The Army told the Nuclear Regulatory Commission it could cost $3.2 billion to clean the area for unrestricted use. Waste that was left in place is now interred beneath largeengineered covers that prevent intrusion by humans or animals,and also preventfurther contamination of groundwater. To read the report, click here. The Act also provides that to the extent possible, parts of the Arsenal are to be managed as a Refuge in the interim. 1989The U.S. 1995-1996Following extensive community input, the Off-Post and On-Post Records of Decision (ROD) are signed. And the biggest bills have yet to be paid. Both those cases are pending in federal court. The U.S. Army has begun removing Building 130, which is located northeast of the Refuge Visitors Center. There are multiple paved, boardwalk, or gravel trail options with a variety of lengths and difficulty levels available. After the war, it became a bustling center of industrial. After the war, it became a bustling center of industrial activity -- a top-secret center that created a lot of dangerous waste. 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. There is no appropriate standard by the EPA, but the state of Colorado has a standard treatment protocol for this chemical. The Army and Shell operated Basin F, a hazardous waste surface impoundment for the storage and treatment of liquid and solid hazardous wastes, but the facility leaked wastes into the environment after waste disposal ended in 1981, the lawsuit says. Waste further down than 10 is left in place in the former areas where the basins, chemical sewers, manufacturing plants, disposal trenches once were. The magnitude 5.2 event caused widespread minor damage in the suburban areas of northeast Denver. 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. The second largest earthquake in the Denver series occurred on November 26, 1967. [3] One of the goals of the MMP was to enhance community assurance that the clean-up was effective, and it included air quality monitoring, cancer surveillance, and birth defects surveillance. Spills occurred in the central processing areas, storage areas, and out of chemical sewers that existed underground. These monitors tested the air for several decades during the cleanup and showed the cleanup was protective of public health. Rated magnitude 1.5, it was not strong enough to be felt by area residents. 1943From 1943 to 1946, the Rose Hill Prisoners of War Camp houses captured German soldiers at the RMA. CERCLA also gave the Federal government the authority to respond to the release of life-threatening hazardous materials.[2]. 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. 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. Provisions for a permanent water supply for off-post residents affected by arsenal groundwater contamination. (7 of 9), BENEFIT - Cleanup of the Rocky Mountain Arsenal has bolstered the economy of the greater Denver metro area and provides its neighbors with jobs, recreation, and a peaceful escape to nature. (6 of 9), TOURISM - Nearly 500,000 people annually visit the 15,000-acre Rocky Mountain Arsenal National Wildlife Refuge where they can see more than 330 species of animals including bison, deer, bald eagles and black-footed ferrets. Fish and Wildlife Service establishes a field office at the RMA to manage bald eagles and other wildlife. The brochure contains general information, license requirements, fee requirements, and a list of fish species. 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. Rocky Mountain Arsenal, among other post-military sites, was a top priority, establishing RMA as a superfund site. In 1985 the Army permanently sealed the disposal well in stages. No significant increase was observed in congenital anomalies during the clean-up period compared to pre-clean up, although there are no baseline data prior to initial contamination events because data was not yet being collected and the population was very different at that time. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal traces its beginnings to the Dec. 7, 1941, attack on Pearl Harbor, which brought the United States into World War II.. The site was operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992. Many residents reported it was the strongest earthquake they had ever experienced. The Army is still struggling with cleaning up Jefferson Proving Ground in southeastern Indiana, part of which becameBig Oaks National Wildlife Refuge.

Current Basin F liquid consists of very salty water that includes some metals, chlorides, wastewater and toxic organics. State health officials are asking the federal courts to intervene to stop the contamination on the north and northwest boundaries of the trenches. Colorado health officials contendthat Shells trenches and slurry walls have not prevented pesticides and other dangerous chemicals from leaching into the groundwater. U.S. The CDPHE issued the Army a notice of non-compliance, claiming its containment and treatment measures were not working. But forty years ago, a series of quakes rocked the Denver area -- quakes caused not by Mother Nature, but by Uncle Sam. Contaminated ground water was first discovered to have migrated off of the Arsenal in the mid-1950s when crop damage and affected livestock was noted on farms north of the Arsenal. Because of the Superfund site status and the dramatic cleanups, many residents in neighborhoods surrounding the RMA voiced concern about ongoing health risks of living within the close vicinity of the site. These field activities began in the fall of 1997 and significant portions of the cleanup have already been accomplished. This new publication offers highlights from the past year, along with news about upcoming projects scheduled for 2022. Two sites were retained by the Army: the South Plants location due to historical use[clarification needed], and the North Plant location, which is now a landfill containing the remains of various buildings used in the plants. text only version of the Rocky Mountain Arsenal Site Spotlight, Emerging Contaminants and Contaminants of Concern, Federal Agency Hazardous Waste Compliance Docket, Military Munitions and Unexploded Ordnance (UXO). Theoretically, if the Earth still exists in the year 3000, theyll still be monitoring groundwater at the arsenal, he said. Recent tests have confirmed that the contamination continues to this day, it says. The defendants must build a system to actively dewater Shells trenches to prevent the mixing of effluent with groundwater, the lawsuit says. The refuge is currently open from sunrise to sunset. Fish and Wildlife Service management, and they now protect black bears and black-footed ferrets, coral reefs and brushy steppes, rare birds and imperiled salmon. 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. The well remained unused for nearly 20 years. Annual Highlights from Rocky Mountain Arsenal, Rocky Mountain Arsenal has recently published its annual community report. The U.S. Army constructed the Arsenal in 1942 to develop chemical weapons as a deterrent against the Axis Powers. (1 of 9) SITE HISTORY - Rocky Mountain Arsenal was listed on the NPL in 1987. The Off-Post Record of Decision was finalized in December 1995 and its requirements consist of actions for off-site groundwater and soil. A .gov website belongs to an official government organization in the United States. A similar shock, magnitude 4.1, centered in the Denver area November 15. Rates of birth defects in the communities surrounding the arsenal were also monitored and found to be stable and no different than rates for all of Colorado. Further, in 1961, the Army constructed a 12,000-foot deep injection well for the disposal of wastes. Archives: Project Descriptions / Fact Sheets, Hosted by Defense Media Activity - WEB.mil. 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. The cleanup was completed in 2010 and five large parcels of land have been deleted from the NPL . The history of the Rocky Mountain Arsenal National Wildlife Refuge stretches back more than 60 years. 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. Fish and Wildlife Service to establish a field office at the RMA to help manage the abundant wildlife. The waste fluid chemistry is not known precisely. Following a final land transfer, the Refuge expands to 15,000 acres and becomes one of the largest urban national wildlife refuges in the United States. Due to the early completion of this program, the Army realized a savings of 300,000 dollars. [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. In summary, there is no current evidence of health effects. (9 of 9). From 1950 to 1952, the Army constructed the North Plants complex to manufacture the nerve agents VX and GB, (also called sarin). [12] Though the cleanup of the site was considered complete in 2010, soil and groundwater monitoring practices occur every five years to ensure the effects of the clean-up remain. When the Cold War ended in the 1980s, more surplus military lands were earmarked for refuges. State and federal officials say its safe, but skeptical activists filed a lawsuit saying the federal government didnt test the refuge carefully enough. In 1987, the RMA was placed on the National Priorities List (NPL) of Superfund sites. For testing purposes, the well was injected with approximately 568,000 gallons of city water prior to injecting any waste. Here's the history of the Arsenal quakes from the USGS site: It was 32 minutes after 4 a.m. on April 24 when the first shock of the Denver series was recorded at the Cecil H. Green Geophysical Observatory at Bergen Park, Colorado. Cancer incidence in the communities near the arsenal was also monitored and found to be varied across location, gender, race and time, and have been determined to not be related to past Arsenal exposure or cleanup activities. The Rocky Mountain Arsenal National Wildlife Refuge is 15,000 acres and features three lakes that are home to over 300 species of wildlife. 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. A more recent article in 2004 by Pimentel,[19] estimated the cost of removal pesticides from the groundwater and soil at the Rocky Mountain Arsenal by approximately $2 billion. Now a majority are voluntarily adopting them. Montbello is located to the south of the RMA, and Commerce City to the west. That rankles Tim Maloney, a senior policy director for the Hoosier Environmental Council. 1952Shell Chemical Co. purchases Julius Hyman and Company and continues to manufacture agricultural chemicals at the RMA until 1982.

After the attack on Pearl Harbor and the United States entered World War II, the U.S. Army began looking for land to create a chemical manufacturing center. First, the well casing was tested to evaluate its integrity. After 42 years of chemical manufacturing, in 1984, the United States Army began to inspect the level of contamination at Rocky Mountain Arsenal (RMA). During removal of contaminated soil and construction of the remedy containment structures, air monitoring was conducted at multiple sites in the Arsenals interior and fence line, and several sites in the surrounding communities. This led the State of Colorado to take legal action over who has legal authority over RMA remediation efforts, payment of natural resource damages (NRDs), and reimbursement of costs expended for cleanup activities (response costs). The primary contaminants include organochloride pesticides, organophosphate pesticides, carbamate insecticides, organic solvents and feedstock chemicals used as raw products or intermediates in the manufacturing process (e.g., chlorinated benzenes), heavy metals, chemical warfare material and their related breakdown products and biological warfare agent such as TX. Soldiers test-fired millions of artillery rounds at the proving ground, some made of depleted uranium. Contaminants included solvents, metals, pesticides, and miscellaneous manufacturing-related chemicals. Organochlorine pesticides, heavy metals, agent degradation products and manufacturing by-products, and chlorinated and aromatic solvents are getting into groundwater in unsafe levels, it says. The Colorado School of Mines rated this shock magnitude 5.0. Located just north of Denver, in Commerce City and close to the Stapleton Airport, the U.S. Army purchased 20,000 acres (81km2). During November 1967, the Denver region was shaken by five moderate earthquakes. However, when the Basin F liquids were actually introduced, the process required more time than anticipated to complete because of the impermeability of the rock. The military, the U.S. Department of Energy and private companies have spent more than $57 billion to clean up the six heavily polluted sites, according to figures gathered by The Associated Press from military and civil agencies. [13], As part of the clean up of the RMA, much of the soil, up to 10 feet below the surface was removed from the site. All waste that was left in place is now interred beneath large-area engineered covers that prevent any intrusion into the waste that remains below. In this study, baseline birth defects were estimated from the time period 19891997, which was the point at which the clean-up began, and inclusion criteria included mother's address at the time of birth being within the geographical study area. 1962Treated liquid waste is injected into a deep well located more than 12,000 feet below the ground surface. An official website of the United States government, Rocky Mountain Arsenal has recently published its annual community report. The location was ideal, not only because of the proximity to the airport, but because of the geographic features of the site, it was less likely to be attacked. A civic center, high school, soccer complexand public open space are also located here. Fish and Wildlife Service that at least 20,000 ducks died in a 10-year span during the 1970s. Many homeowners reported wall, ceiling, floor, patio, sidewalk, and foundation cracks. Solid and liquid chemical hazardous wastes were disposed of in trenches, burn pits and pooled in open basins covering wide areas. Fish and Wildlife Service andShell Oil Company. I think theres a case to be made that just leaving it in place really maintains an unacceptable risk of contamination spreading from the site, he said. Additional cement barriers were placed inside the casing across zones that could access water-bearing formations (aquifers). 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. Exchanging animals among smaller herds. They would be worse if they were surrounded by a fence and left off-limits for decades and decades, said David Havlick, a professor at the University of Colorado at Colorado Springs who studies military-to-wildlife conversions. All manufacturing activities ended in 1982. Since 1985, the mission at RMA has been the remediation of the site. 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. But parts of the refuge remain off-limits, including specially designed landfills where the Army disposed of contaminated soil. The contaminated groundwater that still exists in and around RMA continues to be actively monitored. 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. 1969Powered by rocket fuel propellant manufactured at the RMA, Apollo 11 lands on the moon. In addition, there were actions completed by Future Farmers of America (FFA) between 1991 and 1993 that cost approximately $151.2 million. 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. Boulder sustained minor damage to walls and acoustical tile ceilings on April 27, 1967, as result of a magnitude 4.4 earthquake. Additionally, studies performed at Colorado State University found no increased risk of Arsenic, Mercury, or neurotoxicity in communities within 15 miles of the RMA.[16][17]. Today, the Rocky Mountain Arsenal, once some of the most contaminated land in the country, is a cleaned-up nature center. This new publication offers highlights from the past year, along with news about upcoming projects scheduled for 2022. Beginning in 1942, the arsenal was the main site at which the Chemical Corps manufactured chemical weapons such as mustard gas, nerve gas, and phosgene.The Army eventually leased part of the 27 mi 2 (70 km 2) plot of . During the cleanup of the RMA, concern for air pollution from the hazardous materials was raised. 24,590 were here. As production declined at wars end, the U.S. Army leased some of the facilities to private companies, one of which Shell Oil Co. purchased, for the production of agricultural chemicals.

A 14-year, $2-billion remediation effort begun in 1996 will turn most of the arsenal into a national wildlife refuge. A lateral was built off the High Line Canal to supply water to the Arsenal. An astonishing array of animals and habitats flourished onsix obsolete weapons complexes mostly for nuclear or chemical arms because the sites banned the public and other intrusions for decades. Lake Skipper (s): This public availability will be implemented while simultaneously supporting the remediation effort and the USFWS activities. CERCLA was a tax imposed on chemical and petroleum industries. Beginning in 1942, the Army used the 27-square-mile arsenal at 5650 Gateway Road in Commerce City for the manufacture and disposal of chemical warfare agents, and chemical and incendiary munitions. The waste from the pre-treatment plant was generally a solution containing 13,000 parts per million sodium chloride (salt), with a pH ranging from 3.5 to 11.5. Make a one-time donation today for as little as $1. This legacy, they say, requires restrictions on where visitors can go and obligates the government to monitor the sites for perhaps centuries. The U.S. Army and Shell conducted the $2.1 billion environmental cleanup of the site in collaboration with the Environmental Protection Agency, Colorado Department of Public Health and Environment and Tri-County Health Department. A local shock awakened a few persons in Commerce City November 25. They have been left in place to excavate, so they have been left in place. This resulted in subsequent earthquakes in Denver area. Houses creaked and objects rattled during this magnitude 2.1 earthquake. Its not because the Department of Defense has some ecological ethic, said Havlick, author of a book about conversions, Bombs Away: Militarization, Conservation, and Ecological Restoration.. Extremely loud, explosivelike earth noises were heard. 4300 Cherry Creek Drive South Denver, CO 80246, Colorado Health Information Data Set (CoHID), Office of Public Health Practice, Planning, and Local Partnerships (OPHP), Air Quality - Monitoring, Modeling and Data. In 2009, the state of Colorado, Shell Oil Co., and the United States Army settled a lawsuit pertaining to damages to the states natural resources from past activities at the Rocky Mountain Arsenal that caused extensive contamination of soil and water at the site. Only one, on July 15, caused minor damage at Commerce City. Slighter rumblings (below magnitude 3.0) occurred throughout the remainder of 1966, and through the first week of April 1967. Parts of a C-shaped buffer zone around the perimeter are open to visitors asHanford Reach National Monument. Most of the land areas now belong to the U.S. There are many studies that try to estimate the total costs due to contamination of pesticides in U.S. as well as in other countries; however, indirect costs are difficult to estimate, but likely several times than total direct environmental and social costs. The Army was dumping dangerous chemicals into a deep injection well out at the Rocky Mountain Arsenal. More than 600 chemicals have been used or manufactured at the arsenal, including: Diisopropyl methylphosphonate (DIMP), a chemical unique to the Army's manufacture of nerve gas. The Army discontinued use of the well in Feb. 1966 because of the possibility that the fluid injection was triggering earthquakes in the area. Critics sayRocky Mountain Arsenalin Colorado illustrates the shortcomings of a cleanup designed to be good enough for a refuge but not for human habitation. Its latest plan calls for waiting 20 years in hopes that better, less expensive technology emerges or the unexploded shells degrade to a safe level. Reunion is located on the north border of RMA. Known today as an urban national wildlife refuge, the Rocky Mountain Arsenal is one of the most studied environmental cleanup sites in the country.
