Do Roane Co. school officials buy the "water is safe" line?

In a news conference today, Roane County School officials said that, although authorities say the water in Roane County is safe to drink despite the massive fly ash sludge spill, school food will be prepared with bottled water, parents and staff are encouraged to bring bottled water to school if they want, and the school system has purchased extra bottled water to sell at school.

This begs the question of whether school officials believe the water really is safe.
