Ignorance is not bliss! I have been ignorantly casting the blame of the absorbent amount of f***l coliform noted in current City of San Diego wastewater & stormwater samples as being attributed to the boom in our unhoused populations; when in fact, the bulk of the concern stems from aging infrastructure.
"Temporal trends in FIB [f***l indicator bacteria], HF183, pepper mild mottle virus (PMMoV), caffeine, sucralose, chloride, bromide, specific ultraviolet absorbance, and fluorescence index indicated that untreated wastewater flushed from the vadose zone was the main source of microbial pollution to the San Diego River, while open defecation near homeless encampments in the river margins was not a major source. We demonstrated that the combined use of caffeine/sucralose ratios and HF183 and PMMoV holds promise for identify."
In a society where false narratives are rampant, I have to hold myself accountable for not looking at the science before making ASSumptions.

Water quality benchmarks for f***l indicator bacteria (FIB) are often exceeded in many urban streams in southern California. Possible sources of elevated stream FIB concentrations within urban areas include sanitary sewer exfiltration, sanitary sewer overflows (SSOs), illegal discharges, and human o...
