HWAAP-B31
BUILDING 101-65 CATCHMENT PIT
SITE DESCRIPTION
HWAAP-B31 is an inactive unlined surface impoundment pit located south of Building 101-65 and measures 70 by 32 by 5 feet. The impoundment is heavily  eroded and partially filled with windblown sand. A discharge pipe enters the pit from the northeast corner. Small piles of dredged soils surround the impoundment. This impoundment operated from 1940 to the early 1970's and received large amounts of waste water containing TNT and RDX. Remedial Investigation work in 1994 included surface soil and hand auger sampling, and cone penetrometer soundings. Two surface soil samples, two hand auger samples and three cone penetrometer soil samples were collected and analyzed for explosives and metals. Low concentrations of explosives and metals were detected in the soil. The site was reassessed in 1999 with improved sampling and analytical techniques. No further action is required.
PROPOSED PLAN
A Closure Decision Document was approved by the NDEP in April 2000.
