This book provides environmental managers and their supporting technical specialists with a comprehensive strategy for cost-effectively cleaning up soils and groundwater contaminated by petroleum releases. It includes the most recent advances in site investigation techniques, low-cost remedial approaches, and technologies.
It uses a "risk-based" process to answer key questions involved in developing a remediation or closure plan for a petroleum spill site. Several approaches are described that include risk management methods which use institutional controls to isolate contaminates from human contact and long-term monitoring to verify that natural attenuation is reducing future risk. More traditional risk evaluations and simplified RCBA methods are presented that use site-specific exposure assumptions to develop risk-based cleanup objectives. Case studies illustrate how various combinations of land-use control, site-specific risk analysis, natural attenuation and focused source reduction technologies have been used to obtain risk-based closures at sites across the United States.
