Earlier this month, contractors working for the Environmental Protection Agency began work on a dredging and capping pilot study in the Gowanus Canal’s 4th Street Turning Basin.
The process involves installation of steel sheeting in front of existing bulkheads, followed by dredging of contaminated sediment from the canal, before the installation of a multi-layered protective cap at the bottom of the canal.
The EPA expects to complete this pilot effort in the Spring of 2018. The results of the study will be used to evaluate and finalize the elements for the dredging and capping of the entire canal.
