3. Data Interpretation: Oil thickness1 2 3
Oil level drops with time.
Oil thickness decreases near spill source with time.

4. Data Interpretation: Oil concentrations1 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.)
