The soil cleanup is complete and is inspected quarterly to ensure that the grout, left in place from the in situ stabilization, has not been disturbed and the soil cover remains in place. EPA is working with the cleanup party to finalize institutional controls on the upland portion of the site since some contamination was left in place.
