Coastal Stormwater Pond Pollutants And The Potential For Development Of Antimicrobial Resistance In Vibrio And Enterococcus Bacteria, Cassandra L. Horton

Theses and Dissertations

The Southeastern coastal plain is the most rapidly urbanizing region in the United States. Associated landscape changes which increase imperviousness lead to hydrological cycle alterations, increasing runoff of nonpoint source (NPS) pollution. Urban and agricultural NPS runoff is generally discharged into stormwater ponds, which sequester chemical contaminants, nutrients, and microbes to reduce loading into coastal ecosystems. Studies of these ponds have indicated elevated levels of trace metals, antimicrobial compounds, and bacterial contamination (SCSGC 2018).

Interactions of aquatic pathogens Vibrio vulnificus and Enterococcus faecium with trace metals (arsenic, copper, zinc) and clinically relevant antimicrobials (triclosan, ciprofloxacin, oxytetracycline) commonly found in coastal …
