PHYSIO-CHEMICAL AND MICROBIAL ANALYSIS OF SACHET WATER IN OYE AND IKOLE LOCAL GOVERNMENT AREA OF EKITI STATE.

 ABSTRACT

In the bid to ensure adequate water supply, packaged water has been introduced to provide safe and affordable drinking water. In spite of the varying levels of contamination, sachet water is still well accepted. This study therefore employed both quantitative and qualitative research designs to draw out survey and semi - structured interview responses. The study shows the perception of respondents based on the various sachet water brands, consumption pattern, sachet water safety, price, patronage and, attitudes towards the cross - checking of labeling requirements and respondents' perceived quality of sachet water.

The samples were analyzed physico-chemically and bacteriologically. Eight brands labeled A - H were collected from sachet water vendors (4 samples per area) and were analyzed using standard methods and procedures. Results obtained were compared with WHO standards for drinking water. The Physical examinations of the samples showed they were colourless, tasteless with no offensive odour. The pH values were within the stated WHO standards (6.50 - 8.50). Bacteriological analysis showed that sample D from Ikole (18.00 ± 0.58) MPN/100ml showed positive coliform count and therefore unfit for consumption since they could also contain other microorganisms concerned in gastro-intestinal water borne diseases. The aerobic mesophilic count for sample D from Ikole (2.1 x 102) exceeded the WHO (1.0x102) standard. This might be as a result of improper handling, location of water source close to dumping site, purification procedures, and unhygienic handling after production. All other chemical parameters were within the WHO values. This study advocates proper water treatment by water manufacturers and strict monitoring by the regulatory agency.
