A method for reducing purge volumes in deep monitoring wells: a purging experiment.
Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...

Co‐occurrence of 1,4‐dioxane with trichloroethylene in chlorinated solvent groundwater plumes at US Air Force installations: Fact or fiction
Increasing regulatory attention to 1,4‐dioxane has prompted the United States Air Force (USAF) to evaluate potential environmental liabilities, primarily associated with legacy contamination, at an enterprise scale. Although accurately quantifying environmental liability is operationally difficult given limited historic environmental monitoring data, 1,4‐dioxane is a known constituent (i.e., ...

TCE plume management through edible oil injection and natural attenuation
Two pilot-scale edible oil barriers were constructed in the upper portion of a 1,500 m long chlorinated solvent plume at Dover Air Force Base (AFB), DE. Edible soybean oil was injected into two 6.1 m-long barriers with monitoring wells spaced up to 4.6 m downgradient. Barrier 1 was treated by low pressure, direct injection of soybean oil into ten wells spaced 0.6 m apart. After eight months, a ...

TCE Source Area Remediation at a Former Manufacturing Facility Confidential Client – Western Connecticut - Case Study
Project Summary TRS Group, Inc. (TRS), as a subcontractor to AECOM, completed a Standard Fixed Price Remediation (SFPR) of trichloroethene (TCE) in groundwater in Western Connecticut using Electrical Resistance Heating (ERH). The objective of the ERH project was to achieve the prescribed remediation goal for dissolved TCE in groundwater within the treatment volume. The system incorporated 89 ...
