PWD Monitoring Non-Hazardous Green Tracing Dye Spill in Montco
The Philadelphia Water Dept. is monitoring a spill of a non-hazardous green tracing dye in a Montgomery Co. tributary of Tacony Creek that was reported to the Pa. Dept. of Environmental Protection this morning, Friday, March 24, 2023.
PWD reported the incident to the Delaware Valley Early Warning System to alert water users in the Delaware River.
We will continue to track the dye, but do not believe it will impact drinking water intakes at this time.
The dye is a common product used to determine the source of water leaks and is not a threat to health. Approximately 0.5 pounds were spilled near Baeder Creek in Jenkintown Township. Rain and river currents are expected to flush the dye from the area within the next 24-48 hours.
This post will be updated with any additional information. To get alerts about drinking water quality, sign up for Ready Philly notifications.
