A significant portion of the African population relies on well and borehole water for drinking other domestic purposes. This study evaluated effectiveness four treatment methods; with 'watercare’ disinfectant, alum coagulation, Bridelia ferruginea leaf extract, filtration sedimentation quality these sources, contact times 30 minutes 1 hour. Physicochemical bacteriological analyses were conducted both samples before after treatment. The results indicated that disinfection ‘watercare’ met World Health Organization (WHO) Nigerian Standard Drinking Water Quality (NSDWQ) guidelines, except treatment, which lowered pH to an acidic level. Bacteriological assessments, using pour plate technique enumerating total bacterial count coliforms, revealed none WHO NSDWQ standards. Total counts ranged from 1.5 x 10² CFU/ml in 8.9 1.6 10³ water. identified microorganisms predominantly Gram-negative rods, including Acinetobacter baumannii, Serratia maltophilia, Myroides odoratus, Burkholderia cepacia. Gram-positive organisms included Micrococcus sp., Corynebacterium Bacillus sp. While achieved reductions coliform loads, extract had no effect. concludes are unsafe drinking, emphasizing necessity combining filtration, sedimentation, adequate
