| Abstract: | The aim of the study was to examine microbiological risk of public water system of Tefenni (Burdur) region, which is located
in southwest of Turkey. The important pollutants of the study area are cattle breeding, use of animal manure for agricultural
activities and unsanitary water supply system and water tank. The microbiological condition was assessed using total coliform
bacteria in water samples, which was collected from springs, wells and water supply system of Tefenni county and villages
during the period January 2009 and December 2009. Microbiological analyses indicate that failure rate (positive samples) was
43% for sampling period. There was greater consistency among failures of total coliform indicator standards during spring
and winter than during autumn and summer. This observation was explained partially by a significant positive correlation with
the rainfall amount (r
Pearson = 0.70, P = 0.01). In addition, the microbiological risk assessment was made using modified sanitary inspection forms and prepared
final score map. Compared with final score and microbial pollutant maps of the study area, it has been shown that water resources
having high risk score were directly proportional with pollutants related to land use. |
