Trends and uses of ecological risk assessments in the USEPA Region 5 Superfund program

OSTI ID:367503
Ecological risk assessments (ERAs) have been used in the USEPA Superfund program for approximately five years to determine effects of hazardous waste sites on ecological receptors. The methods used for evaluation of the risks, as well as the receptors evaluated, have varied over the years as ERA methods have developed and become more refined. In many cases, the assessments have become more complex, recognizing a greater stake in, and understanding of the discipline. The USEPA Region 5 office of Superfund has developed three types of ERAs from screening level to full ERAs to address the differing requirements of each stage of the Superfund process. The different types of ERAs will be presented, along with a description of the intended uses of each type of ERA. Additionally, information regarding the various types of assessments that have been performed in the past on Region 5 Superfund sites will also be discussed. The information will be presented with respect to the differing categories of sites (i.e. pre-remedial, remedial, and removal) in Region 5.
