An assessment of the health and social economc implications of satchet water in Ibadan, Nigeria: A public health challenge

Abstract

The inadequacy of pipe borne water in Ibadan Metropolis is almost endemic. This inadequacy is both in quantity and quality of the public water supply. As an alternative to the water supply, small scale industrial concerns came up with ‘PURE WATER’: 0.5Litre water in nylon sachets, which are electrically heated, sealed at both ends and widely patronized by both low and middle class Nigerians. The objective of the study was to find out the quality of such pure water. Stratified, simple random sampling procedures were used to select 78 samples from 20
brands of sachet water from important hawkers/vendors. The samples were subjected to physical, chemical and bacteriological analysis. For chemical analysis, Hanna’s 100 spectrophotometer plus chemical reagents were used. The water samples were assessed for
coliform and other intestinal bacteria using MKC cowkery broth (MM) and Brilliant Green Bile Broth (BGBB). Multiple tube method was employed. The result showed that the physical parameters were within W.H.O limits for drinking water quality guidelines except for pH which
ranged from 6.6 - 9.7. Some chemical parameters were also within the W.H.O guideline values. However; aluminum which concentration ranged from 0.00 — 0.34 mg/l, fluoride concentration ranged from 0.01 — 1.87 mg/I and cyanide concentration ranged from 0.000 —0175 were not. Bacteriological analysis, showed that five (5) or 6.4% of the samples tested fielded bacterial growth. Bacteria produced included: Klebsiella sp., Streptococcus faecalis and Pseudomonas aeruginosa. The enforcement of the regulation guiding water quality before the National Agency for Food and Drug Administration Control (NAFDAC) to comply with the drinking water qualities guideline values as recommended by W.H.O, becomes urgent.
