Determination of pollution level of some ground and underground water sources in Aydın region

The research were carried out in approximately 5500 ha area chosen a long the right irrigation main canal of Aydın Regulator totally 40 samples were taken from 15 under ground water and 4 ground water sources in taking place in the area in May ? July ? Semptember. pH, EC, carbonate, bicarbonate, nitrit, nitrate, sulphate, chlorine, water hardness, Na, K, Mg, Ca, and heavy metal (Fe, Mn, B, Zn, Cr, Co, Ni, Cd, Pb) content analyses were performed. Quality classes and pollution condition of water samples were determined by comparing with standarts and the results obtained from the analyses. The results showed that parameters of Mn, B, Co, Cr, Ni, Cd, organic matter, EC, K, Mg, Na, SAR, ESP, water hardness were quite higher than the limits determined for irrigation water. Therefore, these water sources were not classifed as irrigation water having good qualities. In addition concentration of rowe parameters were found statistically significal some sampling terms and points. Fertilizers and pesticides coming from agricultural areas, heavy metals, changes in level of aunder ground water, industrial and urban wastes were reparded as the possible reasons these changes.
