Site Updates

May 2011

EPA completed the fourth five year review of the Wausau Ground Water Contamination Site in April 2010. The Superfund law requires checkups every five years of sites that have been cleaned up with waste still managed on-site. Based on the five-year review, EPA recommends evaluating controls put in place for ground water such as ground water monitoring systems and an extraction well. The pumping rate at the well is declining and EPA requests a workplan to address this decline. The soil portion of the site cleanup is complete and monitoring and maintenance plans must be finalized. The next scheduled review ill be in 2015.
