Biochemical and microbiological evaluation of the water samples collected from different areas of district Kohat and Mohamand Agency, Pakistan.
Abstract
Contamination of drinking water sources mainly due to microorganisms is the major problem in many areas of Pakistan. Pakistan is also facing the problem of contamination of drinking water which greatly affects human health and quality of life. The most important component of human beings for living is water. Therefore, it is important to analyze drinking water quality mostly in developing countries as the local people are mostly unaware of the water pollution. In this study, twenty three samples of water were analyzed during a 3-month period from the well and lake water supplies of different areas of Kohat and Mohamand Agency. The bacteriological evaluation was done and several tests were performed such as Total Plate Count, Coliform, Feacal coliform, Escherichia coli (E. coli) and Biochemical test. In this study, thirteen samples were in the normal range and 10 samples were out of safety ranges fixed by World Health Organization (WHO). The water which was not fit for drinking can be a consistent risk of the infectious diseases and continuous assessment and purification strategies should be developed in these areas to reduce the microbial contamination. The proper training by the local public authorities is required to educate the local community about water pollution, their causes and preventive measures in order to improve the health status of the people in the regions.
