A recent investigation into the quality of sachet water in Senegal has brought to light alarming levels of contamination, signaling a significant public health concern. From August to September 2018, a dedicated team of four researchers from the prestigious Cheikh-Anta-Diop University in Dakar undertook a comprehensive study. They meticulously collected 60 samples of sachet water from five of Dakar’s largest and most frequented markets: Tilène, Thiaroye, Colobane, Grand-Yoff, and Soumbédioune.

Sachet water, typically sold in small plastic pouches ranging from 300 ml to 500 ml, is an exceptionally popular and affordable source of drinking water for many Senegalese residents. The collected samples represented 15 different brands widely available across the capital.

The results of the analysis were stark. Two critical tests, specifically designed to identify the presence of microorganisms such as molds and various types of bacteria—including those originating from the environment or indicative of intestinal presence—revealed contamination levels far exceeding the established standards set by the World Health Organization (WHO).

A substantial 83 percent of the water sachets examined were found to be tainted with bacteriological germs. Even more concerning, 15 percent of the samples showed the presence of coliforms, a strong indicator of potential contamination by fecal matter. These figures point to a severe shortfall in hygiene standards throughout the production chain.

The university study unequivocally attributes these findings to «defective hygiene in the transformation process» of the water. Researchers underscored the existence of «a sanitary risk» for «the population of Dakar who consume these waters». They stressed the imperative to «prevent consumers» from potential harm and to enhance «control over the sale of packaged sachet water» to ensure public safety.

In a related enforcement effort, Senegalese police forces acted decisively last May, successfully dismantling 12 clandestine production facilities for sachet water located on the periphery of Dakar. This operation highlights ongoing governmental attempts to curb unregulated and potentially hazardous water packaging operations in the region.
