Annual Groundwater Monitoring Reports
Groundwater Resources Consultants monitored various source areas both on-site and off-site for groundwater contamination. Over 20 wells were sampled for chemicals including TCE and other Volatile Organic Contaminants (VOCs). Also included in these reports were data from groundwater extraction/treatment activities (e.g., pumping rates and volumes), static water level measurements, and collection and lab analysis of water samples from shallow zone wells and Chatsworth formation wells.
Bimonthly Groundwater Monitoring Reports
Quarterly groundwater monitoring was conducted on-site at Bravo, Canyon, and Delta groundwater extraction/treatment systems. More than fifty wells were sampled for Volatile Organic Compounds (VOCs) and hydrocarbons (common ions, trace metals, chemical parameters specific to SHMP components and residues) and 10 wells were sampled for Base/Neutral and Acid Organic compounds. Selected samples were analyzed for determination of Semi-Volatile Organic Compounds (SVOCs). Soil and rock samples and groundwater samples were taken to determine background levels of naturally occurring radiological parameters (gross alpha, beta, and gamma radioactivity). Some off-site sampling and analysis were conducted as well.
Quarterly Groundwater Monitoring Reports
These reports summarize the results of groundwater monitoring, including groundwater extraction/treatment activities and the reclamation system. Components include: measurement of static water levels, collection of water quality samples from shallow zone wells and Chatsworth Formation wells, collection of water quality samples from treatment system influent and effluent, and tables summarizing water levels and quality. On-site (and SSFL adjacent) sampling concentrated on TCE, Trans-1, 2-DCE, and other Volatile Organic Compounds. Additional information is available regarding regulation guidelines, air stripping towers, chemicals data and analysis, and treatment systems.
Groundwater Remedial Action Plan
Because degraded groundwater resulting from historic product testing activities had been recognized to occur beneath the SSFL facility, Groundwater Resources Consultants developed a Groundwater Remedial Action plan. These plans provide a summary of historic activities at the Facility, a discussion of previous hydrogeologic investigations conducted, a proposed monitoring plan to assess the effectiveness of the GRS to contain, remove, and treat degraded water (GRS= system of extraction wells and treatment plants intended to pump out degraded groundwater and remove organic contaminants), and investigation directed to identify VOCs, especially trichloroethylene (TCE) and trans-1, 2-dichlorethylene (on-site).
Environmental Monitoring Reports, Volume 1
In general, these materials provide Rocketdyne's response to notices of violation received from Ventura Air Pollution Control District (VAPCD) along with the specific steps taken by Rocketdyne to correct the different situations. This includes a number of matters regarding air pollution control, namely: information regarding permits (renewal fees, drafts, etc.), Air Toxic Emission Inventory reports, Renovations (asbestos, etc), Chemical Tracking, Stripping towers, Gas usage, Cooling towers, SARA Toxic Chemical Release Reporting, Fluorocarbons and air sampling for chemicals like TCE and vinyl chloride.
Environmental Monitoring Reports, Volume 2
These reports provide information regarding radiological monitoring of air, soil, ambient radiation levels (on-site and off-site), water (wells and ponds), and surface water run-off. Four broad areas are covered: Radiological, Surface Water, Hazardous Waste Management, and Remediation. A wide range of topics are addressed, including: Remediation, Transported Hazardous Waste, Non-RCRA Wastes, Radioactive Material Disposal Facility, Corrective Action, Former Sodium Disposal Facility, Underground Storage Tanks, Community Outreach, Public Participation Plans, DOE Indoor Radon Monitoring, and Ecological/Bioassay reporting. Also included in these reports are NPDES reports and permits (includes monthly monitoring reports and quarterly domestic wastewater reports), surface water run-off plans (Northwest slope rainfall run-off monitoring program), Asbestos Removal Action Plans for local rock, and reports of violations conducted by DHS and response from Rocketdyne.
Environmental Monitoring Reports, Volume 3
The Volume 3 reports contain information regarding groundwater treatment and monitoring (144 wells on site, 10-13 off-site that are monitored for radiological and chemical presence) as well as radioactivity monitoring in rock formations, soil, and groundwater. On-site wells in Alfa, Canyon, Delta, Bravo, and Bowl groundwater extraction/treatment systems were sampled. Examples of reports included are: SSFL Bimonthly report, Groundwater Radiological Monitoring Proposed and Progress Reports, Chemical analysis reports, and EPA Drinking Water standards. Permits to operate stripping towers were also included.
Hydrogeological and Groundwater Investigations
The three major purposes for these investigations were: 1) to determine the extent of organic constituents in the alluvial groundwater system and in the fractured Chatsworth Formation, 2) to define the hydraulic relationships between the alluvial groundwater system at SSFL and the underlying Chatsworth Formation, and 3) to characterize the hydrogeology of the SSFL site and surrounding environs in sufficient detail to recommend appropriate remedial actions. Results and analysis for these topics are provided in the following reports. Also included are hydrogeological assessment reports for 5 surface water impoundment areas at the SSFL (in accordance/response with the Toxic Pits Cleanup Act of 1984), detailed data on waste characteristics, surface water and groundwater quality, well construction data, water level data, quality assurance (with illustrations and maps), results from the investigation of soil and shallow groundwater in area IV.
Annual
Site Environmental Reports (ASER)
The ASER Reports contain information such as: radiological and non-radiological environmental monitoring information related to ETEC and other Department of Energy contracted operations at Rocketdyne facilities, sampling results for SSFL and De Soto sites (on-site and off-site), descriptions of environmental programs, such as sampling and sample preparation, facility descriptions, compliance status, and environmental sampling information on air, water, rock and soil, vegetation, wildlife, and radiation/ ambient radiation.
Multi-Media Sampling at Brandeis-Bardin Institute and the Santa Monica Mountains Conservancy
In order to determine whether chemicals or radionuclides had spread to neighboring properties, a workplan, along with results and analysis for evaluating the Brandeis-Bardin Institute and Santa Monica Mountains Conservancy properties, was developed and conducted. The two main purposes for this project were 1) to determine representative levels of chemicals or radionuclides of potential concern present in local background areas and areas of the Brandeis-Bardin and Conservancy properties and 2) to make statistical comparisons to determine if the study properties have significantly elevated levels of chemicals or radionuclides of potential concern relative to background levels. Topics of study included: sampling of soil, surface water, groundwater, fruit and vegetable sampling, quality assurance/quality control (QA/QC) and laboratory analysis (environmental media evaluated). With all of the reports considered, the following substances were measured: Tritium, VOCs, Gross alpha and beta radiation, gamma radiation, Iodine-129, Isotopic Plutonium, Metals, and Semi-Volatile Organic Compounds (SVOCs).
These studies concentrated on on-site groundwater and bedrock core samples. Reports include details of coring operation and groundwater investigation and results of testing for chemicals and metals, such as TCE, hydrocarbons, and lead.
National Pollutant Discharge Elimination System (NPDES) Annual Reports
These annual reports summarize analytical data collected during the discharge of surface water from SSFL through seven outfall locations and Area I and Area III sewage treatment plants, as authorized by NPDES permits. The investigations explored the areas for radioactivity, metals, pesticides, volatile organics, semi-volatiles, and base/neutral/acid extractibles.
National Pollutant Discharge Elimination System (NPDES): Monitoring Report Submittals
NPDES Monitoring Report submittals, presented to the Regional Water Quality Control Board, summarize analytical data collected during the discharge of surface water from the SSFL through all outfalls as authorized by NPDES Permit No. CA0001309. Also included in each report is a summary of sewage treatment plant monitoring activity for the month.

Radiological Characterization Survey
The purpose of the survey was to locate and characterize any previously unknown areas of elevated radioactivity in Area IV. The study provided a comprehensive investigation of the radiological status of regions in Area IV which had not previously been characterized-focused on regions which were thought to be free of radioactive contamination and thus had not previously been surveyed. Three methods were used: ambient gamma survey, walk-about gamma survey, and soil sampling and analysis.
