EPA Begins Review of Ottawa Township Flat Glass Site Naplate, Illinois The U.S. Environmental Protection Agency is conducting a five-year review of the Ottawa Township Flat Glass site located along the north side of the Illinois River in Naplate and the south side of the Illinois River in the City of South Ottawa, Illinois. The site is not listed on the National Priorities List but is an NPL-caliber site addressed through the Superfund Alternative Approach. The Superfund law requires regular checkups of sites that have been cleaned up - with waste managed on-site - to make sure the cleanup continues to protect people and the environment. This is the third five-year review of two operable units of the site. To date, EPA's cleanup actions at the site include arsenic-contaminated soil removal and replacement with clean soil in residential lots in Naplate; no action related to the sediment along the Illinois River; institutional controls to prevent future residential development and drinking water well installation in the affected aquifer; implementation of surface flow and infiltration reduction measures; extension of the municipal water supply to properties with impacted private water wells; and groundwater monitoring. More information is available at the Reddick Public Library, 1010 Canal St., Ottawa, and at www.epa.gov/superfund/ottawa-township. The review should be completed by September 2023. The five-year review is an opportunity for you to tell EPA about site conditions and any concerns you have.
