This document describes an analytical method, not based on mass spectrometry, for the analysis of haloethers in water and wastewater. The following haloethers were originally included in this study: 2-chloroethyl vinyl ether, bis(2-chloroisopropyl) ether, bis(2-chloroethyl) ether, bis(2-chloroethoxy) methane, 4-chlorophenyl phenyl ether, 4-bromophenyl phenyl ether, and (bischloromethyl) ether. The 2-chloroethyl vinyl ether and the bis(chloromethyl) ether were later deleted from the project because of extreme volatility and hydrolytic instability, respectively. A literature search was conducted to acquire published information on the hydrolytic stability of the haloethers, methods for the detection of haloethers in water, and method for the isolation, concentration, and analysis of haloethers. Gas chromatography studies were completed to compare different packings for use with haloethers and to compare the results obtained using a Hall electrolytic conductivity detection with those obtained using an electron capture detector. The workable method developed in this program for the analysis of haloethers in wastewater consisted of a liquid/liquid extraction using methylene chloride, an evaporation step using Kunderna-Danish (K-D) evaporators, a column chromatographic cleanup procedure using Florisil, another K-D evaporation of the fraction from the Florisil column, and subsequent analysis by gas chromatography using an electrolytic conductivity detector.
