Current  Interests: Ground-water exchange has significant effects on the physical hydrology, chemistry, and ecology of lake, river, and wetland systems. An improved understanding of their connections and exchanges can improve water resources management and policy. Below are some of the research topics I am currently involved with. We are always looking for interested students that don't mind getting their feet wet!  If you are interested please contact me at: odriscollm@ecu.edu . A more detailed summary of past and recent works can be found here: C.V.   

                                 

• Effects of urbanization on river-groundwater interactions in the Coastal Plain of North Carolina.                                          

• Characterization of surface water-groundwater interactions along the Tar River. 

• Geological controls on septic system treatment of wastewater in Coastal NC. 

• Field methods to investigate nourishment of wetlands and wastewater migration in the subsurface.      

• Nutrient processing in Appalachian headwater catchments.
