Florida as a laboratory for global urbanization, sea level rise, and future health risks of drinking water sources.
Goals and Objectives
Sea-level rise (SLR) resulting from climate change is expected to increase saltwater intrusion and subsequent contamination of fresh groundwater. In the past the major concern with this contamination was chloride (Cl–) and sodium ions, which are the major constituents of saltwater and cause unpalatable taste. An overlooked process during saltwater intrusion is the co-transport of bromide ion (Br–) with Cl–. Although Br– is present in saltwater at much lower concentrations than Cl–, Br– can form toxic disinfection byproducts (DBPs) during water treatment whereas Cl– and total dissolved solids (TDS) are predominantly an aesthetic concern. Accordingly, the objective of this research is to quantify the impact of SLR on the potential to alter groundwater chemistry and increase the formation of brominated DBPs during water treatment. The research project is underway by pursuing four specific aims: 1. Model saltwater intrusion in a coastal aquifer for one hydrogeologic region in Florida under different projections of SLR; 2. Quantify the variability in the ratio of bromide-to-chloride (Br–/Cl–) in a coastal aquifer in Florida under different spatial and temporal scales; 3. Model the formation of bromine-containing DBPs formed during drinking water treatment for varying degrees of saltwater intrusion; 4. Develop an applied science adaptation framework by identifying current coastal drinking water supply management practices and policies, the changes needed based on the new information about DBPs, and the barriers and opportunities for adaptation.
