Utilities are currently evaluating membranes and GAC for DBP precursor removal. Under the treatment study requirement of the Information Collection Rule, 493 treatment plants were required to monitor total organic carbon (TOC) concentrations in their influent or finished water to determine whether studies evaluating granular activated carbon or membranes would be required. These TOC results were aggregated and analyzed by source water type, treatment type, disinfection practices, and geographic location. Seventy‐eight percent of these plants met the criteria to avoid the treatment study requirement. The remaining plants will be required to conduct new treatment studies, submit data from previous studies, or contribute funds to a cooperative research effort. Under the treatment study requirement, 62 granular activated carbon studies and 37 membranes studies will be conducted.
