Riverside and Midland Trail -- which are next to each other in Quincy -- are not the first schools that have had to flush their water systems more than once following a chemical leak into the Elk River last month.
Just last week, Crude MCHM was detected at six area schools -- long after the water ban had been lifted and schools had been cleared by the Health Department to reopen for class.
Over the weekend, those schools were again cleared, after the schools' pipes were re-flushed and a second round of testing showed undetectable levels of the chemical.
Photos of brownish water from Midland Trail's taps circulated on social media, but Kanawha County Schools Superintendent Ron Duerring said the discoloration was not related to the chemical leak.
"The yellow water was from a water line break off our property that had nothing to do with this," Duerring said. "What we're responding to is some kind of odor. I don't know what caused that. I have no idea."
Schools impacted by the chemical leak are continuing to cook only with bottled water, and Riverside High received four more shipments Tuesday.
Harper said at Riverside they're even using bottled water to clean desks and floors, and water fountains and sinks are off limits to students.
"It just takes a bit of an extra step, but we're trying to do the best we can," Harper said. "Honestly, I expected more drama -- more questions. ... It's the most difficult for the cooks. They're the ones that have to prepare the food and use a different routine."
