There is a long road ahead to adequately address an expanding 1,4 dioxane plume in the Ann Arbor area. The plume has contaminated wells in Scio township and Ann Arbor and is slowly moving towards the city's municipal water supply at Barton Pond. In this month's '1st Friday Focus on the Environment',  Liza Wozniak talks with Washtenaw County Commissioner Yousef Rabhi about the next steps in the journey.
