Correlation coefficients of the fecal indicator raw wastewater concentration (Log10GC/L), fecal indicator flow normalized wastewater concentration (Log10GC/Day), and flow rate (L/Day) with the estimated population served across each study site.
Fecal indicator correlations include analysis results of PMMoV, crAssphage, and F+ Coliphage.
