Chlorinated solvents are man-made compounds that have been used for years in both the military and commercial sectors for cleaning and degreasing many products and equipment ranging from aircraft engines, automobile and truck parts, electronic components and clothing. Unfortunately, spillage of these chemicals into soil has created serious hazards to human health, particularly when the solvent migrates through the soil and contaminates aquifers.

In terms of remediation, chlorinated solvents are more problematic than most petroleum, oil, & lubricants (POLs). POLs are derived from naturally-occurring hydrocarbons that are lighter than water and are degradable under a wide spectrum of geochemical conditions ranging from highly aerobic to highly anaerobic. Chlorinated solvents, however, because of their physical & chemical properties, are relatively recalcitrant in the subsurface, are more difficult to access once they are in the ground, and take longer to remediate. Chlorinated solvents are oxidized synthetic compounds, which makes them susceptible to degradation by reductive processes under anaerobic conditions, either ambient or enhanced. The cost of remediating chlorinated solvents sites may significantly exceed the cost of remediating POL sites. Specifically, if chlorinated solvents are released to the subsurface as a dense non-aqueous phase liquid (DNAPL), the density of the DNAPL relative to water will lead to a complex distribution of the contaminant in the vadose & saturated zones.

This course is intended for environmental engineers who wish to expand their knowledge of alternative methods of site remediation. In particular, this course presents a relatively new remediation technique, in which edible oil, either as pure liquid or emulsified mixture, is injected into the subsurface to stimulate in situ anaerobic biodegradation of chlorinated solvents.
