Description
The Granite Mine is an abandoned mine complex with historical significance. It is located in a remote area in Prince William Sound and within the boundaries of a Wilderness Study Area. Project objectives included:
- Characterize media (soil and drum contents) for hazardous constituents.
- Identify and remove deteriorated containers with hazardous material.
- Remediate and dispose of soil contaminated from leaking drums.
Scope of Work
The Bethel team worked closely with onsite Forest Service personnel to implement project objectives. Specific work scope elements included:
- Located, surveyed, and removed 64 empty and deteriorated drums.
- Collected waste characterization samples from contaminated soil and drums.
- Overpacked and removed four drums containing petroleum product.
- Excavated 2,000 lbs. of soil contaminated with hydrocarbons and metals.
- Collected confirmation samples to demonstrate efficacy of remediation.
- Removed miscellaneous debris determined not to be culturally sensitive.
- Managed and disposed of waste in compliance with Federal and State regulations
Unique Challenges
The physical and historical setting of Granite Mine presented unique challenges including mitigating hazards associated with the remote location, inclement weather, and wildlife. The site was only accessable at high tide via landing craft, requiring precise daily logistics and coordination. Motorized equipment was not allowed due to the land status; all project activities were conducted manually, with handcarts, small tools, shovels, and rope winches.
