Fuel releases that impact groundwater are a common occurrence, and the growing use of
ethanol as a transportation biofuel is increasing the likelihood of encountering ethanol in …

At contaminated sites, indoor inhalation of volatile organic compounds from groundwater
contamination, known as vapor intrusion (VI), is an important exposure pathway to …

Fuel ethanol releases can stimulate methanogenesis in impacted aquifers, which could
pose an explosion risk if methane migrates into enclosed spaces where ignitable conditions …

The potential groundwater impacts of biodiesel releases have received limited attention
despite the increasing probability of such events. In this work, microcosms were prepared …

Soil moisture content continuously alters the types and forms of petroleum organic pollutants
in the soil through processes such as dissolution, convection, and dilution, forming complex …

Surfactants can aid subsurface remediation through three primary mechanisms-
solubilization, mobilization and/or emulsification. Among these mechanisms, emulsification …

Hundreds of groundwater samples were collected at E95 (95% ethanol, 5% gasoline) train
derailment spills in Balaton and Cambria, Minnesota and South Hutchinson, Kansas. Most …

Ethanol (EtOH), an emerging contaminant with potential direct and indirect environmental
effects, poses threats to water supplies when spilled in large volumes. A series of …

Fuel mixtures composed of gasoline and ethanol are lighter than water and, if enough
volume is released into the unsaturated zone, they accumulate in the capillary fringe, acting …

Oxygenates present in gasoline, such as ethanol and MTBE, are a concern in subsurface
contamination related to accidental spills. While gasoline hydrocarbon compounds have low …
