Abstract
Bromide and iodide are naturally occurring trace elements most often found in the ocean and seawater. While disinfectants are vital to getting healthy, sustainable water, they also introduce harmful Distribution By- Products (DBPs). These disinfectants react with the Bromide and Iodide creating DBPs. These DBPs can be carcinogenic and cause some reproductive issues. Furthermore, the amount of harmful brominated and iodinated DBPs in the water correlates with the amount of Bromide and Iodide pre-existing in the water. In this research, Bromide and Iodide levels were measured in river water. We predict that the area below the fall line of South Carolina will have using an IC system. The IC system measures the concentrations of the anions by absorbing the ions. This method measures the concentrations of the anions by absorbing the ions, which allowed us to find the concentration of bromide and iodide in parts per billion (PPB). Overall, data suggests support for our hypothesis that the area below the fall line would have greater concentrations of Bromide than the area above the fall line. However, Iodide was not detected in large concentrations as Bromide was. We also noticed that the water samples that had rainfall had lower concentrations of Bromide than we expected. These results are important to the overall research because they show that below the fall line more DBPs exist. People who live below the fall line may have a higher chance of consuming disinfected drinking water containing DPBs.
