Evaluating a Hazardous Waste Site Examining the Potential for Migration of Contaminants
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 Federal/State contaminant and location specific ARAR's (Applicable or Relevant and Appropriate Requirements), and developing baseline risk assessments.
