ABSTRACT:
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.
