The objectives of this study were to determine some Physical and chemical properties of wastewater in N’Djamena city in Chad and to evaluate
their impact on the environment. The Chemical parameters including dis-solved oxygen and turbidity, Pb, As, Cd, Ni, and Cr. This study also
aims to identify the health risks resulting from increasing concentrations (of these minerals). Samples were collected from four different
sites and analyzed according to standard methods. The results showed that the values of most parameters are beyond the World Health Organization
recommended for wastewater discharge. Intensive investigations were recommended to cover the analysis of some chemical properties such as:
SO4-2, NO2-, Cl- and microbiological parameters, for better assessment the degree of pollution.
