The agency’s move is the latest in a more than decade-long battle over whether to regulate perchlorate. The EPA said that the public benefit of the regulation did not justify its expected cost.“Due to infrequent perchlorate levels of health concern, the vast majority of the approximately 66,000 water systems that would be subject to the rule will incur substantial administrative and monitoring costs with limited or no corresponding public health benefits as a whole,” the agency wrote in its proposal. Perchlorate is used to make rockets, fireworks and other explosives, although it can also occur naturally. At some defense, aerospace and manufacturing sites, it seeped into nearby groundwater where it could spread, a problem that has been concentrated in the Southwest and along sections of the East Coast. Perchlorate is a concern because it affects the function of the thyroid, which can be particularly detrimental for the development of young children, lowering IQ scores and increasing rates of behavioral problems. Based on estimates that perchlorate could be in the drinking water of roughly 16 million people, the EPA determined in 2011 that it was a sufficient threat to public health that it needed to be regulated. Under the Safe Drinking Water Act, this determination required the EPA to propose and then finalize regulations by strict deadlines, with a proposal due in two years. It didn’t happen. First, the agency updated the science to better estimate perchlorate’s risks, but that took time. By 2016, the nonprofit Natural Resources Defense Council sued to force action. During the first Trump administration, the EPA proposed a never-implemented standard that the NRDC said was less restrictive than any state limit and would lead to IQ point loss in children., saying no standard was necessary because a new analysis had found the chemical was less dangerous and its appearance in drinking water less common than previously thought. That's still the agency's position. It said Monday that its data shows perchlorate is not widespread in drinking water. “We anticipate that fewer than one‑tenth of 1% of regulated water systems are likely to find perchlorate above the proposed limits,” the agency said. A limit will help the small number of places with a problem, but burden the vast majority with costs they don't need, officials said. The NRDC challenged that reversal and a federal appeals court said the EPA must propose a regulation for perchlorate, arguing that it still is a significant and widespread public health threat. The agency will solicit public comment on limits of 20, 40 and 80 parts per billion, as well as other elements of the proposal. “Members of the public deserve to know whether there’s rocket fuel in their tap water. We’re pleased to see that, however reluctantly, EPA is moving one step closer to providing the public with that information,” said Sarah Fort, a senior attorney with NRDC. EPA Administrator Lee Zeldin has sought massive rollbacks of environmental rules and promoted oil and gas development. But on drinking water, the agency’s actions have been more moderate.
