DNAPL Characterization Methods and Approaches, Part 2: Cost Comparisons`, Ground Water Monitoring & Remediation
Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources worldwide. DNAPL site characterization method performance comparisons are presented in a companion paper (Kram et al. 2001). This study compares the costs for implementing various characterization ...

Direct-Push Injection and Circulation Biobarrier to Remediate a TCE Groundwater Plume
ABSTRACT: The goal of this study was to determine if direct-push drilling methods combined with a circulation system could be used to establish a passive biobarrier in a very transmissive aquifer to treat tricholoroethene (TCE). The Site is located in central Indiana, where historic use of TCE has impacted an unconfined aquifer. A plume consisting primarily of TCE has migrated from west to east ...

Effective distribution of edible oils
Edible oil was injected at five sites to promote reductive dechlorination. The edible oil was injected as a non-aqueous phase liquid (NAPL) or as an emulsion of oil, an emulsifier, and water. At Dover Air Force Base, injection of the emulsion into a barrier resulted in greater distribution of the total organic carbon (TOC) and more rapid dechlorination than direct injection of the edible oil into ...

Full-scale KB-1® Bioaugmented Biobarrier for TCE Plume Containment
Problem DefinitionThe site is a former manufacturing facility, where a historic trichloroethene (TCE) release created a plume 1,100 feet wide and 7,000 feet long averaging 3,600 micrograms per liter (μg/ L) TCE, with a groundwater velocity of about 2 feet per day. Prior to biostimulation with electron donor, the groundwater conditions ranged from aerobic to mildly reducing and Gene-Trac DNA ...
