Chlorine demand and parameters determining chlorine consumption in traditional shallow well water of Agboville (Côte d’Ivoire)

Résumé

The consumption of traditional shallow well water by low-income populations in Agboville’s city could expose these people to health risks. The aim of this work is to assess chlorine demand and physicochemical parameters determining chlorine consumption of these waters.  Methods described by French Standards Association were used to determine chemical parameters and carry out chlorination test. Chlorine demand values range from 6 to 72 mg.L^-1. High chlorine demands are observed in wells with strong ammonium, organic matter, and turbidity and conductivity values. A relationship exists between chlorine demand and the above parameters.
