To require additional research prior to the promulgation of a standard for sulfate under the Safe Drinking Water Act, and for other purposes.

Requires the Administrator of the Environmental Protection Agency and the Director of the Centers for Disease Control, prior to promulgating a national primary drinking water regulation for sulfate, to jointly conduct additional research to establish a reliable dose-response relationship for the adverse health effects that may result from exposure to sulfate in drinking water.

Sets forth provisions regarding: (1) consideration of health effects that may be experienced by groups within the general population, such as infants and travelers, that are potentially at greater risk; (2) the conduct of research in consultation with interested States and based on the best available, peer-reviewed science and supporting studies; and (3) notice, time, and rulemaking requirements for promulgating such standard.
