Surface Water/Groundwater Interactions And Hydrogeochemical Characterization Of The Elkhorn Mine And Mill, Beaverhead County, Montana, Tyler Kamp

Graduate Theses & Non-Theses

The formation of acid mine drainage (AMD) and the contaminants associated with it have been described by some as the largest environmental problem facing the U.S. mining industry. Heavy metals associated with the drainage, such as copper, cadmium, and zinc affect the water quality of streams and can cause acute or chronic toxicity to invertebrates and fish (Martin, 1992& Padrillah et al., 2018). Elkhorn Creek in the Pioneer Mountains of southwest Montana is one of these impacted creeks. The historic Elkhorn Mine and Mill complex has historically attributed to the creek’s contamination and has undergone remediation. However, the problem has …

Determining Groundwater Sources And Ages Via Isotope Geochemistry In Big Sky, Montana, Thomson Connie

Graduate Theses & Non-Theses

The Big Sky ski resort area in southwestern Montana is experiencing exponential growth in both development and population. Concerns have arisen over the quantity of good-quality groundwater in the region, and whether there is a large enough reserve to support the growing demand. In light of already-documented water-level decreases, and domestic wells needing to be deepened or replaced, the Montana Department of Natural Resources and Conservation (DNRC) enlisted the Montana Bureau of Mines and Geology's Ground Water Investigation Program to perform an assessment of groundwater availability and quality in the region, and define groundwater supply sources.

The geology in the …

The Groundwater Of The Area North Of Flathead Lake, Montana, Frederick M. Hilpert

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the reasons for the ground water variations in the area north of Flathead Lake, Montana. Several methods were used in pursuing this investigation. Hydrographs were made of the various wells showing the season to season change as well as the year to year variation.
