Sampling was conducted in duplicate at two collection points per river (before and after the community) across three seasons (dry, rainy, and transitional), resulting in 4 samples per river per season. All samples showed consistently high microbial levels exceeding international guidelines at most collection points across the three rivers. The Canchupí River exhibited the highest E. coli and total coliform counts during the dry season, with values of 1.50 × 10⁷ and 1.79 × 10⁷ CFU/100 mL, respectively. The Saguambi River showed the highest E. coli levels in the transitional season (9.42 × 10⁴ CFU/100 mL).

M. leprae was found in the Saguambi and Mindo Rivers, and H. pylori was identified in both Mindo and Canchupí Rivers.
