A GC/MS method for the analysis of DNAPL contamination in the range 10ppm to 2000ppm. December 1996.

Analysii of chlorinated hydrocarbons (DNAPLs) at contaminated sites is routinely effected to detect the presence of dissolved phase material at the low concentrations representative of regulatory compliance limits. The analysis techniques developed for these low levels are not suitable for use in highly contaminated sites. Ths paper details the the development and methodology used to analyse a range of chlorinated hydrocarbons (CFM; CTS; 1,1,1,TCA; TCE; 1,2,DCA; PCE; 1,1,2,2,PCA; HCA; HCBD and HCB) in cores of contaminated aeolian and alluvial sands
