Hanford Site ground-water monitoring for January through June 1988
The Pacific Northwest Laboratory monitors ground-water quality at the Hanford Site for the US Department of Energy to assess the impact of Site operations on the environment. Work undertaken between January and June 1988 included monitoring ground-water elevations across the Site, and monitoring hazardous chemicals and radionuclides in ground water. Water levels continued to rise in areas receiving increased recharge (e.g., beneath B Pond) and decline in areas where the release of water to disposal facilities has been terminated (e.g., U Pond). The major areas of ground-water contamination defined by monitoring activities are (1) carbon tetrachloride in the 200-West Area; (2) cyanide in and north of the 200-East and 200-West Areas; (3) hexavalent chromium contamination in the 100-B, 100-D, 100-F, 100-H, 100-K, and 200-West Areas; (4) chlorinated hydrocarbons in the vicinity of the Solid Waste Landfill and 300 Area; (5) uranium in the 100-F, 100-H, 200-West, and 300 Areas; and (6) tritium and nitrate across the Site. In addition, several new analytical initiatives were undertaken during this period. These include cyanide speciation in the BY Cribs plume, inductively coupled argon plasma/mass spectrometry (ICP/MS) measurements on a broad selection of samples from the 100, 200, 300, and 600 Areas, and high sensitivity gas chromatography measurements performed at the Solid Waste Landfill-Nonradioactive Dangerous Waste Landfill. 23 figs., 25 tabs.
