In Washtenaw County and Ann Arbor, Michigan a 1, 4-Dioxane, in groundwater and surface soil contamination from Gelman Science, persists after nearly 20 years of cleanup activities and has now spread in groundwater to an area over three miles long and a mile wide.
The mountain is a giant, putrid layer-cake, with dozens of strata of rubbish separated by soil and plastic liners designed to contain the brew of noxious chemicals that would otherwise leach into groundwater.
