Regulatory Update: EPA denies petition to ban water fluoridation chemical

Yesterday the U.S. Environmental Protection Agency announced the availability of its response to a Toxic Substances Control Act (Section 21 petition that asked the agency to take action to ban the use of hydrofluorosilicic acid as a water fluoridation agent. EPA denied the petition. The petitioners, a group of American University students, alumni and faculty, claimed that HFSA leads to the contamination of drinking water with arsenic, lead and radionuclides and that an existing alternative source of fluoride, pharmaceutical grade sodium fluoride, would not contribute to drinking water levels of arsenic, lead or radionuclides comparable to those in HFSA. EPA concluded that the petitioners did not set forth sufficient facts to establish that HFSA presents or will present an unreasonable risk and that it is necessary to initiate a TSCA section 6(a) rulemaking to protect adequately against such risk.
