From permitting and design through construction, Geosyntec delivers solutions of exceptional value. From permitting and design through construction, Geosyntec delivers solutions of exceptional value.

Geosyntec is a recognized leader in waste containment facility permitting and design. From concept to implementation, we assist our clients in achieving efficient, safe, and secure containment of their regulated wastes that require land disposal.

Our practitioners assist our clients in increasing commercial viability, achieving and maintaining compliance, and ensuring that short- and long-term needs are met for new and existing sites and projects. We are experienced in the permitting, design, and construction of expansions and closures of:

  • Municipal solid waste (MSW) landfills
  • Hazardous waste landfills
  • Coal combustion residual landfills
  • Construction and demolition waste landfills
  • Radiological and mixed waste landfills
  • Tailings impoundments
  • Mine waste rock piles and dumps

Our waste containment practice specializes in addressing the most complex and challenging projects through our innovative technologies and designs. Our practitioners assist clients with permitting greenfield sites and existing site expansions, maximizing disposal capacity, and solving complex site challenges.   Our practitioners also provide investigation, design, permitting, and construction oversight for on-site disposal facilities for cost-effective, safe on-site disposal of soils, sludges, and miscellaneous debris with a broad range of contaminants, including mercury, PCBs, and volatile and semi-volatile organic compounds.

Advancing the State of the Practice

The applied research of our practitioners has defined the state of the practice for more than 30 years. Through our close relationships and collaborative efforts with both government entities and academic institutions, Geosyntec is often first-to-field with emerging technologies and practices, and many of the waste containment design and methodologies we pioneered in the 1980s are now today's standards in the field. From developing guidance documents and guidelines for the U.S. Environmental Protection Agency (EPA), Environmental Research and Education Foundation (EREF), and the Interstate Technology & Regulatory Council (ITRC), to partnering with academic institutions such as the University of Illinois and Drexel University, we continuously look to increase the efficiency, safety, and security of waste containment facilities and projects.
