Health assessment for Rocky Mountain Arsenal, Commerce City, Adams County, Colorado, Region 8. CERCLIS No. CO5210020769. Preliminary report
The Rocky Mountain Arsenal (RMA) National Priorities List site is located in Adams County, Colorado. The RMA has been owned by the U.S. Army since 1942 and comprises over 17,000 acres (approximately 27 square miles). RMA has been used since 1942 by both government and industry to manufacture, test, package, and dispose of various chemical products, chemical-warfare agents, and munitions including, but not limited to, rocket fuels, herbicides, pesticides, nerve gases, mustards, and incendiary munitions. Surface or near-surface soils have been found to contain elevated levels of arsenic (up to 1,100 ppm) and mercury (up to 65 ppm). Sediment samples from on-post lakes and drainage areas are contaminated with metals and pesticide residuals. On-post ground water is contaminated in both the alluvial and bedrock aquifers. Based on information reviewed, it is apparent that previous on-site hazardous waste disposal practices and releases have led to contamination of alluvial aquifers and, to a limited extent, one or more of the bedrock aquifers.
