Monitoring Stormwater Basins Designed to Manage Water from Interstate Runoff in Atlanta GA
Stormwater management is a means to control water flow, treat water, and protect waterbodies. When the water is coming from roadways such as interstates, the stormwater basins ca n both control the water flow from the roadway as well as remove nutrients and other constitutes originating on the roadways. As such, the University of Georgia in cooperation with the GA Department of Transportation and American Rivers is working to install stormwater retention basins at the intersection of two major interstates in Atlanta Georgia to help control flow from the Interstate as well and remove nutrients and other constitutes. The University of Georgia Crop and Soil Sciences Department along with the UGA College of Environment and Design will conduct the monitoring of the influent and effluent of the stormwater basins while the other parties will work on the design and development of the basins themselves.
Monitoring the stormwater basins will be conducted to determine how effective the stormwater basins are at removing nutrients, other constitutes originating from vehicles, and its ability to reduce the potential overloading of the city’s combined sewer system. Stormwater originating on roadways such as the interstates has the potential of picking-up and transporting large quantities of constitutes that can pollute local waterways. These constitutes can include but are not limited to nutrients (the main pollutant to local waterbodies) and heavy metals that originate in tire rubber, oils, and other liquids from vehicles.
Monitoring of the stormwater basins will include sampling of the inlet to the basins, the effluent from the basins, and internal water samples. The sampling of the basins will begin in the summer of 2019 as background samples to better design the monitoring protocol for the basins. The sampling will also continue during the construction of the basins and thereafter in order to monitor post-construction and operating periods of the basins. The presentation proposed here, will provide data and information on the purpose of the project, how the stormwater basin is being designed, why the project is of importance to the city of Atlanta, the data collected prior to construction, during construction, and after construction. The information gathered will be helpful for the GA Department of Transportation to design other stormwater ponds in or near Interstates to help better manage stormwater and it’s constitutes. At the time of the abstract being presented, we are in the beginning stages of starting the background monitoring, but by the time of the conference we will have data from background sampling, during and after construction samples where we can present the data on the constitutes that will be of concern while managing the stormwater and protecting the downstream waterbodies.
