CHARLESTON, W.Va. (AP) — A chemical that spilled in the Elk River earlier this month is no longer detectable at five schools.
Water sample test results released last week showed crude MCHM was present at Andrew Heights Elementary, George Washington High School and John Adams Middle School in Kanawha County, Buffalo High School in Putnam County, H.E. White Elementary in Clay County and Lincoln County High School.
The West Virginia Department of Education says the schools were re-flushed and re-tested over the weekend. Samples taken at the three Kanawha County schools, Buffalo High and H.E. White now fall below 10 parts per billion. That's far below the 1 part per million screening level recommended by the Centers for Disease Control and Prevention.
The department is still awaiting more results for Lincoln County High School.
