[email protected]. Shallow Groundwater Quality and Geochemistry in the Shields River Basin, South-Central Montana by Daniel D. Blythe A non-thesis project report submitted in partial fulfillment of the requirements for the degree of Master’s in Geoscience: Hydrogeology Montana Tech of The University of Montana 2015 ii Abstract Water samples were collected from 33 domestic wells, 2 springs, and 3 streams in the Shields River Basin (Basin) in southwest Montana. Samples were collected in 2013 to describe the chemical quality of groundwater in the Basin. Sampling was done to assess potential impacts to water quality from recent exploratory oil and gas drilling and to establish baseline water quality conditions. Wells were selected in areas near and away from oil and gas drilling and in areas susceptible to contamination.
