Bacteriological Analysis of Drinking Water Sources in CKNP Region of Gilgit –Baltistan, Pakistan

Abstract

The study was focused on the Bacteriological characteristics of drinking water within the selected villages fall in Central Karakoram National Park (CKNP) Gilgit-Baltistan, Pakistan. Different water sources were taken in to account including streams, springs, rivers and other storage structures viz; wells and Tanks. A total of 51 water samples were collected from 17 different localities and transported to lab in battery operated portable refrigerators. All necessary data including coordinates was mustered. Sources were examined with a strategy to sample from source mid and last points. The idea was to evaluate the stage and subsequent level of contamination. The level of contamination was ranged from 0-160 CFU for E-coli, 0-85 for Enterococci and total bacterial count ranged from 2-180 CFU, whereas no any Salmonella species was detected in one liter. The well and surface water was highly contaminated and the spring sources were less or no contaminated depending upon protected and open sources respectively. While the contamination level showed a culminated trend from mid to last usage points.
