BURLINGTON, Vt. (AP) — The Environmental Protection Agency says low levels of two potentially dangerous chemicals were found in an elementary school in Burlington, Vermont.

WCAX-TV reports tests determined levels of perchloroethylene and trichloroethylene at Integrated Arts Academy don't pose a threat. The EPA tested gas underneath the school and air in the building.

The chemicals in question are carcinogens that historically have been used by dry cleaning operations in an area where the dry cleaner store closed nearly 30 years ago.

Vermont Department of Health toxicologist Sarah Vose says the chemicals are below the level that would harm people. Vose says the chemicals can be removed from the air by a depressurization system.

Burlington Schools Superintendent Yaw Obeng says the district will work with state environmental officials to fix the issue.
