CHARLESTON, W.Va. -- Rapid response teams were dispatched Monday to investigate water odor complaints at three local schools, though none of them had to be closed.
Officials investigated complaints at Riverside High, Midland Trail Elementary and Grandview Elementary schools.
Water samples were taken at each even though sources of the odor were not identified.
Lawrence Messina, state Department of Military Affairs and Public Safety spokesman, said there has been some discussion as to whether the odor at Grandview could be attributed to MCHM.
He said some members of the response team believe the school might be experiencing odors due to issues with one of its boilers.
This is not the first time the rapid response team has visited Grandview. The school was closed Feb. 18 after several teachers reported strong, licorice-like smells associated with crude-MCHM, the coal-cleaning agent that leaked into the local water supply in early January.
Test results later in the day showed no sign of the chemical at the 10 parts per billion screening level. Grandview's results from Monday's testing will be available today.
Schools are now being tested at a new, more strict 2-parts-per-billion screening level.
Messina said the response team could not trace an odor at Riverside High, but a water sample was taken just to be safe.
He also said Midland Trail's principal reported an odor but believes it might be unrelated to MCHM.
After testing at Midland Trail, the response team moved on to Boone County to continue conducting tests at the new screening level.
Gov. Earl Ray Tomblin called for further water testing last week to confirm that all schools in the nine affected counties are safe.
Initial results from 90 schools are coming back at non-detect levels at 2 parts per billion.
Before Tomblin issued new screening guidelines, the National Guard tested water at 10 parts per billion, which is 100 times more protective than the U.S. Centers for Disease Control and Prevention's recommended testing level of 1 parts per million.
The new screening level is even more stringent, and is 500 times more protective.
The state Department of Education expects results from the remaining schools in the coming days.
