Low impact developments are one of the main tools to improve stormwater quality. Stormwater control measures (SCMs) have been developed to help address the growing urban stormwater problem. Stormwater basins such as detention and retention basins are used to address these concerns. These basins commonly include some soil-based media to promote water filtration and storage. Furthermore, they improve water quality through sedimentation, filtration, and biological transformation. The nitrogen cycling genes in the soil of the basins and the changes through the season is an essential factor affecting the efficiency of the basin in removing the nutrients, which is our main focus in this study. In this study, we study one detention basin on the Edwards Aquifer's recharge zone, the primary water source for San Antonio. We studied the nitrogen cycle in the basin based on the nitrogen species concertation in the stormwater samples and comparing them to the genes responsible for nitrogen cycling in soil samples.
