Assessment of Drinking Water Samples of Different Localities in Fier District

Abstract

This research aims to evaluate the quality of drinking water in 13 rural administrative units of Fier district and compare the results with WHO standards, in order to ensure the supply of clean drinking water. This study was carried out to give a complete view regarding water quality in rural areas of Fier and to identify issues that may affect public health. The monitoring process of the standards will be made by microbiological (Escherichia coli, Streptococcus faecalis and Clostridium perfrigens) and physical chemical(NH4+ mg/l, NO2 - mg/l, Cl - mg/l and pH) indicators. The samples are collected every month, from January 2014 until February 2015, in different locations scattered in 13 different administrative units. Study and analyzing all the data and comparing them in order to see the trend of the pollution level of the drinking water, and the number of positive cases with faecal indicators. MPN index is used for evaluation of Escherichia coli, while the number of heterotrophic bacteria is determined by counting colonies on plates with PCA. Our results show that the physical and chemical quality of the water is at line with WHO standards. The majority of drinking water samples are free from contamination with faecal indicator, but 5.7 % of the samples were found positive with at least on microbiological indicator E.coli, 3% of samples were found positive for 3 faecal indicator Escherichia coli, Streptococcus faecalis and Clostridium perfrigens.
