Our Services - Solid & Hazardous Waste Management
Our staff have the requisite qualifications and experience to assist clients with environmental characterization, design, and construction for new, operating, and closed waste disposal facilities.
Service Highlight - Coal Ash Management
Our expertise in coal ash and coal combustion product (CCP) management is unmatched. Our base of electric utility clients and our research work for the Electric Power Research Institute (EPRI) gives us unique insights on analysis techniques and solutions available for addressing coal ash management challenges:
- Hydrogeologic studies for permitting new CCP landfills and expansions
- Hydrogeologic studies and engineering analysis for design, construction, and closure/remediation of operating facilities, legacy sites, and beneficial use sites
- Coal ash landfill and impoundment liner and cover design, construction, and quality assurance testing
- Research and application of research on coal ash leaching and the fate and transport of constituents in leachate when released to the environment
We are active members of the American Coal Ash Association (ACAA) and participate on committees designed to be proactive in maintaining fair and scientifically sound rules and regulations pertaining to the use of CCP products as well as responsible environmental management. Members of our staff regularly present at the World of Coal Ash Conference. Contact Bruce Hensel, Vice President and Principal Scientist for further insights on the state of environmental practices in the coal ash industry.
