1. IntroductionThe US Congress passed, and President Richard Nixon signed intolaw the Safe Drinking Water Act in 1974. A significant provision of theAct involved engaging the US NAS to advise the EPA on multiple sci-entific and technical areas such as chemical and radiation risk assess-ment, including cancer risk assessment. To achieve these goals the NAScreated the Safe Drinking Water Committee (SDWC) in 1975. In 1977the SDWC published the 700 pageDrinking Water and Health reportoffering EPA widespread guidance, including cancer risk assessmentand its underlying scientific foundations that supported the LNT.Within two years EPA would issue the first national drinking waterstandard for a chemical carcinogen using the LNT for total trihalo-methanes (THM) . This action would jump start an avalanche ofother LNT based cancer risk assessments by EPA, not just for drinkingwater but for other environmental media as well.
