Comments

Alluvial groundwater and the uppermost aquifer were contaminated during uranium processing. A risk analysis indicated no unacceptable risk to human health or the environment. A proposed groundwater compliance action plan has been submitted by DOE to NRC and the state of Utah for concurrence. It recommends application of supplemental standards for the alluvial groundwater (not an aquifer due to low yield), and no remedial action for the uppermost aquifer and the use risk based alternate concentration limits for arsenic, nitrate, selenium, and uranium. The plume area was estimated in 2003.
