An Environmental And Hydrogeological Investigation In The South Hebgen Basin, Montana, Joe Schmechel

Graduate Theses & Non-Theses

This study was conducted to develop a hydrogeologic framework, and address water quality concerns in the South Hebgen Basin, near the town of West Yellowstone, Montana. The main goals of this research were to: (1) Develop a conceptual model of groundwater flow within the confined aquifer. (2) Use naturally occurring chemical tracers to investigate the confined aquifer’s extent and the connectivity. (3) Identify the influence of geothermal features on water chemistry. (4) Identify water quality issues related to arsenic (As) and fluoride (F-). Long-term static water elevation plots and surface water flow, combined with water ion chemistry were …
