Title: Quarterly Groundwater Report for the Solid Waste Landfill July - September 2006

Abstract

This report provides information on groundwater monitoring at the Solid Waste Landfill during the quarterly time period July to September 2006. Conditions remain very similar to those reported in the previous quarterly report. Six background threshold values, one WAC 173-200 Groundwater Quality Criterion, and one WAC 246-290-310 Maximum Contaminant Level were exceeded. The results that exceed applicable limits are consistent with the type of waste disposed to the landfill including sewage and chlorinated hydrocarbons from either the sewage or the 1100 Area heavy equipment garage and bus shop.

  • This report provides information on groundwater monitoring at the Solid Waste Landfill during the quarterly time period October through December 2006. Conditions remain very similar to those reported in the previous quarterly report. Four background threshold values, two WAC 173-200 Groundwater Quality Criteria, and one WAC 246-290-310 maximum contaminant level were exceeded. The results that exceed applicable limits are consistent with the type of waste disposed to the landfill.
  • This report provides information about RCRA groundwater monitoring for the period July through September 2006. Eighteen Resource Conservation and Recovery Act (RCRA) sites were sampled during the reporting quarter.
  • This report provides information on groundwater monitoring at the K Basins during July, August, and September 2006. Conditions remain very similar to those reported in the previous quarterly report, with no evidence in monitoring results to suggest groundwater impact from current loss of basin water to the ground. The K Basins monitoring network will be modified in the coming quarters as a consequence of remedial action at KE Basin, i.e., removal of sludge and basin demolition.
  • Progress during the reporting period of July-- September 1973 on three transuranic solid waste management research programs funded by the AEC Division of Waste Management and Transporttion is given. The three programs include transuranic solid waste management research and development, the contaminated waste treatment development facility, and the burial grounds evaluation. The interim storage criteria are now ready to be issued for general review. Experiments in radiolysis and container corrosion have been reorganized and expanded to provide information for optimization of interim storage, while waste sorting experiments have begun to determine more accurately the character of wastes being produced atmore » LASL. Several task forces have been organized for the waste treatment facility to evaluate incinerators and determine a satisfactory operational size for the facility. Work has begun on developing a model for the risk analysis of radioactive burial grounds. A questionnaire has been developed to obtain the necessary information for the analysis. (auth)« less
  • The Solid Waste Landfill (SWL) is regulated by the Washington State Department of Ecology under WAC 173-304. Between 1973 and 1976, the landfill received primarily paper waste and construction debris, but it also received asbestos, sewage, and catch tank liquid waste. Groundwater monitoring results indicate the SWL has contaminated groundwater with volatile organic compounds and possibly metals at levels that exceed regulatory limits. DynCorp, Tri-Cities, Inc. operates the facility under an interim closure plan (final closure plan will be released shortly). Pacific Northwest National Laboratory (PNNL) monitors groundwater at the site. This monitoring plan includes well and constituent lists, andmore » summarizes sampling, analytical, and quality control requirements. Changes from the previous monitoring plan include elimination of two radionuclides from the analyte list and some minor changes in the statistical analysis. Existing wells in the current monitoring network only monitor the uppermost portion of the upper-most aquifer. Therefore, two new downgradient wells and one existing upgradient well are proposed to determine whether groundwater waste constituents have reached the lower portion of the uppermost aquifer. The proposed well network includes three upgradient wells and ten downgradient wells. The wells will be sampled quarterly for 14 analytes required by WAC 173-304-490 plus volatile organic compounds and filtered arsenic as site-specific analytes.« less
