"EPA Implements National Standard for Limiting 'Forever Chemicals' in Drinking Water"

The EPA has established the first-ever drinking water standard for "forever chemicals" known as PFAS, which can pose health risks even at low levels of exposure. The new rule aims to reduce PFAS exposure for about 100 million people and requires water utilities to test for and reduce levels of certain PFAS to 4 parts per trillion or less. While the regulation is estimated to cost water utilities around $1.5 billion per year, the Biden administration has allocated funds to address PFAS contamination in water systems. Environmental groups have praised the action, while the water industry has expressed concerns about the costs falling on customers.
