40 YEARS AND 3-PLUS MILLION GALLONS LATER A CASE STUDY ON THE HARTFORD, ILLINOIS AREA GROUNDWATER PLUME SITE

Abstract

ABSTRACT An estimated 3.4 million gallons of leaded gasoline, diesel fuel and other refined and unrefined products from buried pipeline systems and several refineries have affected a residential area of 200 plus homes and businesses. U.S. EPA tasked a consortium of energy companies to develop a rapid response program to quickly eliminate intermittent vapor intrusion problems and to ultimately remove the petroleum products plume. The project involved coordinating efforts between several energy companies, the U.S. EPA, the Illinois EPA, the Illinois Department of Public Health and ATSDR. Some of the innovative technologies utilized include the laser fluorescence Rapid Optical Screening Tool (ROST™), soil vapor extraction (SVE), oil skimming and bio slurping. Managing data decision uncertainties, through the compilation of historical data into a site conceptual model was used to develop a dynamic site cleanup strategy and managing rapidly evolving field data by GIS digital mapping and data collection systems.
