Analysis of legionella and Some Chemicals in Water Samples in Mardin Province

Abstract

In this study microbiological and chemical analyzes were carried out on water and swab samples taken from two water wells, a water tank and taps of buildings belonging to a public institution in Mardin Province. In these specimens the presence of Legionella and its serogroups as well as the parameters such as chlorine, nitrate, nitrite concentration, pH level and electrical conductivity were analyzed. While Legionella growth was not observed in 25 water samples, L. pneumophila serogroup 1 was detected in 4 of 25 swab culture samples taken from the same places. The pH values of water samples ranged from 7.53 to 8.02 the lowest pH value was observed in well no 1 as 7.53 while the highest was observed in well no 2 as 8.02. The lowest electrical conductivity value was measured at well 2 as 376.44 mu S cm(-1) and the highest was measured as 446.57 mu S/cm from well 1. As a result of the analyzes made in our research nitrite was not detected in any of the water samples. Whilst the nitrate amount was found to be the lowest with 4.30 ppm in the well, the highest with 10.85 ppm in the well 2. The chlorine values in the well 1 and 2 from which water samples were taken and the main tank were measured as 2.21, 2.05 and 2.43 ppm respectively. These values were found to be in the range of 1.68-1.73 ppm in the samples taken from the building taps.
