Timothy T Bartos
Tim has been a hydrologist with the USGS in Cheyenne, Wyoming, beginning as a student in 1990. He was the National Water Quality Assessment (NAWQA) Yellowstone River Basin Groundwater Specialist from 1997 to 2007. In 2002, Tim was named the Groundwater Specialist for Wyoming, and in 2012 was assigned to be the Groundwater Specialist for Montana as well.
Tim has investigated a wide variety of local (site-specific) and regional (basin or larger) scale groundwater studies. These studies have included both the physical and chemical aspects of hydrogeology, with many integrating both aspects. Detailed characterization of groundwater systems at various scales through the utilization and integration of physical (for example, detailed geologic/lithologic/stratigraphic examination and borehole geophysics) and chemical methods (groundwater chemistry) is of particular interest to Tim.
Tim is recognized for his knowledge of Wyoming’s hydrogeology, and is a licensed Professional Geologist in the state (PG-3349).

Quality of Shallow Ground Water in Three Areas of Unsewered Low-Density Development in Wyoming and Montana, 2001
The quality of shallow ground water underlying unsewered low-density development outside of Sheridan and Lander, Wyo., and Red Lodge, Mont., was evaluated. In 2001, 29 wells (10 each in Sheridan and Lander and 9 in Red Lodge) were installed at or near the water table and sampled for a wide variety of constituents to identify potential effects of human activities on shallow ground-water quality res

Infiltration from an impoundment for coal‐bed natural gas, Powder River Basin, Wyoming: Evolution of water and sediment chemistry
Development of coal‐bed natural gas (CBNG) in the Powder River Basin, Wyoming, has increased substantially in recent years. Among environmental concerns associated with this development is the fate of groundwater removed with the gas. A preferred water‐management option is storage in surface impoundments. As of January 2007, permits for more than 4000 impoundments had been issued within Wyoming. A

Estimated water use in Wyoming during 2000
The U.S. Geological Survey (USGS) has compiled and published estimates of water withdrawals every 5 years since 1950. This series of water-use reports serves as one of the few sources of information about regional or national trends in water withdrawals (Hutson and others, 2004).In Wyoming, six categories—irrigation, mining, thermoelectric power, public supply, self-supplied domestic, and industri

Water resources of Carbon County, Wyoming
Carbon County is located in the south-central part of Wyoming and is the third largest county in the State. A study to describe the physical and chemical characteristics of surface-water and ground-water resources in Carbon County was conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer's Office. Evaluations of streamflow and stream-water quality were limited to a

Water quality in the Yellowstone River Basin, Wyoming, Montana, and North Dakota, 1999-2001
This report contains the major findings of a 1999?2001 assessment of water quality in the Yellowstone River Basin. It is one of a series of reports by the National Water-Quality Assessment (NAWQA) Program that present major findings in 51 major river basins and aquifer systems across the Nation.
In these reports, water quality is discussed in terms of local, State, and regional issues. Conditi

Water-quality characteristics of quaternary unconsolidated-deposit aquifers and lower tertiary aquifers of the Bighorn Basin, Wyoming and Montana, 1999-2001
As part of the Yellowstone River Basin National Water Quality Assessment study, ground-water samples were collected from Quaternary unconsolidated-deposit and lower Tertiary aquifers in the Bighorn Basin of Wyoming and Montana from 1999 to 2001. Samples from 54 wells were analyzed for physical characteristics, major ions, trace elements, nutrients, dissolved organic carbon, radionuclides, pesticid

Water quality and environmental isotopic analyses of ground-water samples collected from the Wasatch and Fort Union Formations in areas of coalbed methane development — Implications to recharge and ground-water flow, eastern Powder River Basin, Wyoming
Chemical analyses of ground-water samples were evaluated as part of an investigation of lower Tertiary aquifers in the eastern Powder River Basin where coalbed methane is being developed. Ground-water samples were collected from two springs discharging from clinker, eight monitoring wells completed in the Wasatch aquifer, and 13 monitoring or coalbed methane production wells completed in coalbed a
