Treatment Technologies

Soil Vapor Extraction and Air Sparging

Halogenated Monoaromatics

Chlorobenzene, 1,2-Dichlorobenzene, 1,3-Dichlorobenzene, and 1,2,4-Trichlorobenzene are considered amenable to soil vapor extraction technologies (USACE 2002).

Example Sites

ARKEMA, Inc., Portland, Oregon
Oregon Department of Environmental Quality, Environmental Cleanup Site Information (ECSI) Database Site Summary Report.

Pennsylvania Salt Manufacturing began manufacturing operations at the site in 1941 and ceased in 2001. The facility produced various chemicals, including sodium chlorate, potassium chlorate, chlorine, sodium hydroxide, DDT, sodium orthosilicate, magnesium chloride hexahydrate, ammonia, hydrogen, ammonium and sodium perchlorate (rocket fuel), and hydrochloric acid. The major contaminants of concern are DDT, chlorobenzene (DNAPL), and hexavalent chromium. SVE and ISCO (sodium persulfate) were chosen to treat the chlorobenzene and DDT.

Jadco Hughes Facility, Belmont, North Carolina
U.S. EPA, Superfund Site Progress Profile.

The 6-acre Jadco-Hughes Superfund Site was used as a solvent reclamation and waste storage facility. The contaminants of concern include numerous volatile and semivolatile organics, including various chlorobenzenes. SVE and groundwater pump and treat were chosen as the active treatment technologies.
