Chloride concentrations in surface waters have been increasing over the last several decades at multiple locations throughout the United States. At times, it appears that ambient chloride concentrations now reach levels that may have a negative effect on aquatic organisms. This project measures responses of six mayfly species exposed to elevated chloride concentrations in water from three Exceptional Value streams in Pennsylvania as well as in White Clay Creek at the Stroud Center.
