wetlands pictureEnvironmental pollution is a major threat to our planet. Pollution of precious water supplies is particularly egregious. 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.

Finding suitable treatment technologies to clean up contaminated water and soil wastewater is not easy. The few technologies that are available are usually prohibitively expensive. Because the need for practical and cost-effective procedures for cleaning up contaminated water and soil is so great, researchers at the Terry lab have dedicated themselves to achieving this goal through phytoremediation, a cost-effective and environment-friendly approach for cleanup. Over the past 18 years, we have had demonstrable success in cleaning up contaminated wastewater and soil. Researchers at the Terry lab have dedicated themselves to cleaning up the environment using phytoremediation, a cost-effective and environment-friendly approach. 


Use of phytoremediation to decontaminate soil

Contaminated sites may be restored using different phytoremediation approaches.

Use of constructed wetlands to decontaminate wastewater

Constructed wetlands are virtually the only means of cleaning up large volumes of water contaminated with very low levels of pollutants, e.g. toxic trace elements.

Role of microbes in phytoremediation

Microbial remediation can be carried out by free-living or rhizosphere (root-associated) microbes. Examples of various types of microbes (including microalgae) used in trace element remediation and hydrocarbon degradation are presented here.
