Permits affected: NPDES NM0022292 and DP-289
- NPDES NM0022292 is the EPA permit for effluent release into the Lower Santa Fe River
- E. coli daily maximum: 410 CFU/100mL
- E. coli 30-day average: 126 CFU/100mL
- DP-289 is the NMED permit for effluent reuse and irrigation (e.g. fields)
- E. coli daily maximum: 126 CFU/100mL
- E. coli 30-day average: 63 CFU/100mL
CFU = “colony forming unit” (estimated viable bacteria cells in a sample, e.g. in 100 milliliters)
EPA E. coli Factsheet
E. coli is often used as an indicator species for other pathogens of a similar size that can be less reliable to detect. Fluctuations in the numbers are relatively normal because wastewater treatment relies on biological processes and can be impacted by factors such as storm events. However, high fluctuations can indicate the need for updated treatment systems.
