Support for Updating the 2012 Material Disposal Area (MDA) C Corrective Measures Evaluation Report

LOCATION: Los Alamos National Laboratory, NM

CLIENT: Newport Nuclear News BWXT – Los Alamos (N3B)

Material Disposal Areas (MDA) C and L are historic disposal sites which have contributed to groundwater and vadose zone contaminant plumes. Some of the contamination is radioactive. Under the RCRA Consent Order between the US Department of Energy and the New Mexico Environment Department, annual reports are required to document the status of the contaminant plumes. To fulfill the RCRA Consent Order reporting requirements, the BGI Team was tasked to prepare the required reports. The reports include 3-D plume modeling, Tier I and Tier II risk Screening Levels to compare against monitoring data, and landfill cover design and implementation evaluation.
