This investigative research was carried out with the purpose of determining the source of contaminants present in the surface waters flowing through the Wright State University woods. Five sample sites going from upstream to downstream namely; Inflow to Nutter Center Pond (INNCP), Nutter Center Pond (NCP), Outfall 21 (OTF 21), Burley, and Outfall 15 (OTF 15), were sampled over a time period spanning from June 2020 to January 2021. Samples collected were analyzed for Escherichia coli (E. coli) using 3M™ Petrifilm™ E. coli/Coliform Count (EC) plates, select anions (Phosphate PO43-, Nitrate NO3-, Sulfate SO42-, Fluoride F- and Chloride Cl-) using a Dionex ICS-1600 Ion Chromatograph (IC) system. General water quality parameters were measured using a YSI Professional Plus Electrochemical Water Quality Probe. All selected anions except nitrate and phosphate were found at all sample sites along with E. coli in varying concentrations. The data indicates that the INNCP is the source of contamination to the NCP and that there are other sources of contamination to the sites downstream from the NCP from within the woods. |
