WFAE Contractors for Charlotte Water remove asbestos-laden soil from Sloan Street in Davidson during a water main upgrade project in January. The Environmental Protection Agency will be back in Davidson next week to start another round of asbestos cleanups, including a town park. The EPA tested 136 properties on the town's historically African American West Side last summer and fall and found unsafe levels of asbestos at 11. The asbestos came from an old mill nearby that made asbestos from 1930 to about 1970. Officials say waste asbestos was used as fill in yards and driveways and in the town's Roosevelt Wilson Park. It's a concern because if asbestos fibers become airborne and are inhaled, they can cause cancer and other lung diseases.
