Columbia Borough School District was closed Friday while the state continued testing the community water supply for possible contaminants.
A "Do Not Consume" order issued to about 8,700 customers after a break-in at a water plant overnight Wednesday remains in effect.
The school was closed as a precaution, said Jeff Helm, health officer and zoning and planning officer for the borough.
Helm said he advised school district Superintendent Barry Clippinger Thursday night that water fountains would be off limits and food workers would have to use bottled water if the schools stayed open.
"Hand washing at this point," Helm added, "it's all questionable."
Helm said Friday morning that the state Department of Environmental Protection was checking for a wide array of potential foreign substances.
