Radiological survey report for the Weldon Spring Quarry

Technical Report · Sun Sep 01 04:00:00 EDT 1985

OSTI ID:5054377

The Weldon Spring Site (WSS) is a US Department of Energy surplus facility comprising the Quarry, Raffinate Pits, Chemical Plant, and vicinity properties. Radiological characterization of the WSS is being conducted in four phases: the Raffinate Pits facility, Quarry, Chemical Plant, and the vicinity properties. Bechtel National, Inc. and its radiological support contractor, Eberline Analytical Corporation, conducted a radiological characterization survey of the Raffinate Pits in 1982 and 1983; the survey of the Quarry described in this document represents the second phase of the work and was performed in 1984 and 1985. The survey consisted of direct beta-gamma surface readings, near-surface gamma readings, exposure level measurements, radon emission rate measurements, and gamma logs of boreholes. Samples of surface soils, subsurface soils, surface water, and groundwater were collected. These samples were analyzed for selected radionuclides in the uranium and thorium natural decay chains. This report describes the radiological and chemical characterization of the Quarry, the procedures used to conduct the survey, and the survey results. Estimates based on the radiological data indicate that 95,000 yd/sup 3/ of surface and subsurface materials at the Quarry are contaminated in excess of DOE guidelines; concentrations of radionuclides in sediment from the Quarry pond were approximately 100 times background. Soil samples were not hazardous as defined by the Resource Conservation and Recovery Act, but varying concentrations were found of chemicals classified as priority pollutants by the Environmental Protection Agency. Concentrations of uranium in groundwater exceeded DOE guidelines; however composites of water from the Quarry pond showed uranium concentrations only slightly in excess of the guideline. 15 refs., 14 figs., 8 tabs.
