OSTI ID:10140936

The US Environmental Protection Agency (EPA) has established health and environmental protection regulations to correct and prevent groundwater contamination resulting from processing activities at inactive uranium milling sites (40 CFR Part 192). According to the Uranium Mill Tailings Radiation Control Act of 1978, (UMTRCA) (48 CFR 590), the US Department of Energy (DOE) is responsible for assessing the inactive uranium processing sites. The DOE has determined that this assessment shall include information on hydrogeologic site characterization. The water resources protection strategy that describes how the proposed action will comply with the EPA groundwater protection standards is presented in Attachment 4. Site characterization activities discussed in this attachment include the following: Characterization of the hydrogeologic environment, including hydro-stratigraphy, groundwater occurrence, aquifer parameters, and areas of recharge and discharge. Characterization of existing groundwater quality by comparison with background water quality and the maximum concentration limits (MCLs) of the proposed EPA groundwater protection standards. Definition of physical and chemical characteristics of the potential contaminant source, including concentration and leachability of the source in relation to migration in groundwater and hydraulically connected surface water. Description of local water resources, including current and future use and value, availability, and alternative supplies.
