This project is investigating the potential role of constructed and natural wetlands in treating non-point source pollution and evaluating the importance of such wetlands in catalyzing photolysis of herbicides and pharmaceuticals. The research plan is hypothesis-driven and will test the innovative idea that addition of iron to wetlands will promote photolysis of synthetic organic contaminants by generating reactive oxygen species. The target chemicals to be studied include three herbicides and two pharmaceuticals. The results will lead to improved understanding of treating organic contaminants in surface wetlands and benefits could accrue to society if constructed wetlands could be designed to provide better treatment of these contaminants. The project also has innovative outreach activities involving K-12 students and their teachers.

该项目正在调查人工湿地和自然湿地在处理非点源污染方面的潜在作用，并评估这类湿地在催化除草剂和药物光解方面的重要性。该研究计划是假设驱动的，并将测试的创新想法，增加铁的湿地将促进合成有机污染物的光解产生活性氧。待研究的目标化学品包括三种除草剂和两种药物。研究结果将导致更好地了解处理有机污染物的表面湿地和利益可以累积到社会，如果人工湿地可以设计提供更好的处理这些污染物。该项目还开展了涉及K-12学生及其教师的创新外联活动。
