Microbiological quality assessment of drinking water in three selected areas of district Mansehra
Abstract
Water has a great importance in our life, primary used for drinking purpose but due to microbial contamination, it becomes unfit for drinking. The present study was conducted to examine the bacterial contamination and its count in three water sources i.e. wells, tube wells and hand pumps in three selected areas of district Mansehra, i.e. Mansehra city, Union Council Dhodial and Union Council Shinkiari. A total of 64 samples of water were analyzed for Total Plate Count (TPC), Coliform, Fecal coliform and E. coli. Techniques like multiple tube fermentation, total plate count and latex test reagent kit was used for bacterial conformation. (45/64) water samples were analyzed from the wells of Mansehra city, Union Council Dhodial and Union Council Shinkiari. Only four and three water samples were analyzed for bacterial load from tube wells water of Mansehra city and Union Council Dhodial. From hand pump water three, four and five samples (total 12) were examined from Union Council Dhodial, Mansehra city and Union Council Shinkiari respectively. The samples were analyzed for microbial parameters and found that more than 70% water samples were contaminated with fecal coliform including Escherichia. coli. Present study indicates that there is lack of cent per cent purity in any water source from study area i.e. Mansehra district. Hence it is concluded that the water in study areas was contaminated and unfit for drinking purposes according to Pakistan standards.
