This site addresses Soil Vapor Extraction (SVE), a process used to draw chemicals in vapor form out of contaminated soil. Communities living near contaminated sites want information regarding potential for exposures to hazardous chemicals. Concerns such as emissions of dioxins and other potential byproducts from the treatment of off-gas from soil vapor extraction systems, as well as alternative technologies that can sometimes be used in place of SVE are also covered at this web site.
Types of information that you will find on these pages: Ž Conventional emission control technologies, such as thermal or catalytic oxidation Ž Alternative vapor emission controls and alternatives to SVE treatment Ž Check list of questions for communities to consider when faced with the possible need for SVE Ž A FACT SHEET on SVE and links to additional sources of relevant information. |
