After further testing, the City of Oklahoma City said its water remains safe to drink.
The city came to the conclusion after it conducted water quality testing from 55 sites in areas of the city that were affected by this week's lowered water pressure and service interruptions.
The city's utilities department also said it voluntarily performed bacteriological testing in those same areas.
Its voluntary water boil advisory remains in place for customers affected by low pressure and service interruptions.
The boil advisory is set to expire at 10 p.m. Sunday.
