A new study shows streams and rivers up and down the East Coast are threatened by a legacy of acid rain and the impact of human activities. WAMC’s Hudson Valley Bureau Chief Allison Dunne spoke with one of the study’s authors.

Dr. Gene Likens, co-discoverer of acid rain in North America some 50 years ago, says the study is the first of its kind. Researchers looked at long-term alkalinity trends in 97 streams and rivers from Florida to New Hampshire, and found alkalinity has increased.
