Independent Technical Review of the Interim Measure Alternatives Analysis for Chromium Contamination in Groundwater at Los Alamos National Laboratory, New Mexico

The two example scenarios described in the report are built around either boundary condition modification or pump and treat. Boundary condition modification focuses primarily on aggressively reducing the driving force of water that is moving Cr(VI) through the subsurface system at LANL, carefully monitoring hydrologic responses, and quantifying natural attenuation rates in key portions of the plume. This scenario would provide a measurable impact on subsurface hydrology using relatively low-cost methods and emphasizing data collection to support the CME process. The second scenario focuses on active removal of Cr(VI) using pump and treat combined with a variety of data collection activities. This scenario would also include some boundary condition modification and would provide more timely impacts in the mid-plume area. However, it is substantially more costly and faces more significant logistical, regulatory, and data interpretation hurdles. Because of these issues and challenges, the pump and treat based scenario would be appropriate primarily for the case in which Cr(VI) removal and more rapid near-term impacts in the mid-plume are considered to be high, overriding priorities. We recommend careful consideration of the advantages and disadvantages of different “combined remedy” IM scenarios and urge the LANL team and its regulators and stakeholders to assemble and select a scenario that is implementable and that provides useful and actionable data to inform and support the CME. Both of the example scenarios presented meet these criteria.

Understanding Building Energy Use in Rural West Texas and Oklahoma and Southern New Mexico: Basic Building Stock Characterization

This report is part of a publication series that focuses on approximately 100 different local geographies, or "clusters." Each report provides commercial and multifamily building characteristic and energy data for a local geography, with the intention of helping policymakers at the city, county and state levels better understand building energy use. Specifically, this report breaks down the building stock in the counties shown in Figure 1 by building type, size, energy consumption, and emissions.

Understanding Commercial Building Energy Use in Rural West Texas and Oklahoma and Southern New Mexico: Building Stock Segmentation for Retrofit Planning

This report is part of the second phase of a publication series focusing on approximately 100 different local geographies, or "clusters." Each report provides characteristic features and energy data for commercial buildings in a specific area to help policy makers at the city, county, and state level better understand building energy use and emissions. This report breaks down the energy consumption and emissions of the building stock in the counties shown in Figure 2 by building type, building size, end use, energy consumption, emissions, and segment.

Understanding Multifamily Energy Use in Rural West Texas and Oklahoma and Southern New Mexico: Building Stock Segmentation for Retrofit Planning

This report is an addendum to a publication series that focuses on approximately 100 different local geographies, or "clusters". This addendum expands the report series to include large multifamily building characteristics as well as energy and emission data for each local geography. The intention of this addendum is to help policymakers at the city, county, and state levels better understand building energy use and emissions in large multifamily buildings.
