CARD: Coalition for Action on Remediation of Dioxane

Welcome To The CARD Site

The Coalition for Action on Remediation of Dioxane (CARD) is a partnership of local governments and citizens that develops policies and strategies to address the groundwater contamination from the industrial solvent 1,4-dioxane, released by Gelman Sciences, now Pall Life Sciences (PLS).  The groundwater contamination has expanded in Washtenaw County to an area over three miles long and one mile wide.  The remediation of this site is likely to take an additional 20 years or more based on Pall Corporation and the Michigan Department of Environmental Quality (MDEQ) estimates.
