Wetlands could be key in revitalizing acid streams, UT Arlington researchers say

A team of University of Texas at Arlington  biologists working with the U.S. Geological Survey has found that watershed wetlands can serve as a natural source for the improvement of streams polluted by acid rain. The group, led by associate professor of biology Sophia Passy, also contends that recent increases in the level of organic matter in surface waters in regions of North America and Europe – also known as “brownification” – holds benefits for aquatic ecosystems. The research team’s work appears in the September issue of the journal Global Change Biology (
