Chemical and microbiological assessment of drinking water quality

Abstract

Background: Access to an adequate amount of water is restricted because of the increase in the use of natural resources, which is caused by the rapid growing in world population and the climate change that global warming brings, and the development in the industry. Investigating the causes of water pollution, creating solutions for the problem, taking the control of the pollution, and maintaining monitorability are necessary.Objectives: This study was carried out in order to determine microbiological and chemical characteristics of drinking water and their compatibility for human consumption with the aim of providing safety of drinking waters.Methods: Thirty-four drinking water samples obtained from different sampling points in Ankara, Turkey, in 2019 were subjected to microbiological analysis and chemical analysis in terms of anions (bromide-Br-, chloride-Cl-, fluoride-F-, nitrate-NO3-, nitrite-NO2-, sulfate-SO4-2) by ion chromatography. Microbiological analyses were applied according to the international standards.Results: None of the samples contained coliform bacteria, Escherichia coli and intestinal enterococci. It was established that concentrations of the specified anions in tested waters were within the acceptable levels of with the Council Directive 98/83/EC.Conclusions: The determined chemical and microbiological qualities of these samples are suitable for drinking, and do not poseany threats to public health.Keywords: Drinking water; analysis; chemical; microbiological; quality.

“…The infectious disease theme continues with papers 55 – 63 on COVID-19 and other infections 64 – 69 . While we rightly put emphasis on infectious diseases, there is light at the end of the tunnel regarding the Ebola out break in Uganda: the country has spent about 3 weeks without any new cases of Ebola.…”
