Physical, chemical, and bacteriological properties of municipally supplied water and well water in selected towns and the city centre (Niğde, population 76,000) of the province of Niğde, located in central Anatolia, in Turkey, were investigated in this study. A composition of 70 samples were collected, 31 from Niğde city centre; 17 from Bor; 8 from Ulukişla; 6 from Altunhisar; 6 from Ciftlik and 2 from Camardi. Analyses showed that all the samples collected were found to have been chemically safe to consume for domestic purposes. Twenty-three water samples were found potentially unsafe because of the existence of coliform bacteria in them, which was probably caused by the inexistence of sufficient chlorination. Physical tests indicated that 11 water samples were found to have deposit; therefore, the use of such water causes risks where human health is a concern, based upon Turkish national standards (TSE, 1984).
