Nature as Wetland's Purifier

Can biological systems be used to enhance water quality to supplement traditional wastewater treatment plants in cities?

Wetlands have long been recognized for their ability to effectively reduce unwanted nutrients and chemical compounds to improve water quality. In the last several decades there has been a push from municipalities to build and use wetlands as an extension of water treatment plants. Despite these benefits for water quality, constructed wetlands are also emitters of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. In collaboration with colleagues at Arizona State University, we quantified these greenhouse gases from an arid urban constructed wetland in West Phoenix called Tres Rios. We collected and quantified gas emissions for over two years and are currently working on publishing our results.
