As a result of the 5-year Review by MDEQ in November 2007, this site was placed in post remediation phase for a period of 20 years beginning in August 2009 through 2029 to continue the degradation process for the remaining groundwater contaminates. Dioxin is no longer listed as a contaminant of concern based on the 2007 MDEQ 5-year Review. The analytical data is presented to the MDEQ on an annual basis.
