Abstract :
Background and aim. The Nyong is one of the main sources of drinking water supply in Cameroon. The protection of its integrity is very important. A prospective study was conducted from January to March 2012. The objective was to assess the physicochemical quality of the Nyong waters. Materials and Methods. Physicochemical parameters (colour, temperature, suspended solids, pH, electrical conductivity, dissolved oxygen, nitrates and orthophosphates) were measured according to the usual techniques. Results. Three physicochemical parameters (electrical conductivity, oxygen and nitrate concentrations) were in compliance with water quality standards, two were non-compliant (colour and orthophosphate concentration) and three varied in space and time (temperature, pH, concentration of suspended solids). Conclusion. The Nyong water is not recommended for drinking water purposes. However, it was found to be generally of good quality for bathing (class A) and for the production of water for human consumption (class A1). Moreover, an association could be established between the physicochemical of this water and complaints of itching expressed by some residents.
