A boil-water advisory in effect since Tuesday in parts of Montgomery County has been lifted.
Pennsylvania American Water said at around noon today that customers no longer need to boil water before using it.
Towns that had been affected by the advisory were East Norriton Township, West Norriton Township, Lower Providence Township, Whitpain Township, Worcester Township and Whitemarsh Township. About 18,000 customers had been affected.
Norristown-area customers also don't need to continue conserving water, officials said.
The utility said the advisory was lifted after "acceptable bacteria test results" were obtained.
The advisory was put in place after the Norristown Water Treatment Plant had problems keeping up with demand, leading to a loss of water pressure in the system.
