While conducting oversite of the Madison Central School Mercury response, a residential property was assessed for mercury contamination. This residential property was discovered to have high mercury vapor concentrations and the family was relocated. EPA's ERRS contractor was tasked to start cleanup of the residence and EPA's START contractor will provide oversight sampling support. The Corps of Engineers will be asked for assistance in the relocation of the family. OSC Jardine, OSC Tanner and ERT's John Gilbert are responding.
