In this study, Ayvali surface water, Pinarbasi and Karasu spring water have been investigated according to the quality of drinking water on the basis of TSE 266 standard in months of 2014. In this regard, pH and turbidity were examinated for a period of 8 months. Nitrite, nitrat, iron, mangan, chlorine, ammonia, fluoride, lead, aluminium, copper, zinc, boron, cobalt, nickel, cadmium, chromium, mercury, barium and nitrogen were analysed in December 2014. Bacteriological analyses, such as fecal coliform, Escherichia coli and total coliform were examinated by membrane filtration method. All samples were carried out determination of permanganate by titrimetric method. According to the obtained results, the turbidity values of samples collected from all three sources were under 2 NTU and the color parameters of the limit values were below the standard. As a result of the analyses of the samples from all three sources it have been seen that the amounts of metal ions were monitored below the standart. Total hardness (calcium + magnesium) amount was within the limit values of the water source, although it was understood that the water enters into medium hardness in French hardness class. In terms of bacteriological analyses free chlorine in water samples at a level of 0.5 ppm, the source did not contain coliform bacteria. According to these data, physical, chemical and bacteriological characteristics of drinking water were understood it was suitable for World Health Organization drinking water standarts (WHO) and TS-266 standards in terms of quality parameters compared to water which was agreeabled to human consumption.
