Heavy Metal Concentration in Water and Sediment of Winton Lake, Ohio

Adam P. Mather, Ralph C. Layland, and Jeffery M. Hollifield

To ensure that the environment is not negatively impacted by pollution, it is crucial to determine the heavy metal concentration in a watershed. High levels of heavy metals can be hazardous, making it crucial to ensure that these concentrations are within limits set by the Environmental Protection Agency (EPA). This study focuses on establishing the heavy metal concentration (including cadmium, chromium, lead, etc.) in water and sediment from various locations around Winton Lake, Ohio. Ten samples of both water and sediment were collected, and heavy metals were extracted from the sediment using EPA Method 3050B. Water samples were preserved with nitric acid and stored in a refrigerator. Graphite furnace atomic absorption spectroscopy (Perkin-Elmer Aanlyst900T) was used to analyze the samples, and a calibration curve was created to determine the concentrations of metals at each site. The results were then compared to the EPA's established guidelines.
