Field Implementation of Bioremediation at INDOT Facilities-Phase I

Abstract

were to increase utilization of bioremediation by INDOT and other agencies for the remediation of petroleum contaminated sites, reduce uncertainty associated with the design and implementation of bioremediation systems, reduce reliance on landfills for disposal of contaminated soils, reduce long-term liability associated witii hazardous v,aste. and to improve the quality of engineering science utilized for the design of bioremediation systems. In addition, a guidance manual for remediation decision makers was developed. The benefits of achieving these objectives will be to decrease costs associated with Leaking Underground Storage Tank (LUST) remediation, improve environmental qualit>-, and to improve pubhc and environmental health. To achieve the objectives outiined above several bioremediation field demonstrations were successfully developed. A bioremediation field demonstration using Monitored Natural .•\ttenuation was implemented and is an ongoing project at Linton, Indiana. A land farming field demonstration using excavated low hydraulic conducti%-ity soils has been completed at Chrisney, Indiana. An engineered bioremediation field demonstration at a site with contaminated groundwater using a combined Air Sparging-Soil Vapor Extraction system is underway at Shoals, Indiana.17.
