Physicochemical and Bacteriological Analysis of Well Water in Kaduna Metropolis, Kaduna State

摘要

The study was carried out to determine the physicochemical and bacteriological quality of well water from Kaduna metropolis. The physiochemical quality of the water was analyzed using FAO (1997) method and the result obtained showed that the water sample was acidic, some neutral but they all fell within the range as recommended by WHO, and NAFDAC, the water sample fell within the recommended range for Nitrite, turbidity, conductivity and chloride. The bacteriological quality of the water was also determined by most probable number technique, the total coliform count and the differential E. coli count in which several tubes with diluted buffered solution to dilute the water sample and then incubated for 24 hrs, this is called the presumptive test while for the confirmation test, positive tubes from the presumptive test were inoculated into separate growth medium for total coliform and E. coli and then incubated. The results obtained showed that total coliforms were observed ranging from 11.0 to 63.0 cfu/ml with Sabon Tasha (TS) having the highest counts and Nasarawa (NS) with the least counts, while only two sites—Sabon Tasha (ST) and Kakuri (KK)—were recorded to have feacal contaminations. E. coli was identified suggesting that the water samples from the two were having recent feacal contamination.
