Abstract: Wastewater of the discharge channel was also used for irrigation of the agricultural area near the channel during the spring period. Chemical composition of the irrigation water is very important because the source of irrigation is untreated wastewater. The concentrations of 8 heavy metal elements in three sampling points, between Konya municipality and Tuz Lake, on the Konya main discharge channel were investigated for 6 months period that results displayed significant enrichments in Zn, Cu, Mn, Cr, Ni, Pb, Co and Cd. The major factors determining the quality of irrigation water are its salt content (salinity); its salt composition (sodality); its sediment load; and type and amount of toxic constituents. The aim of the study was to undertake the quality parameters of main drainage channels, including sewage effluent and their effects on soil contamination for Konya province of Turkey. For this purpose, water samples were taken from irrigation areas and analysed for determining the level of contaminants. According to the results, crop patterns might be affected from poor quality irrigation water. Zn, Cu, Mn, Cr, Ni, Pb, Co and Cd are 0.582, 0.035, 0.086, 0.042, 0.026, 0.027, 0.019 and 0.013 mg/L respectively.
