Sediment Influence On Escherichia Coli Variability In The Rio Grande During The Dry Season In The South Valley, Albuquerque, New Mexico, Kate Wilkins

Water Resources Professional Project Reports

With Escherichia coli (E. coli) being a widely used indicator of pathogen contamination, concentrations need to be fully understood to create effective best management practices for water quality managers. While management and impairment standards are focused on concentrations in the water column, there is research showing that E. coli attaches to sediment in the river and acts as a reservoir for E. coli. The Middle Rio Grande in the South Valley, New Mexico is classified as an impaired reach because it exceeds the E. coli water quality standard. Exceedances are commonly seen during the wet season in high flows, but …
