Contaminant Removal by Edge-of-Field Wetlands
Water Quality and Ecology Research
2009 Annual Report
1a.Objectives (from AD-416)
Vegetated edge-of-field flow in floodplain ecosystems can reduce runoff related contaminants. This project seeks to better understand and measure the efficiency of contaminant removal by constructed wetlands, vegetated ditches, and other low-cost management practices needed to improve water quality. These biologically-focused experiments will also further define ecosystem impairment from agriculture and measure the positive effects of potential best management practices.
1b.Approach (from AD-416)
Investigators will cooperate on edge-of-field studies in semi-aquatic and aquatic drainage systems to facilitate ARS efforts in improving the quality of runoff water from agriculture. In an effort to better manage water by edge-of-field practices, specific studies will measure standard WQ parameters and state-of-the-art invertebrate toxicity in controlled experiments for current use insecticides and agriculturally-applied nutrients.
This is a newly-established agreement and research is just being established. No progress to report.
