The state Department of Environmental Protection is yet to identify a substance that created waves of white foam after being agitated at the York City Wastewater Treatment Plant.

York City on Wednesday notified the DEP after the foam was discovered. The substance did not originate at the plant, and no dead or distressed aquatic life has been found, city officials said.

"A substance appears to have entered the plant through the sewer collection system," Philip Given, the city's acting director of economic and community development, posted on Facebook on Wednesday. "It appears to be a type of surfactant which foams when agitated. The water passed through the treatment plant and was discharged into the creek. Samples were taken to identify the substance and possible source."

When reached on Thursday, DEP spokesman John Repetz said the unknown substance is still being tested and the source remains unknown.

The flow of the substance appears to have subsided, Repetz added.

City officials have declined to comment further.
