Abstract

The salt solution produced at the Defense Waste Processing Facility (DWPF) is a low-level hazardous waste and has both corrosive and metal toxicity characteristics. A wasteform was designed to stabilize this solution. The objectives were: to eliminate the hazardous characteristics of the waste; and to minimize the release of potential contaminants, such as NO{sub 3}{sup {minus}}, so that drinking water standards would be maintained for groundwater at the perimeter of the disposal site. The ability to produce the wasteform in high volumes and emplace it in an engineered landfill was also necessary for treating and disposing of the large amount of waste. EP toxicity and TCLP testing was conducted to determine whether various saltstone mixes qualified as nonhazardous according to EPA guidelines. Impact of the design landfill on the groundwater was modeled by numeric methods. Data from laboratory leaching studies, large-scale saltstone lysimeter experiments, and disposal site characterization studies were used in the performance assessment. 9 refs., 3 figs., 3 tabs.

Metal toxicity evaluation of Savannah River Plant saltstone comparison of EP and TCLP test results

Conference Langton, C

Saltstone is the waste treatment and disposal concept for low-level defense waste at the Savannah River Plant. The waste is a sodium salt solution which has about 230 ..mu..CiL in addition to the hazardous characteristics of corrosivity and metal toxicity (Cr/sup +6/ > 100 ppM). Two EPA test procedures are routinely used at SRP to evaluate metal toxicity of wastes and wasteforms. 1) the Extraction Procedure (EP); and 2) the Toxicity Characterization Leaching Procedure (TCLP). The EP test is required by SCDHEC and EPA. The TCLP is used to evaluate the effect of increased surface area on metal leaching frommore »« less

Decommissioning and Environmental Cleanup of a Small Arms Training Facility - 13225

Conference Adams, Karen; Kmetz, Thomas; Smith, Sandra; ...

US DOE performed a (CERCLA) non-time critical removal (NTCR) action at the Small Arms Training Area (SATA) Site Evaluation Area (SEA) located at the Savannah River Site (SRS), in Aiken, South Carolina. From 1951 to May 2010, the SATA was used as a small weapons practice and qualifying firing range. The SATA consisted of 870.1 ha (2,150 ac) of woodlands and open field, of which approximately 2.9 ha (7.3 ac) were used as a firing range. The SATA facility was comprised of three small arms ranges (one static and two interactive), storage buildings for supplies, a weapons cleaning building, andmore »« less

SALTSTONE 2QCY08 TCLP RESULTS

Technical Report Cozzi, A

A Saltstone waste form was prepared in the Savannah River National Laboratory from a Tank 50H sample and Z-Area premix material for the second quarter of calendar year 2008 (2QCY08). After the prescribed 28 day cure, samples of the saltstone were collected, and the waste form was shown to meet the South Carolina Hazardous Waste Management Regulations (SCHWMR) R.61-79.261.24 and R.61-79.268.48(a) requirements for a nonhazardous waste form with respect to RCRA metals and underlying hazardous constituents. These analyses met all quality assurance specifications of USEPA SW-846. The Saltstone Production Facility (SPF) receives waste from Tank 50H for treatment. In themore »« less

SALTSTONE VAULT CLASSIFICATION SAMPLES MODULAR CAUSTIC SIDE SOLVENT EXTRACTION UNIT/ACTINIDE REMOVAL PROCESS WASTE STREAM APRIL 2011

Technical Report Eibling, R.

Savannah River National Laboratory (SRNL) was asked to prepare saltstone from samples of Tank 50H obtained by SRNL on April 5, 2011 (Tank 50H sampling occurred on April 4, 2011) during 2QCY11 to determine the non-hazardous nature of the grout and for additional vault classification analyses. The samples were cured and shipped to Babcock & Wilcox Technical Services Group-Radioisotope and Analytical Chemistry Laboratory (B&W TSG-RACL) to perform the Toxic Characteristic Leaching Procedure (TCLP) and subsequent extract analysis on saltstone samples for the analytes required for the quarterly analysis saltstone sample. In addition to the eight toxic metals - arsenic, barium,more »« less
