During November 1967, the Denver region was shaken by five moderate earthquakes. To learn more and view artifacts from each period, visit the Refuge Visitor Center. The brochure contains general information, license requirements, fee requirements, and a list of fish species. From a tiny Pacific island to a leafy Indiana forest, a handful of sites where the United States manufactured and tested some of the most lethal weapons known to humankind are now peaceful havens for wildlife. These field activities began in the fall of 1997 and significant portions of the cleanup have already been accomplished. (La hoja de datos tambin est disponible en espaol aqu.). Reunion is located on the north border of RMA. Washington state officials are worried that the Trump administration wants to reclassify millions of gallons of wastewater at Hanford from high-level radioactive to low-level, which could reduce cleanup standards and cut costs. It cited seven violations. Share sensitive information only on official, secure websites. The deep injection well was closed in 1985 and Basin F was closed in 1988 [10] Legislators quickly moved from beneath chandeliers in the Denver Capitol Building, fearing they might fall. This soil is contained in hazardous waste landfills. How? So theres a huge downside to converting it into a wildlife refuge, because it allows residual contamination to remain in place, said Jeff Edson, a former Colorado state health official who worked on the cleanup. Keeping our congressional leaders . By year end, the United States has out-produced the Axis Powers by 150 percent. Fish and Wildlife Service is responsible for managing the Arsenals wildlife and habitat. Throughout the decades of cleanup, the air monitors revealed there was no safety hazard to public health as no arsenal chemicals had been released into the air. The land is sold to Commerce City for commercial and retail development. 2007The EPA honors the RMA with its national Land Revitalization Award. Many of the surrounding neighborhoods have been provided with potable tap water from other areas of Adams county because of the potential effects of contaminated groundwater from wells. When the cleanup was completed, it was clear that no Arsenal chemicals had been released into the air that exceeded the health-protective levels established for the site since the environmental cleanup began in October 1997. Since there is no further use for the building, the Army will remove it as part of a larger effort to reduce the Armys footprint at RMA. A volume of approximately 52,500 acre-feet (65 million cubic metres) of the alluvial aquifer is not usable for human consumption. The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado. Slighter rumblings (below magnitude 3.0) occurred throughout the remainder of 1966, and through the first week of April 1967. The contaminated groundwater that still exists in and around RMA continues to be actively monitored. During 1968, ten slight shocks were felt in Colorado. Today, the Refuge encompasses more than 15,000 acres of restored shortgrass prairie and provides habitat to more 300 species of wildlife, including American bison, bald eagles, mule and white-tailed deer, burrowing owls and black-footed ferrets. For example, DIMP (diisopropyl methyl phosphonate) was one of the main contaminants in the area. This was further exacerbated when the U.S. Army discovered an endangered species, the bald eagle. Denver's independent source of [4], 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. Fish and Wildlife's Rocky Mountain Arsenal website. From 1943 to 1956, the US Army and Shell discharged wastes into the unlined basins resulting in the contamination of the South Platte River outside the Arsenal. Boulder sustained minor damage to walls and acoustical tile ceilings on April 27, 1967, as result of a magnitude 4.4 earthquake. Current Basin F liquid consists of very salty water that includes some metals, chlorides, wastewater and toxic organics. [8][9] The well remained unused until 1985 when the Army permanently sealed the disposal well. [3] After the bald eagles were captured, tested, and found to be healthy, the National Wildlife Federation worked with policymakers to transition RMA to a wildlife refuge. It was an inexpensive way to expand the national refuge system, especially in urban areas with scarce open space, said Mark Madison, the Fish and Wildlife Services historian. Is there a risk of cancer related to Rocky Flats contamination? They awakened many residents, but were not widely felt. The cleanup of the refuge's 15,000 acres was completed in 2010. Rocky Flats National Wildlife Refuge, a former nuclear weapons plant northwest of Denver, opened to hikers and cyclists last September, but some activists question whether its safe. The U.S. Despite the complicated and expensive cleanups, significant contamination has been left behind, some experts say. Depleted uranium fragments are scattered on the firing range among 1.5 million rounds of unexploded shells, which makes cleanup dangerous and expensive. Today, only the foundation of a watch post from Rose Hill is visible, and then only when pointed. At Commerce City merchandise fell in several supermarkets and walls cracked in larger buildings. In the mid-1980s, wildlife, including endangered species, moved into the space and the land became a protected park. Starting in 1942, the U.S. Army used the 27-mile site for the manufacture, assembly, and disposal . 2010All surface environmental cleanup work concludes. The Energy Department told the state it has no current plans to change the classification. Subsequently, through the 1970s until 1985, RMA was used as a demilitarization site to destroy munitions and chemically related items. 2011In cooperation with federal, state and local regulatory agencies, the U.S. Army permanently maintains 1,000 acres at the site containing the landfills, waste consolidation areas and groundwater treatment facilities. There are multiple paved, boardwalk, or gravel trail options with a variety of lengths and difficulty levels available. The Army and Shell Oil Co. began conducting detailed site investigations in the 1970s to define the extent of contamination. The history of the Rocky Mountain Arsenal National Wildlife Refuge stretches back more than 60 years. In addition to the containment structures, the agreed-upon remedy directs that the entire area is subject to restrictions on land use in perpetuity, including residential development, agricultural use, any potable use of the groundwater, and any consumption of fish or game from the Arsenal. Additionally, some of this land was used for a prisoner of war camp (for Germancombatants) and later transferred to the city of Denver as Stapleton Airport expanded.

CERCLA was a tax imposed on chemical and petroleum industries. 1942The U.S. Army establishes the Rocky Mountain Arsenal to produce chemical weapons as a war-time deterrent. 1943From 1943 to 1946, the Rose Hill Prisoners of War Camp houses captured German soldiers at the RMA. [14] The following data were derived from the Rocky Mountain Arsenal Medical Monitoring Program Surveillance for Birth Defects Compendium prepared by Colorado Department of Public Health and Environment and published in February 2010. local news and culture, Patricia Calhoun In September of that year, the Army began removing fluid from the Arsenal well at a very slow rate, in hope that earthquake activity would lessen. RMA contained a deep injection well that was constructed in 1961. CERCLA also gave the Federal government the authority to respond to the release of life-threatening hazardous materials.[2]. The Army and Shell took remedial actions to prevent the contamination that includes the installation of the groundwater barrier system which treated approximately 1 billion gallons of water every year. The Denver series was forgotten, however temporarily, in October 1966, when a southeast Colorado tremor rocked a 15,000 square-mile area of that State and bordering New Mexico. State and federal officials say its safe, but skeptical activists filed a lawsuit saying the federal government didnt test the refuge carefully enough. Photo source:CBS Denver Fish and Wildlife Service. Damage on a lesser scale occurred throughout the area. The settlement amount totaled $27.4 millionand is to be used for natural resources restoration projects in the South Platte River area. Contaminants included solvents, metals, pesticides, and miscellaneous manufacturing-related chemicals.

In addition, there were actions completed by Future Farmers of America (FFA) between 1991 and 1993 that cost approximately $151.2 million. In the early 1980s the site was selected as a Superfund site and the cleanup process began. 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. According to National Resource Damage Assessment, although the contamination has been reduced by the treatment efforts, the water in and around the arsenal may never be fully clean. Further, there have been damages to the rural areas due to contamination resulting in livestock losses, and crop losses. Treatment plants remove contaminants from groundwater to keep them out of domestic wells. Both those cases are pending in federal court. For questions about Refuge programs and conservation efforts, please contact the U.S. The defendants must build a system to actively dewater Shells trenches to prevent the mixing of effluent with groundwater, the lawsuit says. Another group asked the courts to release documents from a 27-year-old criminal investigation into the weapons plant, hoping they will show whether the government tracked down and cleaned up all the contamination. Air monitoring surveillance continued until the end of July 2009. August 24, 2011 The Rocky Mountain Arsenal National Wildlife Refuge has been transformed from a 17,000+ acre facility used for weapons and chemical manufacturing into a beautiful nature sanctuary. Statistically significant findings (p<0.01) of this study included demographic differences in the mothers as follows: median age 24, compared to 27 years of age in Colorado as a whole, higher percent of mothers who were white/Hispanic and black, mean education level of 11.8 years compared to 13.1 years in Colorado as a whole, fewer mothers who were married, and fewer prenatal visits on average. The cleanup was completed in 2010 and five large parcels of land have been deleted from the NPL, creating opportunities for reuse development and expansion of the Refuge. 1962Treated liquid waste is injected into a deep well located more than 12,000 feet below the ground surface. 1989The U.S. Army, EPA and Shell sign the Federal Facilities Agreement, which provides a framework for decision-making and for completing 14 Interim Response Actions (IRAs) while final cleanup plans are developed. EPA and the State concurred with the approach. They have been left in place to excavate, so they have been left in place. The perfect trail for those who like to enjoy nature from the comfort of their air-conditioned vehicle with a latte in hand. One of the lessees, Julius Hyman and Company, manufactures agricultural chemicals at the site. Rocky Mountain Arsenal National Wildlife Refuge was established in 2004, in part, to protect our national symbol, the bald eagle. In 1975, Colorado Department of Public Health and Environment ordered the Army and Shell to stop the non-permitted discharge of contaminants, to control the contaminated groundwater leaving the site, and to implement a monitoring plan. Soldiers test-fired millions of artillery rounds at the proving ground, some made of depleted uranium. The site was placed on the National Priorities List (NPL), a list of the most contaminated areas in the United States. During the development of the remedy for the Arsenals contamination, there was a lot of public concern that the cleanup itself might pose a risk to the surrounding residents. [11], The NRDA found several injuries to wildlife. The On-Post Record of Decision was signed in June 1996 and describes the cleanup plan for soils, groundwater and structures within the approximately 27-square-mile on-post Operable Unit. 1943RMA employees work around the clock to manufacture mustard gas, Lewisite, chlorine gas and incendiary weapons. Exchanging animals among smaller herds. The Arsenal also played a role in Americas space exploration by manufacturing the rocket fuel used to power the Apollo 11 flights. State health officials are asking the federal courts to intervene to stop the contamination on the north and northwest boundaries of the trenches. The end result was approximately 165 million gallons of Basin F liquid waste being injected into the well during the period from 1962 through 1966. The injected fluids had very little potential for reaching the surface or usable groundwater supply since the injection point had 11,900 feet (3630 m) of rock above it and was sealed at the opening. The U.S government acquired the Arsenal land in 1942 to manufacture chemical warfare agents, including mustard gas and incendiary munitions, for use in World War II. Critics say Rocky Mountain Arsenal in Colorado illustrates the shortcomings of a cleanup designed to be good enough for a refuge but not for human habitation. An official website of the United States government. Birth defects included in the analysis were: "total congenital anomalies, major congenital anomalies, heart defects, muscle and skeletal defects, and kidney and bladder defects," and these categories were inconsistent in reporting accuracy. Many residents reported it was the strongest earthquake they had ever experienced. Fish and Wildlife Service at 303.289.0930, or visit the Refuge online. Finally, the Act provides for the transfer of some Arsenal land for road expansion around the perimeter of the Arsenal and 915 acres (3.70km2) to be sold for development and annexation by Commerce City. In 1987, the RMA was placed on the National Priorities List (NPL) of Superfund sites. selected for the Rocky Mountain Arsenal includes the removal of contaminated soil down to 10 over much of the contaminated area, and that contaminated overburden is contained in two hazardous waste landfills that remain on the site. The Army discontinued use of the well in February 1966 because the fluid injection triggered a series of earthquakes in the area. But the cost of the conversions is staggering, and some critics say the sites have not been scrubbed well enough of pollutants to make them safe for humans. EPA and the State concurred with the approach. To read the report, click here. [8] It was drilled to a depth of 12,045 feet (3671 m). The building was known as the Environmental Analytical Laboratory, and was used to analyze soil, water, and air samples collected during the environmental clean-up of RMA. The final step was adding Bentonite, a heavy clay mud that later solidified, to close the rest of the hole up to the ground surface. Fish and Wildlife Service inventoried more than 330 species of wildlife that inhabit the Arsenal including deer, coyotes, white pelicans and owls. 1952Shell Chemical Co. purchases Julius Hyman and Company and continues to manufacture agricultural chemicals at the RMA until 1982. Eating fish and game from the refuge is forbidden. CDPHE is asking the federal court to compel the Army to install or modify the existing treatment system to effectively prevent pollutants from contaminating groundwater, the lawsuit says. independent local journalism in Denver.
