Remedial Design

Following the release of the EPA Record of Decision in 2013, Arconic (formerly Alcoa) has been conducting a series of investigations in the river in support of the remedial design. These studies included additional sampling and surveys as well as habitat assessment and cultural resources work. Specific information being developed includes identifying the final limits of where remedial work will be conducted and understanding current habitat conditions in support of future habitat restoration work. The development of the remedial design using the information developed from these studies is currently ongoing.

Arconic is constructing land-based facilities to support future in-river remediation work, including a staging area near the Route 131 bridge. This work started in spring 2017 and is expected to be completed in 2018.
