Groundwater & sludge
Groundwater treatment & sludge upcycling
Connect arsenic removal from drinking water with the recovery of arsenic and phosphorus from treatment residuals.

Research areas and projects
We study groundwater treatment residuals, mining wastes, contaminated soils, and incinerator ash. Each material presents different questions about contaminant speciation, release, and recovery.
Mining pollution
Arsenic-rich mining & processing wastes
Investigate arsenic-bearing mining and processing wastes and develop pathways toward recovered materials.

Soil contamination
Contaminated soils & remediation
Understand how soil chemistry controls contaminant retention, mobility, and the potential for extraction and recovery.

Incinerator ash
Element behavior & ash valorization
Link antimony and phosphorus speciation with leaching behavior and opportunities for recovery from ash.

Phosphate recovery
Phosphorus recovery connects the groundwater-sludge and incinerator-ash research areas. We investigate how to recover useful phosphate products while limiting contaminant co-uptake.
