  1. Ground water contamination at Bemidji, MN Part 2: Danny Bailey http://www.epa.gov/oilspill/photo.htm

  2. Outline: Danny Bailey • Introduction • Significance • Description of site • Study objectives • Data • Methodology • Data analysis • Data interpretation • Results • Limitations • Future Work http://www.epa.gov/oilspill/photo.htm

  3. Data Interpretation: Oil thickness 1 2 3 • Oil level drops with time. • Oil thickness decreases near spill source with time.

  4. Data Interpretation: Oil concentrations 1 2 3 • No obvious change in Benzene • concentrations with time. • Toluene concentrations increase • with time away from the spill source.

  5. Results

  6. Results: Arc Scene Demo

  7. Limitations • Time • Sorting numerous attribute tables • Projection • Area too small for surface/subsurface water interaction. • Difficulty to link stream network to ground water. • Geological framework • Linking different lithologies across the area. • Interpreting lithological distribution.

  8. Future Work • Create polygons for geological framework. • Investigate porosity and permeability effects on hydrocarbon distribution and migration. • Determining the cause of oil thickness variations (i.e. water table fluctuations, etc.)

  9. Acknowledgments • Gil Strassberg (CRWR) • Dr. David Maidment • Suzanne Pierce (UTDoGS) • Geoff Delin and Todd Anderson • http://mn.water.usgs.gov/bemidji/
