Thousands of gallons of chemicals were spilled into the Delaware river following a spill from a factory outside Philadelphia. The chemical plant owned by Trinseo estimated that 8,100 gallons of a latex finishing solution spilled into Otter Creek which is located about a dozen miles upstream from a drinking water treatment plant. According to Trinsea the spill was due to an equipment failure which is the leading cause of chemical spills according to a 2021 EPA report. One of the chemicals found in the solution is butyl acrylate which can cause skin irritation, headaches, dizziness, and vomiting.
