HWAAP-I13
BUILDING 10 DISCHARGE/LANDFILL
SITE DESCRIPTION
HWAAP-I13 is a former discharge pit where petroleum hydrocarbons and paint residue were reportedly disposed from a sheet metal shop. The period of operations of the pit is not known. The site is presently filled to grade. The chemicals of concern include petroleum hydrocarbons, solvents, metals and PCBs from cutting oil. Remedial Investigation in 1994 included 0.01 acres of ground penetrating radar on a 2 foot grid identifying the former pit boundaries. One cone penetrometer sounding was advanced to 60 feet to define the optimum depth for subsurface sampling. Five subsurface soil samples were collected from one boring to a maximum depth of 60 feet for metals, VOCs, PCBs. Low concentrations of VOCs were detected in the subsurface soil samples.
PROPOSED PLAN
A Closure Document was approved by NDEP on 22 Nov 1999.
