Study explores long-term water quality trends in near-pristine streams

For the first time, a study has compared water quality trends in forested streams across the country that are largely undisturbed by land use or land cover changes. "Much of what we know about changes in stream water quality comes from studies where basins have been impacted by human activity," said Alba Argerich, a postdoctoral research associate with the College of Forestry and the study's lead author. "Our work intentionally focused on relatively undisturbed streams, the very reference sites that serve as benchmarks for evaluating water quality trends."
