Source Tracing of Toxicants in Storm Drains
Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information,...
Health Effects of Ground Water Recharge
A five year multidisciplinary research project was conducted to evaluate the health significance of using treated wastewater for ground water replenishment. The focus of the study was...
Managing Dioxin
Dioxins, among the most toxic compounds known to man, are by-products from production of other chemical products. There are currently about 5000 metric tons of dioxin-containing wastes...
An Overview of Toxic Emissions and Best Available Control Technology for Municipal Waste Incineration
Effects of Toxic Chemical Perceptions on Fishing Behavior
This study investigates: 1) whether angler's who perceive toxic chemicals in the water fish any differently than those who do not, and 2) do these behavioral differences have...
