Detailed Analysis of Alternatives Report. Version 2.0. Soils DAA. Volume 4.
Abstract
The analysis of remedial alternatives requires an estimate of the amount of soil that each alternative must address. Most remedial alternatives evaluated in the DAA use a volume estimate for developing costs, but some alternatives are based on area (e.g., capping, landfarm/agricultural practices). This appendix explains estimation methods and summarizes volume and area estimates that were generated for Rocky Mountain Arsenal (RMA) soils exceedance sites. As discussed in Section 3.0, 111 exceedance sites have been identified as requiring consideration for remediation in the DAA. These sites were organized into 27 subgroups. Exceedance volumes and areas were estimated separately for each of the sites. The estimates for each site were summed into medium group or subgroup totals to allow sites with similar remediation characteristics to be evaluated together. The medium subgroups are classified into four categories based on the type of criteria that are exceeded. These categories are the Potential Unexploded Ordnance (UXO) Presence, Potential Agent Presence, Biota Exceedance, and Human Health Exceedance Categories. p52
