Progress Update, Week of November 6th, 2023

During the week of November 6, the Gowanus Remediation Team (GRT) continued the RTA 1 Capping Operation.

This week the armor layer placement work began. The GRT began placing concrete mattresses along the bed of the canal to secure the newly placed capping material. Mattresses were placed north of Union Street. Divers were utilized to visually monitor underwater conditions.

Sealant was placed at the Butler Street and Douglass Street bulkheads.
