Research
 

Dwyer ResearchResearch objectives encompass modeling and understanding the interactions of soil, water, and plants and restoring converted or degraded sites to native habitat with sustainable design as a remediation goal. Current projects include:

The modeling and design of treatment wetlands to remove chemical contaminants, such as arsenic and other heavy metals, from water and soil.

The design of alternative landfill covers that rely on evapotranspiration to control leachate formation in older landfills such as those that are prevalent in Northwest Ohio.

The characterization of hydrodynamic, meteorlogical, and watershed variables in the fate and transport of bacterial and viral pathogens at the public swimming beaches of Maumee Bay for the development of a passive biological treatment system.
