James W Roy

James W Roy is an Adjunct Associate Professor in the Department of Earth, Environment & Society at McMaster University. His research focuses on groundwater-surface water interactions, contaminant transport, and ecological impacts of urban and industrial groundwater plumes. He employs advanced geophysical techniques (e.g., DC-IP imaging) and chemical tracers (e.g., artificial sweeteners) to study hydrological processes in alpine, agricultural, and urban stream systems.

Key research areas include:

• Groundwater contamination by PFAS, road salts, and septic systems
• Aquatic ecosystem exposure to chloride and nutrient plumes
• Biogeochemical cycling of phosphorus, nitrogen, and carbon
• Hydrological modeling of glacial moraine and riparian zones

Recent publications (2023-2025) emphasize freshwater salinization, toxicity assessments, and long-term groundwater monitoring. No formal awards or student advisories are documented in the provided materials.
