Gowanus Canal Community Advisory Group Meeting
Tuesday, June 30, 2015
41 1st Street, Brooklyn NY 11231, Mary Star of the Sea, Community Room
Report from Christos Tsiamis, EPA Project Manager for the Gowanus Canal Cleanup
The EPA Pilot Study on the Canal ends on July 1, 2015.
EPA has met with National Grid and its contractors to advance the design for the remediation of the canal cleanup. The EPA has also met with NYC DEP’s Kevin Clark and his team. Both meetings were very productive. Design of the cap along the bottom of the canal and the in situ stabilization study for cleanup, which was applied at the 7th street basin and could be the basis for the rest of the remedy, is proceeding well.
In situ stabilization technology will keep the contaminants below the cap from de-stabilizing and overwhelming the cap that EPA will place along the bottom of the canal. The technology will help to prevent recontamination of canal waters from toxins leeching up from the sediment below. The technology must be studied before it is applied canal-wide, as it is not yet tested in these conditions and the correct concrete mixture must be identified. The in situ stabilization pilot effort has been very successful, and represents the first cleanup action for this part of the canal. The project is finishing on time.
