With classes starting in New Milford next week, recovery work is wrapping up on most of the High School a July roof fire.  About 200,000 square feet was impacted. Over  300,000 ceiling drop tiles have been replaced.  All of the ceiling tiles in the center of the school were taken out because they're porous and were impacted by smoke or water. Air quality testing shows no lingering issues from smoke damage.  Prior to the fire, the district replaced 2-inch filters with 4 inch filters.  Contractors took those out and put in new carbon filters and pleated filters, which Public Works Director Jack Healy says makes for even higher quality filtering.  A number of steps were taken to ensure there wouldn't be any mold from water damage.  Healy says the walls are porous so the only way was to remove them.  The areas were all cleaned, insulation was replaced and the solid duct work was inspected before walls were rebuilt.  Air quality tests show there are no particulates remaining.
