Abstract/Contents

Abstract: • Untreated urban stormwater runoff conveys nutrients, pathogens, sediment, heavy metals and trace organic contaminants (TOrCs) to waterways, contributing to water quality impairment.
• Biohydrochemical Enhancements for Streamwater Treatment (BEST) modules apply knowledge of pollutant attenuation in the natural hyporheic zone (HZ) to engineered urban drainage channels often dominated by stormwater runoff.
• Previous work at the Mines Park testbed shows that BEST increases HZ exchange and contaminant biodegradation rates.
• Theoretical calculations indicate that BEST amended with geomedia may be a promising option for heavy metals retention. Laboratory testing has confirmed that several amendments hold potential for heavy metals retention:
- Manganese oxide-coated sand (MOCS)
- Biochar
- Iron aggregate
- Mulch
- Zeolite
