Our research focuses on the application of chemical, biological, and physical principles to the solution of water-quality problems. Recent research has involved problems associated with acid rain, water-quality control for intensive aquaculture, and control of lead and copper in water-supply distribution systems. Our research on acid rain has primarily involved manipulation of the pH-buffering system to control lake acidification. Specifically, we are studying carbon dioxide equilibrium and kintetics as they relate to lake pH. Our work on the control of water quality for aquaculture involves evaluation of the changes in water chemistry that occur in intensive (self-contained) aquaculture systems. Water-quality parameters studies include pH, suspended solids, and surfactants. We have used laboratory-scale pipe loops to evaluate the chemical nature of lead and copper in drinking-water distribution systems. Results of this study are being used to select chemical methods that will reduce lead and copper to acceptable levels. Current related Research focuses on characterization of the physical/chemical nature of lead in drinking-water systems.
