Approximate Location

B-1

Powder and ammunition burn area used in 1954 for burning powder and incendiary materials. Areas of stressed vegetation were observed in the field.

North pasture

B-2

Small arms ammunition burning area used in 1954. Two trenches were observed in historical aerial photos and confirmed during field survey. 57mm, 128A1 ammunition canisters and fire brick/ammunition piles were also observed.

North pasture to the east of B-1

B-3

Landfill area used primarily for garbage disposal and burning trash that was filled in 1990-1991. The garbage disposal was field verified.

Inner cantonment area northeast of main compound, southeast of well 16

B-4

Classified burn area used to burn classified documents and trash. This area makes up part of a large area of no vegetation surrounding the oxidation pond. The field survey revealed additional SWMUs in the immediate vicinity.

Inner cantonment area northeast of the main compound due south of B-3

B-19

Miscellaneous solid waste, metal and weapons identified on CSSA's original list. This area was later located in the field and identified as a potential borrow area of soils. No indications of waste management activities were identified.

West of oxidation pond

B-28

Area where trenches of molten metal, small arms ammunition, and metal ammunition parts were disposed of.

West of the oxidation pond and B-19

O-1

An oxidation pond constructed in 1975, however, a relatively small cleared area can be seen in the 1973 aerial photo. The pond was lined with a vinyl plastic with a life expectancy of 10 years. Waste liquids and sludges were tank-collected from the bluing operation, trucked to the evaporation pond and pumped out. A sample of the top liquid and sludge were taken to Brooks AFB on 20 April 1984 for evaluation at the request of TDH and tested for metals. In 1985, the RRAD prepared a recommended procedure for closure of the evaporation pond. The evaporation pond was filled in with soil in the fall of 1985.
