The paper reports on the feasibility of utilizing a chlorinated humic acid byproduct database, developed inhouse, as a drinking water quality screening tool. Specifically, a GC/MS database of over 780 compounds identified during experiments involving the reaction of humic acids with chlorine has been compiled and systematically compared to GC/MS profiles from extracts of finished drinking water from 10 preselected operating utilities. A major goal of the research was to narrow this down to a smaller, more significant target compound list which would be representative of some of the most frequently encountered chlorination byproducts in the finished drinking water of utilities practicing chlorine disinfection. In addition, the study demonstrates the practicality of using the described methodology for concentrating and identifying specific compounds from water samples at low concentrations.
