United States delays enforcement of stricter water standards
Tap title to read story
The United States Environmental Protection Agency (EPA) on May 20, 2026, formally published rules pushing back key tap water chemical safety deadlines to 2031, extending a long-running regulatory struggle over toxic contaminants. The delay affects enforcement of strict limits, including a 2024 federal standard of four parts per trillion on two persistent chemicals linked to cancer and low birth weight, covering water systems that serve about 100 million Americans. The underlying conflict dates to the 1974 Safe Drinking Water Act, which created extensive procedures that slow new limits and fuel clashes among regulators, chemical manufacturers, and financially strained municipal utilities.
