CHARLESTON, W.Va. — Crude MCHM was not detectable in tap water at five West Virginia schools following additional flushing this weekend, according to information from the state Division of Homeland Security and Emergency Management.
Those schools were George Washington High School, John Adams Middle School and Andrews Heights Elementary School in Kanawha County; Buffalo High School in Putnam County and H.E. White Elementary School in Clay County.
As of Sunday afternoon, results from another round of testing had not been returned for Lincoln County High School, a sixth school where tests showed detectable levels of crude MCHM during testing last week.
During the testing, all of the schools came in well below the one part per million the Centers for Disease Control considers “safe” for MCHM in tap water. However, the extra school flushing started, at the identified locations, because the chemical levels at those six schools were still above the ten parts per billion “non-detect” levels.
In all, tap water has been tested at more than 100 schools in the nine-county region that was under a do-not-use water order from West Virginia American Water Company following a Jan. 9 leak of MCHM and PPH along the Elk River.
By Sunday, almost all of those schools were at “non-detect” levels.
In addition to Lincoln County High School, tests results were still pending Sunday for the Charleston Montessori School in Kanawha County and Yeager Career Center in Lincoln County.
