Evaluation of Drinking Water Quality in Pogradec District

Abstract

Supplying quality safe drinking water is a key factor for human health, a fundamental human right and an important component of effective health protection policies. In some regions of our country, investments in water supply and sanitation are lacking, affecting people's health. In this study, we have determined the quality of drinking water in Pogradec district, through organoleptic testing, physicochemical properties and bacteriological indicators, total coliforms and Escherichia coli. In this study are analyzed water samples, during each season of 2018, taken from Progrdec city and village piped system, in a natural recourse and private wells, which people use for water supply. Analyzes have been compared to drinking water rates according to the World Water Organization (WHO). The data obtained shows that the water supply in the city is clean and recommended for drinking and other personal needs. Organoleptic parameters are normal, physicochemical and bacteriological properties are in the limits recommended by WHO. Except in some cases where the parameters are not normal, there was a network fault, but immediate measures were taken to resolve the problem. In private wells, only one of the three was contaminated with total coliform and E. coli. This is because the well was not built under the right conditions. We recommend investing in the city and village water supply network and disinfecting them regularly. Also, private wells should be well maintained and disinfected. We also need to be careful with soil fertilization, because it affects groundwater pollution.
