Paul Buszka

Paul is a Supervisory Hydrologist in the Hydrologic Investigations Section. Paul began his career at USGS as a Hydrologist in San Antonio, Texas (1984) and has since worked in Austin, Texas (1986-1993) and Indianapolis, Indiana on a variety of groundwater and water chemistry studies. He also worked as a Hydrogeologist with STS Consultants in Green Bay, Wisconsin (1982-84). 


As a supervisory hydrologist, Paul works with a diverse scientific staff in Indianapolis and Louisville and USGS partners to identify, facilitate and pursue scientific investigations intended to increase understanding of the quantity, quality and availability of groundwater and surface water in Indiana, Kentucky, and the Nation.  Topics of these investigations by Hydrologic Investigations Section and collaborating scientists in recent years have included:

  • Application of water well records to understand the distribution of groundwater in the glaciated USA
  • Groundwater-surface water interactions and their relation to wetland restoration
  • Wastewater compounds in surface water from a restored wetland and in Lake Michigan tributaries
  • Groundwater flow simulations to understand relation of local and subregional groundwater flow at a closed coal mine
  • Application of groundwater age dating and stable isotopes to understand aquifer recharge relative to potential constituent sources 
  • Laboratory performance of borehole flowmeters in controlled flow settings
  • Application of aquifer tests to understand changes in well performance and aqufier characteristics
  • Laboratory and field evaluations of water quality effects and potential treatment benefits from steelmaking slags
  • Continuous monitoring of carbon dioxide in water

Cooperative relationships with numerous Federal, State, local and private partners were established or renewed during my term.  

My projects at USGS have covered a wide range of interests including

  • Integration of hydrophone telemetry with USGS streamflow gage assets to detect Asian Carp
  • Geochemical aspects of carbon dioxide at a potential invasive species barrier site in Illinois 
  • Groundwater hydrology and quality of carbonate aquifers and alluvial deposits,
  • Boron isotope geochemistry and contaminant source evaluation
  • Environmental fate and tracer applications of volatile organic, wastewater and pharmaceutical compounds,
  • Applications of elemental ratios to evaluate oil and gas brine and salinity sources, and
  • Groundwater-age estimates using tritium and fluorocarbon tracers. 


Attended Michigan State University, East Lansing, Michigan (B.S., Geology, 1979) and University of Waterloo, Waterloo, Ontario, Canada, M.Sc., Hydrogeology and Environmental Geochemistry, 1982. M.Sc. research centered around fate and transport of leachate contaminants from a landfill in a terrain that was depleted in carbonate minerals.
