Halogenated Alkanes
Ethylene Dibromide
Ethylene Dibromide (EDB) is a volatile halogenated organic and as such is subject to most standard characterization and analytical techniques used on this class of chemicals. Methods such as vertical profiling, membrane interface probe, and standard GC/MS are discussed in the main section for DNAPLs detection and site characterization.
Diffusion Samplers
While Diffusion Samplers have been used mostly for chlorinated ethenes and BTEX, they have been found to work for EDB (ITRC 2004).
Laboratory Methods
The maximum contaminant level (MCL) for EDB is 0.05 µg/L. Special handling procedures for GC and GC/MS methods likely will be needed to obtain this detection level.

SW-846 Method 8011: 1,2-Dibromoethane and 1,2-Dibromo-3-Chloropropane by Microextraction and Gas Chromatography
This method is applicable to the determination of 1,2-dibromoethane and 1,2-dibromo-3-chloropropane in drinking water and groundwater.

Field Screening Methods
No commercially available EDB-specific methods were found. The maximum contaminant level (MCL) for EDB in drinking water is 0.05 µg/L, which generally is too low for screening methodologies.
