Abstract
  • With a growing demand for renewable sources of freshwater around the world, stormwater offers a potential solution. However, various pollutants can be present within stormwater, such as antibiotic-resistant bacteria, that present a danger to human health if stormwater is used for agricultural purposes. Biochar has the capability to remove bacteria from stormwater, but how well it retains these bacteria has not yet been well studied. In this experiment, three columns were exposed to synthetic stormwater collected from the OSU-Benton County Green Stormwater Infrastructure Research Facility (OGSIR) and inoculated with an ampicillin-resistant and susceptible strain of Escherichia coli. When the concentration of E. coli entering the columns was the same as the concentration in the effluent, autoclaved stormwater from the OGSIR facility was run through the column and the effluent concentrations were determined. No difference was found in release levels between susceptible E. coli and ampicillin-resistant E. coli. No difference was found in release between the soil and mixed columns either, though the biochar column took a longer time to release E. coli.
