Drum Disposal Area
Test Pit Program
Objective was to characterize the contamination within the DDA and determine
the extent of the waste deposits
Field work took place in early 1992 and consisted of 11 test pit excavations:
- 6 from the Stacked Drum Area
- 3 from the Non-Intact Drum Area
- 2 from the Iron Filings Area
Stacked Drum Area
Test Pit Program Results
315 drums were removed from the Stacked Drum Area. The majority of the drums removed were intact and in good condition.
All drums were transported off-site to a treatment and disposal facility
