report presents the results of the laboratory studies on inorganic contaminant removal from RMA groundwater conducted at WES with the literature review and treatability work conducted at RMA included in appendices as noted. Leading the design and stewardship of land and communities the Rocky Mountain Arsenal National Wildlife Refuge Comprehensive Management Plan served a visionary purpose in the conversion of a 17,000-acre Superfund site into one of our nation's largest urban wildlife refuges. Study of inorganic contaminant removal from Rocky Mountain Arsenal (RMA) groundwater, Bench- and pilot-scale thermal desorption treatability studies on pesticide-contaminated soils from Rocky Mountain Arsenal, Alternative carbon source study for the Department of the Army, Rocky Mountain Arsenal, Ecological risk characterization based on exposure to contaminants through the Rocky Mountain Arsenal aquatic food chains, Onsite landfill feasibility evaluations performed at Rocky Mountain Arsenal. âLocation because ofdistance from coasts; not likely to be attacked. FROM CHEMICAL WEAPONS TO WILDLIFE REFUGE. samples of spent granular activated carbon was submitted to RMA on January 30, 1981. Delays due to materials-handling problems and permit issues have delayed the start of the pilot-scale DFTD testing. The facility was built in 1942, in response to the outbreak of World War II in Europe. In 1942, the U.S. Army established Rocky Mountain Arsenal (the Arsenal) on 20,000 acres of land outside of Denver purchased from homesteaders. Rocky Mountain Arsenal Background â¢US Army purchased the Arsenal lands in 1942. âManufacture chemical warfare agents and incendiary munitions for World War II. An Interim Report summarizing the results of preliminary carbon source screening efforts, adsorption isotherm testing and results of laboratory reactivation of four, This paper describes ecological risk characterization methods and results for characterizing potential risk from exposure to bioaccumulative contaminants of concern (aldrin, dieldrin, endrin, DDT, DDE, and mercury) through the lake food chains at Rocky Mountain Arsenal (RMA). Following the war, and through the early 1980s, the Army continued to use these facilities. Under orders to cease and desist off-site discharge of contaminated groundwater, the U.S. Army has constructed the north boundary barrier system (NBBS) to â¦ Rocky Mountain Arsenal Community Involvement Plan January 2008 3-2 â¢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. The EPA has classified PFCs as among a group of âemerging contaminantsâ that are being looked at more broadly and warrant further study. The Colorado divisionâs Hazardous Supplies and Waste Administration Division filed the lawsuit Monday in U.S. District Court docket in Denver to pressure the [â¦] Most badgers at Rocky Mountain Arsenal appear to be unaffected by dieldrin, one of the main chemical contaminants remaining in the soil at the military base. State well being officers are asking the federal courts to intervene to cease the contamination on the north and northwest boundaries of the trenches. Rocky Mountain Arsenal (RMA)has been used as a facility for numerous military and non-military activities which have resulted in the introduction of both organic and inorganic contaminants into the groundwater. Additional testing revealed that the containment subject is an ongoing drawback, the lawsuit says. Well monitoring at (Rocky Mountain Arsenal) has indicated that certain inorganic contaminants have migrated into the groundwater in concentrations above mandatory or suggested standards. been sampled annually to monitor their status on contamination. 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. 207P, 540250* - Environment, Terrestrial- Site Resource & Use Studies- (1990-). Litigation Technical Support and Services, Rocky Mountain Arsenal: Final Phase I Contamination Assessment Report, Sites 1â13 and 2â18, South Plants Manufacturing Complex, Shell Chemical Company Spill Sites, Version 3.1. The history of the Rocky Mountain Arsenal National Wildlife Refuge stretches back more than 60 years. The CDPHE issued the Military a discover of non-compliance, claiming its containment and therapy measures weren’t working. A 14-year, $2-billion remediation effort begun in 1996 will turn most of the arsenal into a national wildlife refuge. The information obtained from the field scale system will be presented in a separate report at a later date. It cited seven violations. Rocky Mountain Arsenal continues to leak contaminants into groundwater, Colorado health department lawsuit says Contaminants include â¦ The former chemical weapons plant is now a wildlife arsenal. 2 â South Plants. The available data will be presented March 9, 1995, at the Seventh Annual Gulf Coast Environmental Conference in Houston, Texas. The Rocky Flats National Wildlife Refuge opened to the public on September 15, 2018. One monitoring project has demonstrated incremental improvements over time, and specifically measured 640 parts per billion (ppb)in 1987 and 55 ppb in 1989, while a different off-post monitoring well measured 138 ppb in 1985, 105 ppb in 1987, 14 ppb in 1988, and 6.7 ppb in 1989. Many projects have attempted to clean contaminated groundwater at the Arsenal. This paper intends to compare existing data from a bench-scale IHTD treatability study using equipment operated in the batch mode to new data from a pilot-scale DFTD operated in a parallel-flow continuous mode.
