Action Taken

In 2016, the Army Corps of Engineers, on behalf of the U.S. EPA, completed the second Five Year Review (FYR). The FYR concluded that while the remedies are still protective of groundwater, indoor air near where soil was contaminated will need to be re-evaluated.

In April 2017, the U.S. EPA released a fact sheet explaining what vapor intrusion is, how it is determined if vapor intrusion is a concern, and the areas to be re-evaluated.


Vapor intrusion work is currently underway at the NIBW Superfund Site, lead by the U.S. EPA. For more information on vapor intrusion, please contact the U.S. EPA.

An amended FYR will be released after the vapor intrusion work has been completed and evaluated.
