Abstract
A large volume water extraction device was used to determine concentrations of chlorinated dibenzo-p-dioxins (CDDs) and chlorinated dibenzofurans (CDFs) in surface water sampled near known chemical dump sites. Results using the APLE extraction device were similar to those obtained by conventional liquid/liquid extraction. Total CDD and CDF levels in the water were in the low parts-per-billion (ppb) range, while levels in the suspended particulates centrifuged from the water were 10 times greater.
