Chromium Plume Control Interim Measure and Plume-Center Characterization, Los Alamos National Laboratory, Los Alamos, NM

In this Environmental Assessment (EA), the Department of Energy (DOE) proposes to address chromium contamination in the groundwater beneath Mortandad Canyon at Los Alamos National Laboratory (LANL) located in Los Alamos, New Mexico. Groundwater sampling data show the presence of chromium contamination in the regional aquifer resulting from historical use of potassium dichromate – a corrosion inhibitor – in non-nuclear cooling-tower water that was discharged to an outfall as part of operational maintenance activities. DOE’s proposed action is to implement an interim measure that would control offsite migration of the chromium groundwater plume off LANL lands and to evaluate the feasibility of remedial actions to potentially remediate the chromium plume.
