2023 Delaware River chemical spill

The 2023 Delaware River chemical spill was a failure of equipment that occurred on March 24, 2023 at the Trinseo Altuglas chemical plant in Bristol, Pennsylvania in the United States, which resulted in a leak of between 8,100 and 12,000 gallons of butyl acetate, ethyl acetate, and methyl methacrylate into Otter Creek, a tributary of the Delaware River.

[1][2] During the aftermath, multiple members of the news media drew comparisons to the 2023 East Palestine train derailment because one of the chemicals spilled, butyl acetate, occurred in both incidents.

[17] Many nearby counties in southeastern Pennsylvania, as well as in western New Jersey also began testing their water supply as a precaution.

[18] Officials from the Pennsylvania Department of Environmental Protection[19] stated that there had not been any discernable effect on the fish and wildlife of the area.

The EPA, NOAA, PDEP, and PFBC also visited the site to monitor for ecological damage and health risks.

[5][30][17] American conservationist Gary Belan subsequently released a statement in which he demanded that further attention be given to the spill, and that any adverse effects caused by the contamination by rectified by Trinseo.
