Experimental Flood to Study Nitrogen Fluxes and Transformations

Storm water retention basins are a ubiquitous feature in Phoenix’s residential and commercial areas. They concentrate water, nutrients, and pollutants from storm water runoff. While these basins can be important sites for improving storm water quality and recharging groundwater, they may also be sources of greenhouse gases.

In this video, CAP LTER graduate student Libby Larson experimentally floods a storm water retention basin at a north Phoenix elementary school in order to better understand how nitrogen behaves in this system.
