MICROBIOLOGICAL QUALITY OF WELL WATER IN YELWA KAGADAMA AREA OF BAUCHI METROPOLIS
Abstract
ABSTRACT
This study assessed the microbiological quality of seven well water samples collected from various locations in Kagadam area of Bauchi State, focusing on total coliform and Escherichia coli contamination. The membrane filter technique was used and the results from indicated total coliform counts ranging from 40 CFU/100 ml (Kasuwan Mata) to 213 CFU/100 ml (Isah Location), all exceeding the World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ) guidelines, which require zero coliforms per 100 ml. Samples S1, S2, and S7 recorded especially high contamination, suggesting significant faecal pollution and poor sanitation. E. coli was present in all samples, with counts ranging from 2 to 51 CFU/100 ml also far exceeding recommended safe limits. The highest E. coli load was observed in Angwan Sodom (S2), indicating fresh faecal contamination. The presence of E. coli highlights potential risks of gastrointestinal infections and other waterborne diseases. The results confirm that untreated well water in the study area poses serious public health risks, calling for urgent water treatment interventions and improved sanitary practices to safeguard community health.
