"Gym class has been relocated in eight Washington Township schools as district officials weigh what could be a $3.2 million plan to replace rubber flooring that’s been emitting a mercury vapor into the air.

The school board in Gloucester County will hold a special meeting Wednesday night address concerns about mercury contamination in eight of the township’s 11 schools. The mercury had been used during the installation of rubberized flooring before 2000 and several years thereafter. Deteriorating floors are emitting mercury vapors which can be hazardous, officials said."
