Philadelphia tap water safe through Wednesday night after chemical spill in Delaware River.

The city of Philadelphia has extended the deadline for residents to safely use tap water until at least 11:59 p.m. on Wednesday, March 29. The tap water is safe to drink, cook and shower with, according to officials. The city has been monitoring the water quality since a chemical spill of 8,100 and 12,000 gallons of a latex emulsion product made its way into Otter Creek in Bristol, Bucks County, and then into the Delaware River. No contaminants have been detected in the Delaware River water, and no residual plume or contamination of residual water is expected by Wednesday or Thursday.
