Microbiological screening of pure water sold in Kano Metropolis.

Abstract

Microbiological examination for coliform using membrane filtration technique was carried out on twenty different brands or “pure water” samples collected from different areas within Kano metropolis. Six (30%) of the brands showed coliform count of less than one count/100 ml. These were graded as excellent. Eight (40%) of the brands have a coliform count ranging between 1 and 3 per ml and were graded as satisfactory. Similarly, six (30%) of the samples showed coliform count ranging from 4 – 6/100ml and were graded as intermediate in accordance with the recommended standard of WHO (1970) and EC (1980). It is recommended, therefore, that NAFDAC in Kano State
should expedite action towards enforcing the laws for good quality assurance in this industry.
