Because of what it called a "vague threat," the Altoona Water Authority is recommending that public water customers in the greater Hollidaysburg area not drink or otherwise consume tap water for 48 hours, beginning around 7 p.m. Friday.
An advisory on the Altoona Water Authority website states that people in the affected areas should use an alternate water source or bottled water "for drinking, making ice, brushing teeth, washing dishes and food preparation until further notice."
The recommendation applies to customers of the Hollidaysburg Borough, East Freedom and Blair Township water systems and to customers of the Altoona Water Authority in the Foot of Ten and William Penn Highway (Route 22) areas, according to authority General Manager Mark Perry.
The advisory does not affected Duncansville Borough water customers.
The authority has done normal tests on finished water that could have been affected and found no clear sign of contamination, according to Perry.
The state Department of Environmental Resources has taken samples, which will require a wait time of 24 to 48 hours for results, according to Perry.
