Linear regression coefficients β₁, β₂ and β₃ of the hydrologic driven model B_i=β₀+β₁rain₁_i+β₂rain₂_i+β₃d_i+ε_i (Eq. 1) obtained for E. coli and Enterococcus, where the coefficients represent fecal indicator bacteria (FIB) most probable number (MPN) per 100 ml per cm (β₁, β₂) or km (β₃). The 90% confidence intervals are listed in parentheses under each regression coefficient.

	E. coli	Enterococcus
R²	0.61 (F=134.20, p<0.00001)	0.04 (F=3.85, p=0.02)
β₁	48.4 (44.40 to 52.40)	112.6 (36.10 to 189.20)
β₂	6.5 (1.80 to 11.30)	−33.3 (−124.30 to 58.0)
β₃	−0.62 (−1.15 to −0.08)	−0.11 (−11.20 to 10.97)
