Irene J Fisher


Irene began her career with the USGS as a Volunteer for Science. She held a student trainee position while attending college and was hired shortly after graduation as a hydrologist. Research interests include groundwater quality, nitrogen cycling, and coastal and estuarine systems. Irene currently manages water-quality projects in Long Island, N.Y., with a special interest in contaminants of emerging concern. Current programs include the occurrence and persistence of wastewater-derived contaminants, current and legacy-use pesticides, and per- and polyfluoroaklyl substances (PFAS) in groundwater. Her research interests and capabilities have led her to work with other USGS scientists on diverse project work including isotope forensics, groundwater age dating, stream-quality assessments, environmental health impacts of Hurricane Sandy, and National Water-Quality Assessment (NAWQA) programs.
