Abstract: Background and Objective: There is need for alternate quick-search of pathogens’ distribution in community water sources, instead of the cumbersome “Escherichia coli ” detection. Parasites were evaluated as veritable indicators of faecal Enterococcus contamination of surface waters, using Adada River in Nigeria as case-study. Materials and Methods: Seventeen parasites of human biotic origin (in dry season) and 13 (in the rainy season) isolated from the river (at specific geographical coordinates) were analyzed for their quality and quantity (using Stoll’s Counting Technique) and connected (using Pearson’s correlation analysis) with the distribution of the river’s isolated Enterococcus sp. The parasites consist of: Taenia sp., E. coli, E. histolytica, B. coli, cercaria/miracidia, S. mansoni, S. haematobium, A. lumbricoides, Giardia sp., hookworm, T. trichiura, S. stercoralis, I. butschlii, C. mesnili, E. nana, B. hominis and H. diminuta, while the 13 consist of: Taenia sp., E. coli, E. histolytica, B. coli, S. mansoni, A. lumbricoides, Giardia sp., hookworm, T. trichiura, S. stercoralis, I. butschlii, C. mesnili and E. vermicularis. Result: Biological indices from the analysis, revealed very strongly significant correlation relationship of Enterococcus sp. with the presence of Taenia sp. and cercaria/miracidia, in the dry season and C. mesnili in the rainy season. Conclusion: From the evaluation, potential index analysis indicated that Taenia sp., cercaria/miracidia and C. mesnili could serve as markers for the faecal bacteria indicator and possible index for future monitoring of the potability of this surface water. The methodology is straight forward, cost effective, less cumbersome than other currently existing approaches.
