The all clear was given for some classrooms at Huckleberry Hill Elementary School in Brookfield, which were professionally cleaned over the weekend after mold was found. New Milford-based Powers Environmental re-tested air quality in the room where a teacher found the fungi under a chair and a common mold that can cause allergy-like symptoms was found. At least half a dozen rooms were cleaned. There were no complaints of coughing and sneezing.
