Lower trihalomethane (THM) standards may force many drinking water utilities to change disinfectants or consider using various treatment technologies ranging from conventional treatment to granular activated carbon (GAC) adsorption. Extensive performance and cost data have been collected during GAC field-scale research by the U.S. Environmental Protection Agency's (USEPA) Drinking Water Research Division. GAC has been shown to be a possible treatment alternative for meeting somewhat lower THM concentrations. However, GAC will not be effective for all situations. The cost of GAC treatment varied for each location evaluated with about 15 cents/1,000 gal being the lower value. One would have to evaluate this cost with other treatment alternatives for controlling THMs, taking into account disinfection byproducts other than THMs and any other detrimental effects.
