On 15 June 2022, the U.S. Environmental Protection Agency (EPA) released new drinking water lifetime health advisory levels (HALs) for four PFAS compounds. This represents a next step toward implementing awaited federal maximum contaminant levels (MCLs). The HALs serve as non-regulatory thresholds above which the EPA deems exposure can cause detrimental health effects.
In this Research Note:
- New levels heighten pressure on state regulators
- Municipal water accelerates toward solutions beyond GAC
- Progress on water quality brings wastewater streams into regulatory line of site
