BRIDGEPORT, W.Va. -- The Harrison County Board of Education has hired a contractor to remove mold from an elementary school where air quality concerns prompted the relocation of three classrooms. Media outlets say the board voted Tuesday during an emergency meeting to pay Basement Systems of West Virginia more than $168,000. The work is expected to take five to six weeks. Air quality tests at Johnson Elementary School in Bridgeport found elevated levels of mold in three classrooms. Two classrooms have been temporarily moved to Bridgeport High School. The third classroom was relocated to a modular unit at the elementary school.
