Results of Tritium Tracking and Groundwater Monitoring at the Hanford Site 200 Area State-Approved Land Disposal Site--Fiscal Year 2000

The Hanford Site 200 Area Effluent Treatment Facility (ETF) processes contaminated liquids derived from Hanford Site facilities. Groundwater monitoring for tritium and other constituents is required by the state-issued permit at 22 wells surrounding the facility. Water level measurements in nearby wells indicate that a small hydraulic mound exists around the SALDS facility as a result of discharges. Evaluation of this condition indicates that the network is currently adequate for tracking potential effects of the SALDS on the groundwater. During FY 2000, average tritium activities in most wells declined from average activities in 1999. The exception was deep well 699-48-77C, where tritium results were at an all-time high (710,000 pCi/L) as a result of the delayed penetration of effluent deeper into the aquifer. Of the 12 constituents with permit enforcement limits, which are monitored in SALDS proximal wells, all were within groundwater limitations during FY 2000. Analyses for conductivity, total dissolved solids, sulfate, chloride, sulfate, dissolved calcium, and dissolved sodium indicate that well 699-48-77A and, to a lesser extent, well 699-48-77D show the effects of dilute effluent entering groundwater, resulting in a depression of concentrations of these constituents below natural background levels. Recommendations for future monitoring include temporarily increasing the …

Pacific Northwest National Laboratory Institutional Plan FY 2000-2004 (open access)

Pacific Northwest National Laboratory Institutional Plan FY 2000-2004

The Pacific Northwest National Laboratory Institutional Plan for FY 2000-2004 sets forth the laboratory's mission, roles, technical capabilities, and laboratory strategic plan. In the plan, major initiatives also are proposed and the transitioning initiatives are discussed. The Programmatic Strategy section details our strategic intent, roles, and research thrusts in each of the U.S. Department of Energy's mission areas. The Operations/Infrastructure Strategic Plan section includes information on the laboratory's human resources; environment, safety, and health management; safeguards and security; site and facilities management; information resources management; management practices and standards; and communications and trust.
