In order to contribute modestly to the assessment of lead content in the effluent of the WWTP in the scope of Sebkha gardener, the samples were taken at the WWTP between October and December 2011. In addition to studying the evolution of lead, electrical conductivity, chlorides, sodium and chemical oxygen demand were studied with the statistical analysis methods were applied to the results obtained. The results show that lead levels recorded at the effluent of the WWTP ranging from 104.5 µg/L and 176.5 µg/L. The statistical analysis of results shows that lead is strong and positive correlation with electrical conductivity, chloride and sodium and positively moderately correlated and significant with the Chemical Oxygen Demand.
