The coal combustion residual (CCR) rule mandates obligations for managing the potential impacts of inorganic constituents (sourced from coal ash landfills and surface impoundments) in groundwater and surface water. Our team brings decades of industry experience and a research/academic-level understanding of geologic and geochemical controls on inorganic constituent fate and transport in surface and groundwater, providing our clients with robust and defendable project outcomes. Our team monitors frequently evolving CCR Rule compliance obligations to assist our clients in developing the right solutions. Our recent project experience includes work in Indiana, Kentucky, West Virginia, and Texas.
Recent CCR project work has included:
- Alternate source demonstrations.
- Fly ash impoundment monitoring well network design and installation.
- Bottom ash impoundment monitoring well network design and installation.
- Background groundwater sampling and monitoring.
- Compliance groundwater sampling and monitoring.
- Ash depth investigations.
- CCR management unit compliance.
