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

Araştırma, Aydın Regülatörünün sağ sulama ana kanalı boyunca seçilen yaklaşık 5500 ha’lık bir alanda yürütülmüştür. Bu alanda mevcut 15 yer altı ve 4 yerüstü su kaynağından Mayıs – Temmuz – Eylül aylarında olmak üzere, toplam 40 örnek alınmıştır. Bu örneklerde pH, EC, CO 2 3 - , HCO 1 3 - , NO- 2 , NO- 3 , SO 2 4 - , Cl -1 , sertlik, Na, K, Mg, Ca ve ağır metallerin (Fe, Mn, B, Zn, Cr, Co, Ni, Cd, Pb) analizleri yapılmıştır. Elde edilen veriler standartlarla karşılaştırılarak su örneklerinin kalite sınıfları ve kirlilik durumları tespit edilmiştir. Mn, B, Co, Cr, Ni, Cd, organik madde, sertlik, EC, K, Mg, Na, SAR, ESP parametrelerin sulama suyu için belirlenmiş sınır değerlerin oldukça üzerinde olduğu ortaya konulmuştur. Bu nedenle 7 nolu nokta hariç diğer su kaynaklarının sulama suyu olarak kullanılabilecek nitelikte olmadığı belirlenmiştir. Ayrıca bazı parametrelerin konsantrasyonlarının örnekleme dönemleri arasında ve noktalar arasında istatistiksel önem arz eden farklılıklar gösterdiği belirlenmiştir. Topraktan gübreler ve tarımsal ilaç kalıntıları ile yeraltı sularına karışan ağır metaller, yer altı su seviyesindeki alçalıp yükselmeler, yer üstü su kaynaklarına karışan endüstriyel ve evsel atıkların içerikleri bu değişimlerin sebebi olarak değerlendirilmiştir.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.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 ?
