‘Forever chemicals’ found in 76% of Pennsylvania streams sampled

Pennsylvania is known by anglers and outdoor enthusiasts for its thousands of miles of streams and rivers that lace the rugged Allegheny Mountains, rolling farmlands, and cities such as Pittsburgh and Philadelphia. Many of those waterways supply drinking water for millions.

But a study by the U.S. Geological Survey found that many of those waterways are also tainted by so-called forever chemicals.
