This document evaluates potential impacts to public health and the environment resulting from ground water contamination at the former uranium mill processing site. The tailings and other contaminated material at this site were placed in a disposal cell on the site in 1989 by the US DOE`s Uranium Mill Tailings Remedial Action (UMTRA) Project. Currently, UMTRA Project is evaluating ground water contamination in this risk assessment.

From abstract: In 1985, 1986, and 1988, the U.S. Bureau of Mines and the U.S. Geological Survey studied the Desolation Canyon (UT-060-068A), Turtle Canyon (UT-060-067), and Floy Canyon (UT-060-068B) Wilderness Study Areas, which are contiguous and located in Carbon, Emery, and Grand Counties in eastern Utah. The study areas include 242,000 acres, 33,690 acres, and 23,140 acres respectively. Coal deposits underlie the Desolation Canyon, Turtle Canyon, and Floy Canyon study areas.

The purpose of this water sampling and analysis plan (WSAP) is to provide a basis for groundwater and surface water sampling at the Green River Uranium Mill Tailing Remedial Action (UMTRA) Project site. This WSAP identifies and justifies the sampling locations, analytical parameters, detection limits, and sampling frequency for the monitoring locations.

This document presents the US DOE water resources protection strategy for the Green River, Utah mill tailings disposal site. The modifications in the original plan are based on new information, including ground water quality data collected after remedial action was completed, and on a revised assessment of disposal cell design features, surface conditions, and site hydrogeology. All aspects are discussed in this report.
