- Section about Background
History of site use
Drivers discarded squanders created at the Depot in trenches, tidal ponds, landfills or other holding vessels from the 1940s through the late 1970s. A large portion of the waste originated from the SIA. In 1989, EPA recorded the SIA on the NPL. A 1990 Federal Facilities Agreement incorporated the Army's RCRA and Superfund program necessities for the whole Depot.

The 15,200-section of land establishment has a base in the Calhoun County, Alabama. It is 10 miles west of the renowned Anniston. It is worth noting that the northern side of this given Depot stems out as the Pelham Range bit of the Fort Mcclellan Military Reservation. The focal and northern allotments of the Depot compass in excess of 13,000 sections of land and serve as an ammo stockpiling range. The renowned southern side of the same Depot stems out as the Southeastern Industrial Area,which is a 600-section of land dynamic modern operations territory. The SIA holds more than 50 structures and a vehicle test track.
Other info: Climate, population
Roughly 3,400 individuals work at the Depot. Fences and watchmen control access. Area use encompassing the establishment is generally private. Surface water inside the SIA channels into Dry Creek, which streams into Choccolocco Creek, a tributary of the Coosa River. Coldwater Spring is spotted by Dry Creek, something like one mile south of the Depot limit. The spring is the fundamental wellspring of drinking water for Calhoun County. Anniston Water Works and Sewer Board right now supplies water to the Depot by pipeline (http://www.epa.gov/region4/superfund/sites/fedfacs/anarmydptal.html).
- Results of remedial investigation
ID chemicals, concentrationSite examinations brought forth the fact that pollution in ground water and soils could conceivably affect individuals in the region. Contaminants of concern incorporate antimony, chromium, lead, thallium and trichloroethylene.Locations/ extension of contaminationTo address potential dangers connected with the contamination calls, the Army has put area use controls set up that disallow the establishment of drinking water wells in the zone and avoid presentation to polluted soils. The Army likewise screens private ground water wells included in a private well observing system, and takes suitable steps in the event that contaminant levels are above elected drinking water quality measures.·HRS As a major aspect of a progressing SIA ground water examination, the Army has additionally finished a private well stock to place well holders whose wells supply an essential drinking water source. A private well beside the SIA used to supply a business Catfish Lake had unstable natural compound (VOC) sullying above elected drinking water gauges. The Army bought the catfish lake property in 2007. It is worth noting that The Agency for Toxic Substances and also Disease Registry went on to issue a study in line with the fact that individuals who devoured fish from the previous lake were unrealistic to encounter hurtful wellbeing impacts.

Risk assessment - contaminates / media most concern
The Depot's 2010 Five-Year Review assessed the cleanup methodologies utilized for OU-1, OU-2 and OU-3. The survey found that the cleanup approach for OU-2 and OU-3 keeps on securing individuals and the earth from remaining site tainting. The audit found that the cleanup approach for OU-1 was not effectively treating OU-1ground water pollution. Abnormal amounts of ground water pollution stay underneath the given Depot and also any low levels of the ground water sullying proceed with spread past the Depot limit. While ground water medication proceeds, the Army is currently assessing diverse ground water cleanup alternatives to distinguish a more successful elective approach (http://www.epa.gov/region4/superfund/sites/fedfacs/anarmydptal.html).
Remediation approaches considered
Throughout the years, the Army has launched RCRA and Superfund-related movements that have tended to tainting and transfer issues at the Depot. These activities have included:
- treating ground water pollution
- removing and discarding defiled soil
- treating polluted soil on location
- emergency reaction making arrangements for off-site ground water defilement.
The Army keeps on capturing and treating defiled ground water by embracing an updated on location ground water block attempt framework and an air-stripping framework at the Krebs Water Treatment Plant. The Army is likewise tending to sullied cracked bedrock. The Army likewise plans to utilize specific advances to treat zones where it has recognized wellsprings of thick non- aqueous stage fluid.
Other info
In 2000, the Army worked with the nearby civil water supply to introduce five air-stripping towers. The Army paid for the development of the towers and the city water supplier pays for the towers' operation. Drivers utilize the towers to uproot Vocs in ground water. Plant drivers now treat all water in Coldwater Spring before supplying water to the general population. Treated water at the plant does not hold unsafe levels of Vocs.
A multi-office team, made up of agents from the U.s. Armed force Corps of Engineers, the US Fish and also Wildlife Service, ADEM, EPA and the State of Alabama's Fish and Wildlife Service, performs studies identified with ground water danger levels at the Depot as a component of exertions to ensure nearby natural life. The team is attempting to ensure the Pygmy Sculpin, a fish local to Alabama that just lives in the Coldwater Spring region. The Army and EPA will fuse the team studies into a future cleanup plan.
- Section about ROD:
Initial ROD
EPA and ADEM. The FFA helps verify that the society completely research ecological effects connected with over a wide span of time exercises at the establishment and embrace and complete proper cleanup activities. EPA has worked with the society and its state and elected accomplices to create a long haul cleanup plan for the Depot, reflecting the Agency's dedication to protected, sound groups and protection of the environment. The involvement of the community members and outreach to public stem put as core towards the EPA project exercises.
Subsequent ROD’s
EPA has directed a reach of community inclusion exercises at the Depot to request societal info and to verify people in general domains of educated about exercises all around the cleanup process. Outreach exercises have included meetings among people and the general public outreach. The Depot additionally has a Restoration Advisory Board (RAB) made out of members of the group and delegates from the Depot and orgs. The RAB serves as a major forum for members to examine and give enter on natural defilement and reclamation exercises.
- Section about Current status include these information:
The renowned Anniston Army Depot (the Depot) stems as a dynamic United States armed force establishment. The establishment gives weapons stockpiling and renovation, testing and decommissioning of battle vehicles and different sorts of arms. Previously, operations at the Depot created robust and fluid squanders that sullied soil and ground water. EPA put an allotment of the Depot on the National Priorities List (NPL) in 1989. In 1990, EPA and the Army consented to address the whole Depot that is deemed to be under the Superfund and also Resource Conservation and Recovery Act (RCRA) programs. It is worth noting that the Army, the EPA and also the Alabama Department of Environmental Management (ADEM) have investigated site conditions and made moves to clean up the Depot so as to ensure individuals and nature's domain from defilement. By cleaning up and observing the Depot's dirt and ground water, authorizing area utilization controls, and also the calls for undertaking Five-Year Reviews, ADEM, the renowned Army, and EPA keep on ensuring individuals and nature's turf from pollution.
