Carol Ptacek

Dr. Carol Ptacek conducts research on a variety of topics in contaminant hydrogeology and geochemistry, including studies on mechanisms controlling the fate and transport of metals, nutrients, pathogens, organic compounds in groundwater.

She leads the Groundwater Geochemistry Remediation Group together with David Blowes.
