Officials initially believed the green glow was caused by an antifreeze spill, WHP reported.

The state Department of Environmental Protection determined the green color was caused by a green food dye spill, according to the Manor Township Police Department.

“There is no concern for impact to the public or any drinking water. As well, there is no impact to wildlife that has been noted,” the HazMat 2 Environmental Fire Rescue Company said.

Peter Taraborelli of Mountville Fire Company told WGAL that the green dye was traced to a retention pond.

Manor Township is about 80 miles west of Philadelphia.
