Title: Quarterly Groundwater Report for the Solid Waste Landfill October - December 2006

Abstract

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 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 K Basins during October, November, and December 2006. Conditions remained 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 months as a consequence of new wells having been installed near KW Basin as part of a pump-and-treat system for chromium contamination, and new wells installed between the KE Basin and the river to augment long-term monitoring in that area.
  • The primary objective of this project is to provide design criteria for a volume reduction system to treat combustible solids and liquids generated in the nuclear fuel cycle. Progress has been made in each of the major areas of interest. Primary emphasis has been in the design and purchasing of equipment for liquid feed mechanisms and in evaluating technology available for compaction of empty waste containers. Contacts have been made with several commercial firms involved in various areas of the nuclear industry such as fuel reprocessing, handling and transportation, architectural engineering, and electric power. Firms in all these areas havemore » expressed a strong general interest in the Cyclone Incinerator. Details will be made available as commitments are made. Efforts are being made with each of these firms to characterize their wastes and determine volumes involved.« 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
