NORTH BURN PADS LANDFILL

 

SITE DESCRIPTION

The North Burn Pads Landfill measures approximately 75 x 475 feet and was used to receive the remnants (reported to be flashed cans and containers) from the North Burn Pads. Landfill activities occurred from 1968 to 1972.

A cleanup operation was performed in 1980 during which some of the contents of the landfill were taken to the Inert Disposal Area.

Results from the SI in 1991 did not indicate significant contamination; however, RI work was initiated to fill data gaps. RI work completed in May 1996 found metals in soil and groundwater. Pre-design sampling in 1997/8 found high levels of explosives in soil and leachate. Groundwater monitoring began in 1994.

RDX in concentrations of less than 10 ppb have been found in the groundwater in upper bedrock (30- 40 feet bgs).

The IRA work in 1998 removed 13,890cy of contaminated soils and debris and placed it in the appropriate areas at the Inert Disposal Area (IAAP-020).

The FUSRAP PA identified this area as requiring additional investigation. In August 2004, FUSRAP conducted a screening survey of this site to determine if radiological contaminates from AEC activities are present in soil. Preliminary assessments of all screening results indicate no radiological contamination present at this area.

This site is considered Response Complete and requires no further action under the IRP as documented in the Phase 1 Remedial Action Report. This site will be included in the OU3 Groundwater ROD.
