The Pittsburgh Water and Sewer Authority inadvertently released about 400 gallons of a food-grade citric acid mix into its water distribution system Tuesday but said it's received no complaints.

The release occurred about 12:30 p.m. at the micro-filtration plant in Highland Park. The chemical is used to clean filters.

The authority said it notified the Allegheny County Health Department and the city's emergency-management office and began taking steps to flush the chemical from the system.

The authority's chemists monitored pH levels but had detected no problems, according to a statement from the authority.

Though the chemical can produce a sour taste and skin irritation, no complaints have been reported, spokeswoman Melissa Rubin said. If residents encounter problems, the authority encourages them to call dispatch at 412-255-2429 or 412-255-2409.
