This June, ERD is expected to begin the excavation of 51 waste pits near the Lab's Former Landfill in Operable Unit I.
The Chemical/Animal Pits and Glass Holes were used from the mid-1950s to 1980 for the disposal of laboratory chemical containers, glassware and animal carcasses. Soil and groundwater contamination has been detected in the areas adjacent to the pits.
After the pits are excavated, the waste will be sorted and disposed of on- or off-site as determined by cleanup criteria.
A comparison of remediation alternatives considered for this area is documented in the Evaluation of Alternatives report, available in local repositories (for locations, see page 11).
The public comment period on the report runs from April 23 to May 23, 1997.
