Renovations are underway at Garfield High School to replace one of its gym floors after tests revealed elevated levels of mercury.

The bleachers in the old gym were removed. Work is now being done to put down a new hard rubber floor.

"We were not prepared for this, and because of the health and safety issue, we were able to utilize some of the money for the remediation and correction,” says Dr. Giovanni Cusmano, with Garfield Public Schools.

The gym will be done before kids come back to school in the fall.

The bleachers are expected to be fully installed by the end of September.
