The purpose of this study was to examine the hypothesis that groundwater and surface water interaction resulted in the development a 1,4-dioxane plume in a glacial aquifer in Scio Township, Washtenaw County, Michigan.

An industrial solvent, 1,4-dioxane, was detected in the groundwater in the area of study in 1986. This area, referred to in this investigation as the Western Plume, is one of several 1,4-dioxane plumes associated with the Pall/Gelman Sciences Inc. (P/GSI) site, an extensively investigated site of groundwater contamination.

1,4-Dioxane in the Western Plume area was initially believed to be the result of contaminated groundwater transported from a main plume area closer to the P/GSI facility. As additional hydrologic and hydrogeologic data were collected in the Western Plume area, it became apparent that a segment of a surface water body, a tributary to Honey Creek (HC) identified as Sisters Lake Drain (SLD), and a small inland lake (Little Lake) were likely losing water bodies and therefore had the potential to be a source of 1, 4-dioxane to the Western Plume area.

The role of groundwater and surface water interaction in the development of groundwater contamination in the study area was investigated by examining: (a) source availability; (b) the hydrologic and hydrogeologic conditions in the study area, and (c) the spatial and temporal distribution of 1,4-dioxane in surface and groundwater.

This study concludes that the source of 1,4-dioxane in the Western Plume area was groundwater and surface water interaction along a portion of the SLD and Little Lake.
