Progress Update, Week of October 18, 2021

During the week of October 18, the Gowanus Remediation Team (GRT) began a demonstration of In-Situ Stabilization (ISS). ISS is a remediation process by which contaminants are rendered immobile through reactions with stabilizing compounds mixed directly into the soil or sediment. The demonstration will involve stabilization of a small target area, followed by analysis of the results, and is expected to be completed in Winter 2021.

Sediment removal near the Union Street Bridge will continue over the coming weeks.

The GRT continued preparing for sheet pile bulkheads installation along the west side of the Canal near Degraw Street.

Photos of construction activities are provided below.
