Abstract

Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). In other words, water pollution can be defined as the contamination of water bodies, i.e. lakes, rivers, oceans etc. that occurs due to direct or indirect discharge of pollutants in to the water bodies. It has been suggested that it is the leading worldwide cause of deaths and diseases and that it accounts for the deaths of more than 14,000 people daily. Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. In this context four different samples designated as S1, S2, S3 and S4 were taken for chemical and bacteriological examination. The collection site of the four different samples were Barachhak village, Kalyanpur Housing, Ghagarburi Temple and Kalipahari Village. After chemical and bacteriological examination it was estimated that all the samples were contaminated and their parameters were higher than safe limit.
