Investigations into the contamination of the drinking water supply near Pavillion, Wyoming, commenced nearly a decade ago after some changes were noticed by rural residents in the composition of the water in terms of its color, taste, and smell. Since that time, the causation of this water contamination and its possible connection to hydraulic fracturing specifically, and oil and gas development generally, have been hotly debated.

The Pavillion investigation by federal and state authorities has attracted substantial attention because of its focus on the possibility of hydraulic fracturing itself directly leading to the contamination of underground freshwater aquifers.
