Progress 01/22/15 to 09/30/17
Outputs Target Audience:During this reporting period, the PI and graduate research assistant sought to improve the knowledge of pollutant removal capabilities of bioretention basins and wetlands through the dissemination of critical information to students, student groups, non-profit organizations, local and state government, and tree advisory boards. Changes/Problems:As mentioned in the 2016 report, we decided to focus our attention on urban wetlands as a BMP. This was done in consultation with MTAC and Metro Stormwater. As a result, data has been collected at the Tennessee State University wetland. What opportunities for training and professional development has the project provided?This project has provided training and professional development to one graduate student. This has resulted in three accepted abstract submission and three presenations. How have the results been disseminated to communities of interest?The results have been disseminated via conference presentations and publications. What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts What was accomplished under these goals?
Lands which are seasonally wet over a period are referred to as wetlands, and they are a vital ecosystem because of the ecosystem services they provide. At a watershed scale level, wetlands improve water quality. Anthropogenic activities associated with urbanization significantly influence wetlands mainly through altering the dynamics of nutrients and pollutants. Nashville Tennessee is rapidly becoming urban. According to the U.S. Census Bureau, Nashville has an annual population growth of 1.8% in the last five years (2010-2015). Wetland monitoring programs can assist us in reflecting the impacts of urbanization and land use on waterbodies. Research related to wetland efficiency can assist in determining how well these wetlands remove pollutants in the Nashville urban areasThis research is carried out on the TSU research wetland located at the greenhouse facility and the Ed Temple Blvd and Walter Davis Blvd bridges. A specific objective is to estimate loads and removal rates of nutrients and heavy metals. This study evaluates the physicochemical parameters of water quality parameter in the wetland. Spatio-temporal variations are observed all through the study period (FEB 2016 - JAN 2017). Using many statistical methods and data reduction techniques like factor analysis and PCA, we analyzed correlations amongst different variables and used our findings as a premise to identify possible pollution sources. Results have shown a (32%, 25%, 8% and 3%) removal efficiency for (S, Na, Ca and P) respectively. There were traces of Al, Pb, Cu, and Ni in minute concentrations within our samples with no significant impacts. Significant variations in concentrations of DO, specific conductivity and salinity have been observed for the current data we possess. Specifically, we have: 1. Collected random (Sarkar&Upadhyay,2013) grab samples via a long-handled plastic dipper according to the Department of Environmental Protection. We have collected from several points to get a better representation of the population (Weiss et al., 2002). 2. Collected random (inlet/outlet) composite samples twice a month from February 2016 through December 2016 (Scholes et al., 1998). 3. Placed a field monitoring multi-parameter sonde at inlet and outlet. Water quality parameters such as conductivity, pH, DO, temperature, and turbidity are measured in situ and recorded daily. 4. Collected time-weighted discrete storm samples during one single storm event. 5. Analyzed water samples for (NO3-N)and (NH3-N) using a DR 3900 benchtop VIS spectrophotometer. 6. Analyzed correlations amongst different variables and use our findings as a premise to identify possible pollution sources. Results have shown a (32%, 25%, 8% and 3%) removal efficiency for (S, Na, Ca and P) respectively.
