Research provides a basic understanding of the biologic, chemical, and hydrologic processes that affect partitioning into various environmental media (e.g. water, sediment and tissue) and chemical and microbial transformation. These processes can have a significant effect on the potential toxicity of a contaminant.

Emerging Chemical Contaminants

• Biodegradation of Emerging Contaminants
• In-Stream Processes
• Potential Removal by Wastewater and Drinking Water Treatment
• Swine Waste
• Transport Through the Unsaturated Zone
• Antibiotics in Spring Flush
• Biotransformation of Tributyltin in Freshwater River-Bed Sediments

Emerging Microbial Contaminants

• Swine Waste
