Comparative Analysis of Some Indicators of Water Quality in the Territory of
Neftchala Region
Abstract
The presented article is dedicated to the determination of organoleptic and some chemical
indicators of drinking water samples taken from the territory of Neftchala region and comparison of
the obtained results with normative documents. Waters samples were taken from 5 points and
delivered to the Hygiene laboratory of the Scientific Research Institute of Medical Prevention named
after V.Y.Akhundova.
The smell and taste of water samples were determined by comparison with a 5-point scale at the
place where the samples were taken in accordance with the rules established in the state standards.
During the chemical study, its pH, total hardness, chloride ions and residual chlorine were determined.
The results of the research showed that the smell and taste of water, as well as its chemical
indicators (pH 7,3±0,23-7,8±0,21, total hardness 6,4±0,23-6,8±0,24 mgekv/dm3, removable hardness
2,2±0,06-3,0±0,08mgekv/dm3, chloride ions 80,0±3,79-98,0±4,32mg/dm3, residual chlorine 0,12-
0,18mg/dm3) is in accordance with sanitary rules and norms.
Keywords: water, organoleptic characteristics, total hardness, chloride ions, residual chlorine
