Title: Characterization recommendations for waste sites at the Savannah River Plant

Abstract

One hundred and sixty six disposal facilities that received or may have received waste materials resulting from operations at the Savannah River Plant (SRP) have been identified. These waste range from innocuous solid and liquid materials (e.g., wood piles) to process effluents that contain hazardous and/or radioactive constituents. The waste sites have been grouped into 45 categories according the the type of waste materials they received. Waste sites are located with SRP coordinates, a local Department of Energy (DOE) grid system whose grid north is 36 degrees 22 minutes west of true north. DOE policy is to close all waste sites at SRP in a manner consistent with protecting human health and environment and complying with applicable environmental regulations (DOE 1984). A uniform, explicit characterization program for SRP waste sites will provide a sound technical basis for developing closure plans. Several elements are summarized in the following individual sections including (1) a review of the history, geohydrology, and available characterization data for each waste site and (2) recommendations for additional characterization necessary to prepare a reasonable closure plan. Many waste sites have been fully characterized, while others have not been investigated at all. The approach used in this report ismore » to evaluate available groundwater quality and site history data. For example, groundwater data are compared to review criteria to help determine what additional information is required. The review criteria are based on regulatory and DOE guidelines for acceptable concentrations of constituents in groundwater and soil.« less

  • One hundred and sixty six disposal facilities that received or may have received waste materials resulting from operations at the Savannah River Plant (SRP) have been identified. These waste range from innocuous solid and liquid materials (e.g., wood piles) to process effluents that contain hazardous and/or radioactive constituents. The waste sites have been grouped into 45 categories according the the type of waste materials they received. Waste sites are located with SRP coordinates, a local Department of Energy (DOE) grid system whose grid north is 36 degrees 22 minutes west of true north. DOE policy is to close all wastemore » sites at SRP in a manner consistent with protecting human health and environment and complying with applicable environmental regulations (DOE 1984). A uniform, explicit characterization program for SRP waste sites will provide a sound technical basis for developing closure plans. Several elements are summarized in the following individual sections including (1) a review of the history, geohydrology, and available characterization data for each waste site and (2) recommendations for additional characterization necessary to prepare a reasonable closure plan. Many waste sites have been fully characterized, while others have not been investigated at all. The approach used in this report is to evaluate available groundwater quality and site history data. For example, groundwater data are compared to review criteria to help determine what additional information is required. The review criteria are based on regulatory and DOE guidelines for acceptable concentrations of constituents in groundwater and soil.« less
  • The PATHRAE computer code was used for the contaminated transport, exposure assessment, and human health risk analyses to provide an accepted, broadly applicable and cost efficient method for use on all of the waste sites. The PATHRAE model was developed for performance assessment of low-level radioactive waste disposal technologies. It is a multiple pathway transport and risk assessment code designed to analyze, as a function of time, the exposure doses and resulting health effects to critical population groups and to the off-site population. Recent extensions of the PATHRAE code have permitted the analysis of chemically toxic contaminants, as well asmore » radioactive contaminants, in the various environmental pathways. The types of SRP waste sites analyzed include seepage basins, retention basins, shallow land burial sites, rubble piles, and spill areas. The operational history of the sites varies from over 30 years for some of the solid waste sites and basins, to nearly instantaneous releases for the spill areas. 6 refs., 13 figs., 4 tabs.« less
  • This report, which consists of a main report and 26 appendix reports, documents the contribution to the Environmental Information Document (EID) effort. Specifically, the main report describes, in detail, the methodology (models, data, assumptions, and procedures) of the atmospheric contaminant transport analysis and human health risk assessment of SRP waste sites, and it includes tables that summarize the assessment data, procedures, and results. Each individual appendix report contains text that documents, in site-specific terms, the methodology used in the analysis of that waste site functional grouping; and a set of comprehensive tables that quantify, for each of the waste sitesmore » in the grouping, the atmospheric source terms, air concentrations (for calculating worker exposures), air-related pathway exposures, and risks associated with the cleanup options for the waste site(s). Each appendix report is a ''stand-alone'' document formatted to facilitate SRL's direct incorporation of the information in the EIDs. 50 refs., 16 figs., 44 tabs.« less
  • The report contains ecologic analyses of closure options for each of 26 functional groups of waste sites at SRP. Some of these waste sites have historically received hazardous, radioactive, or mixed wastes. SRP has been a designated National Environmental Research Park since 1972. In addition, the effect of 30 years of restricted public access has been to make the SRP, in a sense, a wildlife refuge. Contemporaneously with restricted access and production of strategic nuclear materials, there have been increases in wildlife populations, extensive pine planting, and return of formerly agricultural land to natural succession. In preparing this report, Sciencemore » Applications International Corporation (SAIC) utilized data for contaminants in groundwater, surface waters, basin sediments, and waste site soils collected by various contractors and provided by du Pont. In addition, the ecologic assessments are based upon PATHRAE ground water transport modeling performed by Rogers and Associates Engineering, and a stream dilution modeling methodology adopted by du Pont. SAIC did not perform field work in the course of the assessment, but did visit the major sites for cursory visual inspection and examined aerial photographs of waste sites and surrounding terrain. 111 refs., 22 figs., 163 tabs.« less
  • Ecologic assessment of closure options is one of several analyses being documented in the EIDs (along with analysis of relative potential health risks, accident risks, and costs). This information will serve as a basis for choosing the best option for closing a particular waste facility. This report presents the methodology adopted for SRP waste site ecological assessment, and the results of its application. The results of the ecologic assessment indicated that no impacts are expected for any of the closure options at eleven sites. Significant ecologic impacts are possible at the eight waste sites or groups of waste sites includingmore » the Radioactive Waste Burial Grounds, Old TNX Seepage Basin, CMP Pits, F-Area Seepage Basins, H-Area Seepage Basins, SRL Seepage Basins, R-Reactor Seepage Basins, and L-Area Oil and Chemical Basin. 104 refs., 22 figs., 241 tabs.« less
