One of the primary missions of the Anniston Army Depot ANAD is the repair of combat vehicles. Industrial processes which are utilized in the accomplishment of this mission led to the production of a large number of waste chemicals, mainly degreasing, paint stripping and metals processing sludges. Many of these waste chemicals are classified as hazardous under both Federal and State of Alabama hazardous waste regulations. The potential for localized groundwater contamination led to the decision to exhume, remove and dispose of the contaminated material in the seven disposal trenches. As part of this contract, the hazardous sludges in the old lagoon sludge pile were to be removed, although groundwater contamination was not associated with this site. Through the use of ground penetrating radar GPR, magnetometry, metal detection and electromagnetics, the exact boundaries of the chemical sludge disposal trenches were determined. A total of 62,119 tons of contaminated material and soils from the chemical sludge disposal trenches, old lagoon sludge pile and chemical sump at Building 130 were exhumed, transported and disposed of during the project.
