Shallow Groundwater Quality And Geochemistry In The Shields River Basin, South-Central Montana, Daniel D. Blythe
Shallow Groundwater Quality And Geochemistry In The Shields River Basin, South-Central Montana, Daniel D. Blythe
Graduate Theses & Non-Theses
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. Water samples from surface water sites were collected in October to characterize base flow conditions. Physical characteristics of the land …
Geochemical Assessment And Separation Of Source Waters In The Upper Boulder River Watershed Near Boulder, Mt, John Anderson
Geochemical Assessment And Separation Of Source Waters In The Upper Boulder River Watershed Near Boulder, Mt, John Anderson
Graduate Theses & Non-Theses
Environmental samples were collected at three surface water sites between 5/21/2011 and 11/21/2014 along the Upper Boulder River near Boulder Montana. The sites were located at Bernice (within the mountain block), near the High Ore drainage (near the mountain block/basin transition), and at the USGS Gauging Station near Boulder, Montana (within the basin). The parameters measured in the field were SC, temperature, and alkalinity with occasional pH measurements. We collected samples for anions, cations, and stable isotopes in the catchment. We identified endmembers by sampling snow and groundwater and determined from available data an approximate endmember for rain, snow, and …
Biogeochemical Cycling In A Headwater Stream And Riparian Zone, A. Capri Gillam
Biogeochemical Cycling In A Headwater Stream And Riparian Zone, A. Capri Gillam
Graduate Theses & Non-Theses
Several teams of researchers at multiple universities are currently measuring annual and seasonal fluxes of carbon dioxide and other greenhouses gases (nitrous oxide and methane) in riparian wetlands and upland forests in the Tenderfoot Creek Experimental Forest (TCEF), a subalpine watershed in the Little Belt Mountains, Montana. In the current thesis, the author characterized the geochemistry and stable carbon isotope composition of shallow groundwater, soil water, and stream water in upper Stringer Creek, near sites that are being investigated for gas chemistry and microbial studies. It was hypothesized that if methanogenesis were a dominant process in the riparian wetlands of …
