In 2019, US researchers added fluorescent dye to a Pennsylvania mine-water wetland and flew 12 drone missions; a system designed for 29-hour retention held water for only 4.65 hours

Visual observations indicated a retention time of about 61 minutes in Cell 3 and 66 minutes in Cell 4. Monastery Run Wetland 1, near Latrobe, Pennsylvania, was built in 1997-1998 as a passive treatment system for several discharges from an abandoned underground mine. Adequate retention time for iron removal from mine water before discharge to … Read more
