Coast Guard personnel were dispatched to Otter Creek in Bristol on Saturday afternoon after a chemical release there. The hazardous material came from a pipe rupture at Trinseo PLC, a chemical plant in the area. Approximately 8,100 gallons of latex finishing material, which is a water-soluble acrylic polymer solution, was released into the creek. Despite the rain that made recovery efforts more complicated, environmental experts have emphasized that the material shouldn't pose a threat to the public as it is similar to paint material found in most households. The estimated amount released will be updated as response and recovery efforts continue.

While there have been no reports of injured or affected wildlife from the incident, the City of Philadelphia has advised area residents to drink bottled water "out of caution" as the contamination occurred along a Delaware River tributary in Bristol Township, Bucks County, which provides water to more than 2 million people in Philadelphia, Montgomery, Delaware and Bucks counties. The Philadelphia Water Department is conducting testing to understand potential impacts to the public, though early indications have not revealed contamination.
