Contaminated Sites

The management of contaminated sites continues to be a significant problem in the United States and globally, particularly as urbanization pushes cities and municipalities to reclaim former industrial properties for new uses. LimnoTech has provided services in the area of site characterization, remediation, and management since the earliest days of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), serving clients in both the regulated and regulatory communities at hundreds of sites in the United States and internationally.

Environmental site characterization and remediation involves identifying and reducing or eliminating potential threats to human health and the environment from contamination. Site characterization and remedy design can range from simple to complex, depending on the contaminants, transport pathways and potential receptors at risk. Remediation may involve engineered cleanups or containment of contaminated soil, groundwater, surface water, sediments, or man-made structures. In some cases, it is prudent to monitor and manage a site, allowing natural processes to degrade contaminants and recovery to occur.

To address the full range of problems and approaches, LimnoTech brings world-class expertise in many disciplines, including the natural sciences, engineering, economics, regulatory compliance, and business management. We also have the capabilities to support the full conversion of contaminated sites to new uses with our complementary expertise in water resource restoration and urban land revitalization.
