N3.04 Portmann 2019 ReNUWIt Annual Meeting Poster
Abstract/Contents
- Abstract
• Nonpoint source pollution such as urban stormwater is a major threat to water quality – it is difficult to identify and treat. The streambed hyporheic zone (HZ) is the “river’s liver” – it is a natural biofilter that can treat nonpoint source pollutants, such as nutrients, pathogens, heavy metals and trace organic contaminants (TOrCs).
• No established Best Management Practice (BMP) effectively utilizes the HZ. Biohydrochemical Enhancements for Streamwater Treatment (BEST) apply knowledge of pollutant attenuation in the natural HZ to small, engineered urban channels often dominated by stormwater runoff or recycled water.
• The sections of BEST engineered streambeds with biochar led to:
- Greater oxygen penetration depth in the HZ (altered redox conditions).
- Faster breakthrough of conservative tracer (Br-) in subsurface,
indicating greater HZ exchange compared to non-altered sections.
- Complete removal of Metformin in upwelling zones of the HZ.
