This powerpoint presentation begins by presenting a brief overview of the presentation, including the following: new epidemiology studies; regulatory context and constraints; balancing and simultaneous compliance; regulatory development; possible regulatory implications; issues needing clarification; and, which regulatory approach. Presentation conclusions indicate the following: analytical techniques are becoming more sophisticated, but are still in research stages; we are able to see very low levels of many DBPs; occurrence data are limited because of the absence of standards and robust analytical techniques that can be used nationally; lack of these analytical methods also limit studies on mechanisms of formation and on treatment; health effects studies are not keeping up with the analytical work; we need to continue the research to better understand these emerging DBPs relative to the "established" DBPs; and, respective indicator value relative to epi findings is critical. Includes table, figures.
