In 1942, the U.S. Army established Rocky Mountain Arsenal (the Arsenal) on 20,000 acres of land outside of Denver purchased from homesteaders. Generalizable insights from the aquatic ecological risk characterization, Currently, the conceptual remedy identified for containment and isolation of the contaminated soil and structural debris at Rocky Mountain Arsenal (RMA) in Commerce City, Colorado, includes the construction of an onsite hazardous waste landfill and the installation of caps. Rocky Mountain Arsenal Community Involvement Plan January 2008 3-2 •Toxic Storage Yards:Soil contaminated from past spills or leaks from containers and/or munitions was excavated and taken to the HWL and the Basin A consolidation area. There is a well-documented history of disturbance and contamination from previous activities on this site. Colorado well being officers contend that Shell’s trenches and slurry partitions haven’t prevented pesticides and different harmful chemical substances from leaching into the groundwater. The equipment used in the DFTD treatability study is of large enough scale to provide good full-scale design parameters and operating conditions. From 1988 through 1992, numerous laboratory- and bench-scale indirect-heated thermal desorption (IHTD) treatability studies have been performed on various soil medium groups from the arsenal. To perform the evaluations, a multidisciplinary approach was implemented. Delays due to materials-handling problems and permit issues have delayed the start of the pilot-scale DFTD testing. Rocky Mountain Arsenal Background •US Army purchased the Arsenal lands in 1942. –Manufacture chemical warfare agents and incendiary munitions for World War II. been sampled annually to monitor their status on contamination. samples of spent granular activated carbon was submitted to RMA on January 30, 1981. The Arsenal's location was selected due to its relative distance from the coasts (and presumably not likely to be attacked); a sufficient labor force to work at the site; weather that was conducive to outdoor work; and the appropriate soil needed for the project.

The study will also provide valuable-emissions and materials-handling data. Specifically this program will determine if DFTD can achieve reductions in soil contamination below the RMA preliminary remediation goals (PRGs), define system operating conditions for achieving the PRGs, and determine the fate of arsenic and other hazardous metals at these operating conditions. Potential landfill sites were screened with Geographic Information System (GIS) analyses using site wide geologic, geochemical, wildlife habitat, and physiographic information. The location was both difficult to reach by enemy bombers and accessible by rail, important considerations for the chemical warfare agent and incendiary munitions production facility. State well being officers are asking the federal courts to intervene to cease the contamination on the north and northwest boundaries of the trenches.
