Mining Impacts on Aquatic Ecosystem
From Consulting Services
Historical mining activities have and continue to impact aquatic ecosystems throughout the United States, particularly in the western U.S., where they constitute a significant fraction of “Superfund” sites. And while current mining practices, as well as remediation efforts underway at historical mines, are considerably more “environmentally friendly”, monitoring is still required to ensure protection of the aquatic environment.
Pacific EcoRisk is very experienced in evaluating the variety of environmental problems that may result from mining and mine site remediation activities. This includes evaluation of mercury problems, “acid mine drainage”-related problems, including effects of acidity (reduced pH) and/or metals toxicity, as well as other problems, including accidental releases from holding ponds, sedimentation, wetlands treatment, etc.
Services that we provide in the evaluation of mining impacts include:
- Critical review of technical reports
- Ecological risk assessment
- Preparation of information (e.g., literature) reviews
- Expert witness services
- Aquatic toxicity testing
- Sediment toxicity testing
- Bioaccumulation studies
- Food-chain metals studies
- Site-specific water quality criteria
- Bioassessment of streams/wetlands
