"They got there [Grandview] and could smell a low odor," he said. "We investigate first, then decide if it's appropriate to send students home."
There are still no plans to conduct air tests in addition to water tests, despite complaints about burning eyes, fainting and other symptoms that could be related to inhaling the water's fumes.
DEP spokesman Tom Aluise said that inspectors from the agency's Division of Air Quality are part of the school response team, but that the DEP's role "isn't real involved."
"They don't do any air sampling," Aluise said. "Because they take smell sensitivity training as part of their normal training to be DAQ inspectors, the response team thought it would be beneficial to have them on hand to help detect odors or to rule out other potential sources of odors."
Earlier this month, odor complaints were reported at Riverside High School and Midland Trail Elementary on a Monday after students and teachers reported back to school following the weekend break.
Whether that time off over the weekend with no faucets running creates an abnormally strong odor once faucets are turned on on Monday is unknown, Hollandsworth said.
"I would be guessing," he said. "I don't know."
The school system is not regularly flushing faucets while students are out of class, and only re-flush schools where complaints are made, Hollandsworth said.
