The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund, established the Remedial Investigation and Feasibility Study (RI/FS) process as part of a national effort to clean up hazardous waste sites. Scientists conduct remedial investigations to characterize the nature and extent of contamination at a site and determine whether site contamination presents a significant risk to human health or the environment.
For more than two decades, EAS staff have performed RI/FS at hazardous waste sites. We work with clients to characterize the nature and extent of contamination, assess risk to humans and the environment, and evaluate remedial actions. The legally defensible information EAS provides helps clients develop long-term remedial actions to reduce dangers associated with the contamination.
