Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
Pages 4

Risk assessment has been defined by the National Academy of Sciences as "the use of available scientific information and reasonable scientific assumptions to evaluate the health risk to people from exposure to hazardous materials and situations in the environment."' The unknown or uncertain conditions often inherent in hazardous waste site remediation projects complicate the job of the responsible professional to adequately assess and manage associated risks. This paper describes the design and implementation of a risk-based remedial action program for the removal of pentachlorophenol sludges at a dioxin-contaminated site in the midwest.
