Installation Restoration Program. Phase II - Confirmation/Quantification Stage 1 for Maxwell Air Force Base, Alabama

A Phase II, Stage 1 survey was conducted at Maxwell Air Force Base MAFB, Ala., to confirm the existence of potential contaminants at former disposal and storage sites identified by a Phase I record search. Ten sites were investigated including six landfill or disposal areas, two fire protection training areas, a drum storage area, and surface water drainage areas. Geophysical surveys were conducted at four disposal areas, and 20 ground water monitor wells were installed. Surface waters, ground waters, and sediments were sampled and analyzed for various screening parameters including total organic carbon, total organic halogens, phenols, oil and grease, pH, specific conductance, and total dissolved solids. The samples were also analyzed for specific parameters including cyanide, cadmium, chromium, copper, zinc, lead, selenium, silver, barium, mercury, arsenic, sulfate, nitrate, iron, endrin, lindane, methoxychlor, toxaphene, 2,4-dichlorophenoxyacetic acid, and 2,4,5-trichlorophenoxyacetic acid. Results of the analysis indicate low-level contamination at several study sites. Additional testing is recommended to identify and quantify halogenated organic species and to further evaluate the extent of contamination of the shallow aquifer.
