Biological solutions for historic mine site remediation
Biological solutions for historic mine site remediation
Thousands of abandoned mine sites across the country continue to pollute waterways and pose safety hazards. The national cleanup cost exceeds $50 billion. Traditional remediation approaches are prohibitively expensive. The Good Samaritan Act (December 2024) creates new pathways for willing parties to clean up these sites without assuming perpetual liability.
Our treatment achieves significant reductions in mining-related contaminants.
| Contaminant | Before | After | Reduction |
|---|---|---|---|
| WAD Cyanide | 21 mg/L | 0.32 mg/L | 98.5% |
| Mercury | 0.012 mg/L | <0.0001 mg/L | >99% |
| Copper | 0.60 mg/L | <0.050 mg/L | >91% |
| Arsenic | 0.20 mg/L | 0.070 mg/L | 65% |
| Selenium | 0.12 mg/L | 0.036 mg/L | 70% |
Our integrated biologic + biochar treatment typically delivers 20–50% cost savings compared to traditional chemical methods — significantly reducing capital and operational costs.
Biochar sequesters contaminants in stable form and our microbial consortia metabolize them biologically — no toxic sludge, no new waste streams requiring disposal.
Biochar naturally immobilizes contaminants and our microbial consortia restore biological activity — no harmful chemicals introduced into fragile watersheds or ecosystems.
Our biologic + biochar approach meets the ecological performance standards required under the Good Samaritan Act, enabling voluntary cleanup without perpetual liability.
Let us collect water and soil samples from target mine sites and develop a customized treatment protocol.
