Silivri-Çatalca-Büyükçekmece bölgesinde içme ve kullanma sularının bakteriyolojik yönden değerlendirilmesi

Abstract

60 has been thought that pollution of spring was as sociated with the leachte and utilization of mannure, while the pollution of water distribution system was associated to the lack of infrastructure, and the negatif pressure in the water tubes, 63.4% of the samples from Büyükçekmece, 60,4% of samples from Çatalca and 56% of samples from Silivri were not clean. The pollution increases with the density of population and the increase in anautorized connstruction zone. The samples taken in summer and in autumn were significantly more dirty than those taken in winter and in spring. This has been related to the increased population of the region and the increase in water consumption in summer. In addition, the infrastructure was also insuficient. There was no difference in samples from wells within months. Conversly, the samples from springs and from water distribution systems were differents. It was concluded that the ground water level was deeper and it was not affected from the pollution and raining on the ground. Results from this study indicate that the water transport in rural areas is inadequate and unhealty; there is a danger of epidemy and it must take precautions. The urgent precautions are to awake and educate the people, to learn to chlorinate. Moreover, it is thought that to apply legal channels, to save the zone around the wells and springs would decrease the pollution. Furthermore, the pollution factors may be removed and hygienic infrastructure may be constructed,59 SUMMARY In this study, it has been ivestigated experimentally the microbiological pollution of water resources and distribution systems in the rural area which includes Büyükçekmece, Silivri and Çatalca in Istanbul. In each region, the samples of water resources (i.e; springs and wells) and of water distribution system have been analyzed bacteriologically. The research was done on total 1326 samples, which were 256 of well, 537 of spring and 533 of water distribution system. E.coli was selected as microbiological indicator and the amount of this indicator was determined with the fermentation tube method concentration of E.coli of the samples was considered to indcate the microbiological pollution of waters. The experiments were done according to the standart procedure. The results have been evaluated statistically and following conclusions and comments have been given; 78% of samples of well water, 60% of samples of spring and 50% of samples of water distribution system were found bacteriologically dirty. The high pollution of well water was related to the caisson type wells, abscence of prevention zone around the well, closeness of wells with septic tank and carelessness to the hygienic laws (i.e; to utilize bailer or pot).
