Walter Illman

Walter Illman specializes in groundwater hydrology, both in the saturated and unsaturated zones.

He uses mathematical modeling, laboratory and field experiments to understand contaminant transport and natural degradation of organic contaminants in groundwater.

• Mathematical modeling (analytical and numerical) of fluid flow and contaminant transport in groundwater
• Laboratory and field experiments on contaminant transport in porous and fractured geologic media
• Behaviour of contaminants in groundwater, such as Dense Non Aqueous Phase Liquids (DNAPL), bioremediation and natural attenuation of organic contaminants
• Threats to Aquatic Ecosystems and their Interaction
• Contamination & Remediation: Water, Soil, Air
• Carbon Dioxide Capture and Storage
• Geohazards: Risks and Prevention
• Climate Change and Geosciences
• Renewable Energy
• Increasingly Complex Water Challenges
• Protection of Surface and Groundwater Resources
• Sustainable Water Use and Management
• Legacies of Agriculture Pollutants
• Water Security in Mega Cities
• Protection of Drinking Water from the Ravages of Climate Change
