DC Water Monitors July 4 Fireworks as 8 Potomac Barges Raise Pollution Risks

Summary
DC Water said its incident team will activate for July 4, with field staff staged to respond during fireworks launched from the National Mall, West Potomac Park and eight Potomac River barges.
Drought conditions could keep contaminants in the river longer than usual, researchers said, with tidal flows near Theodore Roosevelt Island able to trap Perchlorates from fireworks rather than flush them downstream quickly.
Perchlorates can disrupt development in amphibians and juvenile fish, while loud blasts during breeding season can drive Ospreys from nests and leave chicks exposed to predators.
Heavy metals used to create fireworks colors also pose health risks; a 2020 study found troubling lead levels in some fireworks exhaust, and U.S. fireworks consumption has more than doubled in 25 years.
