Chemical leak in Goose Creek kills thousands of fish, sparks environmental probe

A chemical leak into Goose Creek in West Chester, Pennsylvania, has caused a major fish kill. The Pennsylvania Department of Environmental Protection (DEP) responded after reports of a milky substance in the water on Saturday. Officials have since warned the public to avoid the creek until further notice.

The DEP traced the leak back to a pipe at Atmos Technologies, a company specialising in odour control and foam solutions for landfills. The substance was identified as a mix of chlorinated water and 'Long Duration Foam AC-645,' which escaped into the creek. The leak was stopped on Saturday after the pipe was sealed.

The creek appeared clearer by Sunday and Monday, though traces of foam remained. Environmental officials are now investigating the exact nature and volume of the release, as well as the steps needed to protect public health. Meanwhile, the Pennsylvania Fish and Boat Commission has increased monitoring, using probes to track water quality and conducting weekly biological checks.

Michael Dunn, president of the Goose Creek Alliance, has called for full transparency and thorough remediation efforts. The incident has raised concerns about long-term environmental impact, particularly after thousands of fish died in a similar leak earlier this year.

Authorities continue to monitor Goose Creek, with ongoing water quality tests and fish population surveys. The public is still advised to keep people and pets away from the affected area. The DEP's investigation will determine further actions to prevent future contamination.
