EPA’s Proposal for Limiting Rocket Fuel in Drinking Water Is Dangerous to Public Health

After a decade of delay, the U.S. Environmental Protection Agency (EPA) finally proposed a limit for levels of the toxic chemical perchlorate (a component of rocket fuel) in drinking water — except the newly proposed standard of 56 parts per billion is 10 to 50 times higher than what scientists recommend.


"This is enough to make you sick — literally," said Erik Olson, senior director for Health and Food at NRDC, which sued the agency in early 2016 to force it to take action on perchlorate.

Widely used by the military and defense industries, as well as in fireworks and explosives, perchlorate is highly soluble in water and can move quickly into ground- and surface water once it reaches soil. Even low levels of exposure to the chemical can impair hormone production critical to brain development. "Fetuses and infants are especially vulnerable to harm from perchlorate," said Olson. The chemical has been detected in drinking water systems that serve up to 16.6 million Americans — posing significant health risks for children and pregnant women.

Multiple states have lower standards for perchlorate in drinking water that align with the science, like Massachusetts (2 parts per billion) and California (6 parts per billion).

"This is another Trump administration gift to polluters and water utilities that have lobbied to be off the hook for cleaning up the problem," Olson said.

Investment in U.S. offshore wind projects are set to hit $78 billion (€69 billion) this decade, in contrast with an estimated $82 billion for U.S. offshore oil and gasoline projects, Wood Mackenzie data shows. This would be a remarkable feat only four years after the first offshore wind plant — the 30 megawatt (MW) Block Island Wind Farm off the coast of Rhode Island — started operating in U.S. waters.

The COVID-19 pandemic has revealed both the strengths and limitations of globalization. The crisis has made people aware of how industrialized food production can be, and just how far food can travel to get to the local supermarket. There are many benefits to this system, including low prices for consumers and larger, even global, markets for producers. But there are also costs — to the environment, workers, small farmers and to a region or individual nation's food security.
