HWAAP-G01A
OLD BOMB OPEN BURN/OPEN DETONATION
GROUND 1
SITE DESCRIPTION
HWAAP-G01A, a waste treatment site, is adjacent to HWAAP-A06A and is located approximately eight miles southeast of the HWAD industrial facility and  one mile northwest of TV Hill. There is significant overlap with A06A and G01A. Together, both cover approximately 50 acres. The site was used from 1940 to the late 1950's to burn and detonate reactive hazardous waste such as mines, warheads, bombs, incendiary devices, miscellaneous ordnance and PEP. The surface of the site had been physically rearranged, and there is one trench measuring 300'x15'x15'. The ground and trench are stained with black ash and rusty-red oxidized TNT residue. Surface flooding could erode into closed cells and move solid waste or leachates downstream to other areas on the alluvial plain surface. The installation completed and submitted a closure plan for this site to the State of Nevada in March 1985. No physical closure activities have occurred. The State deferred action to higher priority sites located in industrial area where workers are more likely to be exposed and groundwater has been impacted. This site is an isolated location and fenced with 24- hour security. Soil sampling performed by USAEHA in 1981 identified explosives. Groundwater samples were reportedly clean in the 1981 Survey and Assessment of HWAD report prepared by USATHAMA. Investigation in 1994 included airborne ground penetrating radar surveying over both A06A and G01A. Forty-four targets were surveyed over a 63 acre area. Also, an Army evaluation team visited the site to determine if the OEW at the site pose an imminent hazard. As result of the evaluation, an imminent threat to human safety was determined and a Risk Assessment Code (RAC) 2 was assigned.
PROPOSED PLAN
This site is an active RCRA permitted site and is not eligible for Installation Restoration Program funds.
