    In this study, the quality of irrigation water was determined in Aksaray region which is one of the most important agricultural lands of Turkey, the facts causing pollution were specified and the precautions that should be taken were discussed. Within the scope of this study, 38 samples were taken from the water of 24 wells, 4 dams, 9 ponds and 1 source water. In order to use the data more effectively, irrigation water quality index map of Aksaray region including the results of the samples (EC, SAR, B, Cl-, NO3-, HCO3- and pH) was prepared by using Geographic Information System (GIS). According to irrigation water quality index map, all surface water sources were found to be suitable for irrigation with high and medium irrigation water quality index. EC, SAR, Cl, HCO3 values were found as high in Acipinar well and Aratol well regions whereas EC and Cl values were high in Taspinar well region. It was determined that underground water sources have low irrigation water quality index value along in the range of Taspinar region and Tuz Lake whereas they have generally medium irrigation water quality index value. The soil being heavy-texture and salty structure in the region and the level of ground water being high were caused by lack of adequate drainage system. For this reason, good and adequate drainage system should be configured in order to provide no increase in salt accumulation in the soil, to get an opportunity for more appropriate land use and to increase the yield per unit area.

    A research for water pollution of melendiz stream in terms of sustainability of ecological balance
    (North Univ Baia Mare, 2011) Karadavut, İbrahim Samet; Saydam, Ahmet Cemal; Kalıpçı, Erkan; Karadavut, Sedat; Özdemir, Celalettin
    In order to provide the continuity of ecological balance, the presence of water as well as its quality is of capital importance. In this study; a research was carried out about the water pollution in Melendiz stream which feeds the Mamasun dam and meets the drinking and usage water need of Aksaray Plain and its environment. The samples were taken from totally 14 stations between 2006 and 2009 (February, June, September, December) throughout the whole study. These samples were analyzed in terms of 22 parameters, its water quality was determined by evaluating according to "Continental Water Sources Quality Classification Criterions" (Republic of Turkey Ministry of Environment and Forest / Regulation for Water Pollution Control) and thus the factors that cause pollution in Melendiz stream were determined. Moreover, the seasonal variations in quality criterions of Melendiz stream were determined and the precautions necessary to minimize the pollution were discussed. As a result of the research; the effects of domestic wastewater, thermal spring wastewater and wastewater of touristic plants as point pollution sources and agricultural drainage water as a common source were determined. In point sources, organic substances and nitrite were determined whereas, nitrate pollution related with excess fertilizer usage was determined in common sources. The concentrations of these parameters increased especially in dry spells and caused a certain decrease in water quality. According to continental water quality classification criterions, the surface water had IIIrd and IVth class water property in terms of especially nitrate, nitrite and total nitrogen and IInd class water property in terms of other parameters. When the analysis results of samples taken between 2006 and 2009 were compared, it was determined that the amount of pollution increased in time. It was also observed that the surface water of Melendiz stream was exposed to pollution by point and common sources and the quality of water decreased gradually.
