Thesis Abstract

Water is one of the indispensable resources for the continued existence of all living things including man. The provision of an adequate supply of safe drinking water was one of the eight components of primary health care identified by the International Conference on Primary Health care in 1978. This study investigated the bacteriological quality of sachet-packed water in Imo State, Nigeria. A total of five sachet water collected around Imo State University premises where examined for registration number, manufacturing date, expiry date and net volume (cl).

Physiochemical analysis carried out showed that these sachet waters where in accordance with the World Health Organization (WHO) Standard. The sachet waters cultured on bacteriological media showed the presence of coliform bacteria and other pathogenic bacteria. The bacteria isolate form the water samples are; Salmonella species, Coliform species, Escherichia coli, and Enterobacter species.

Results showed that 100% of the packaged water samples examined were either untreated or produced under unhygienic conditions. High aerobic colony counts in the order of 106 were recorded from all of the samples examined. The findings show that 90% of packed pure water sold in the country are not fit for human consumption and are hazardous to health. This calls for urgent attention by regulatory bodies and law enforcement agencies in the country.
