Summary

The EPA has banned TCE and perc, toxic chemicals linked to cancer, liver and kidney damage, and other severe health issues.

Widely used in dry cleaning, degreasers, and consumer products, these substances have contaminated groundwater and air, particularly near military bases.

The ban, which reverses Trump-era rollbacks and surpasses Obama-era proposals, has been welcomed by public health advocates but opposed by industry groups.

The four-year timeline to undo the ban makes it difficult for the incoming Trump administration to reverse, despite its intent to loosen chemical regulations.
