includes toxicity testing using larvae of the bivalve Mytilus galloprovincialis. The product for this task will be a laboratory analysis summary memo indicating analytical success for all samples delivered to laboratory. The final task will be reporting. This task involves information management, data analysis, and a final report. Information management will ensure consistency with the State’s Surface Water Ambient Monitoring Program (SWAMP). Report writing will provide a description of all methods, tabulations of raw data, and interpretation of results. The product for this task will include a SWAMP compliant relational database for study results (including metadata) and a written final report.
PROJECT/TASK DESCRIPTION. A6.1 Task Summary Basic tasks that are required to implement this SAP/QAPP include collecting duff and tree bark samples from within a two mile buffer of the NPL boundary, with the exception of the area located to the east of Kootenai Falls, and analyzing these samples for asbestos. The area east of Kootenai Falls will be sampled as part of an effort conducted specifically to support OU7. These basic tasks are described in greater detail in subsequent sections of this SAP/QAPP.
PROJECT/TASK DESCRIPTION. The TBWC Water Quality Monitoring Program will implement both long-term and source area sampling to evaluate the condition of Tomales Bay and tributary streams, and the GWRP will augment pre-restoration water quality monitoring efforts by conducting during- and post- restoration water quality monitoring around both impact and control or xxxxx reference sites. Field parameters will be measured at each sampling site. Laboratory parameters to be measured will vary with project site and will depend on particular pollutant(s) of interest for monitoring. A list of parameters of interest is included in Table A-8. Logistical constraints, including personnel availability, sample holding time and laboratory hours of operation will limit the number of sites, and the days and storm events that can be sampled. The duration of current funding also limits the long-term data collection objectives laid out in the Project monitoring plan. Each of these constraints has been considered in the project design, and addressed, to the extent possible, to minimize any impacts. Parameters of Interest Table A-8.
