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 four mayfly species exposed to elevated chloride concentrations at temperatures that range from 5–25 degrees Celsius.
