Research of drinking water quality, especially in a large settlement like Tbilisi (the largest center of population in Georgia) by using modern methods and equipment is the actual task of research of water resources ecological conditions. This work presents the data from research of drinking water quality parameters, the main five physical-chemical parameters – specific electrical conductivity, total dissolved solids, salinity, pH and water temperature, in different districts of Tbilisi city and its suburbs. In the course of a year we received data for the controlled points of Tbilisi city vary as follows: pH in the range of 6.75–7.51; total dissolved solids – from 115 up to 185 mg/L; specific electrical conductivity from 231 up to 369 μS/cm; salinity from 0.12 up to 0.18 ppt. The physical-chemical parameters of water quality for Tbilisi city suburb, in the course of a year vary as follows: pH in the range of 6.7–7.5; total dissolved solids from 142 up to 193 mg/L; specific electrical conductivity from 284 up to 386 μS/cm; salinity from 0.14 up to 0.19 ppt. The received data for pH and total dissolved solids for water don’t exceed the values of maximum permissible concentration. Some peculiarities of the collected data are discussed in this paper.
