Impact/Purpose:
Determine the actual concentrations of suspected health-impacting DBPs produced using non-chlorine disinfectants, how often they occur, under what conditions they are formed, and their fate and transport in the distribution system.
Description:
A unified method of detection for seven halogenated furanones present in drinking waters at the ng/L level has been developed. The use of GC/ECD makes this method amenable to manyenvironmental laboratories and water treatment plants in the United States. Detection limits observed using liquid-liquid extraction can be improved significantly by replacing this step with solid phase extraction as a preconcentration method. In order to assess the health risk of halogenated furanones, there is a need to apply this method to real drinking waters and collect occurrence data on the MX-analogues.
