Abstract:

In 1980, the Comprehensive Environmental Response, Compensation, and Liability Act CERCLA was signed into law. It was later amended by the Superfund Amendments and Reauthorization Act SARA of 1986. Under CERCLA and modified by SARA, a National Priority List NPL of hazardous waste sites was established, along with specific guidelines for the clean-up of these sites. The clean up process involves much more than just the actual site remediation work it includes everything from a preliminary assessment and initial inspection of the site, to remedial design and action. The remedial investigation RI is conducted to characterize site conditions and conduct treatability investigations. This paper will focus solely on the site characterization evaluation requirements as part of the RI step leading to the clean up process. According to the Environmental Protection Agency EPA, there are four objectives in site characterization. They are conducting the field investigation, defining the nature and extent of contamination, identifying FederalState contaminant and location specific ARARs Applicable or Relevant and Appropriate Requirements, and developing baseline risk assessments.
