As environmental lawyers, one of our passions is fighting for clean drinking water for communities affected by contamination. So, it is disappointing that the EPA, under President Biden, has endorsed a Trump administration decision and decided not to regulate perchlorate in drinking water.
What is Perchlorate?
Perchlorate is a contaminant that can be found in groundwater, surface water, and soil. Most perchlorate manufactured in the U.S. is used for rockets and missiles. Perchlorate-based chemicals are also used in safety flares, fireworks, matches, pyrotechnics, explosives, and batteries. Because perchlorates are used in military applications, some countries prefer to keep the amounts they make confidential. So, we do not know the exact amount of perchlorates produced or used in the United States. However, high levels of perchlorates are often found near military bases where the chemicals have been used in rocket fuel. And to no one’s surprise, the Department of Defense and other military contractors oppose limiting perchlorate in drinking water.
