Masters Theses

Groundwater contamination has occurred in the vicinity of the Dowagiac landfill, Dowagiac, Michigan. The groundwater has been degraded by the presence of organic hydrocarbons, trichloroethylene in particular. At least two aquifers are thought to be present in the area with the upper unconfined aquifer being contaminated while a lower confined aquifer remains uncontaminated. This lower aquifer is thought to be protected from above by a clay layer. A combined geophysical survey consisting of seismic refraction and electrical resistivity surveys was conducted to determine the continuity and thickness of this clay layer as well as the extent of the contamination. A …
