Environmental pollution is a major threat to our planet, and water supplies are particularly vulnerable.
Electric utilities, oil refineries, and chemical plants produce billions of gallons of contaminated wastewater each year. In agriculture, toxic levels of various elements pollute the groundwater as a result of excessive fertilizer application, including nitrates and phosphates, and through leaching of naturally occurring trace elements in the soil after irrigation such as selenium. Pollution of both water and soil poses a significant hazard to human health.
Norman Terry and his team are using phytoremediation, a cost-effective and environmentally friendly approach, to clean up contaminated water.
