Unknown, Toxic 'Milky White' Substance Leaks Into Chester Co. Creek

WEST CHESTER, PA — A unidentified "milky white" substance from an industrial site has leaked into Goose Creek in West Goshen and West Chester, killing fish and causing significant environmental harm, authorities said Monday afternoon.

The substance was first spotted at around noon on Saturday, Feb. 28 on Nields Street.

The substance was then quickly traced to a nearby industrial site, located near Henderson High School. Authorities have not yet publicly identified the specific facility responsible for the discharge.

Tests are underway to determine the nature of the substance, which has proven environmentally toxic. Residents are urged to avoid Goose Creek until further notice.

West Chester officials said that the "source of the illicit discharge" was found and quickly plugged on Saturday. However, the damage to the creek was done.

"As part of the cleanup and remediation process, the business will be subjected to rules and regulations of PADEP and West Goshen Township, and could face fines," West Chester said in a statement Monday.

Authorities remain on scene attempting to determine exactly what was released, and how much of it.

State Sen. Carolyn Commita said that investigators would determine "what steps need to be taken to protect public health."

Chester County's Hazardous Materials Response Team, along with the Pennsylvania Department of Environmental Protection and the PA Fish and Boat Commission, have all been mobilized to the scene.
