Background: This research was conducted in the Karakoram Mountains of Northern Pakistan (Oshikhandass village) to investigate the level of pathogens presenting a public health hazard in typical sources of drinking water and their sensitivity pattern against seven antibiotics.

Methods: Nine months study included 216 representative water samples from heterogeneous sources were collected, including samples from main source, water reservoirs (I & II) and their distribution (tap water), household storage containers, water channels and water pits. Quantitative analysis of bacteria was performed by spread plate technique and antibiotic susceptibility test was done by disk diffusion method.

Results: Microbiologically, total fecal coliform in drinking water reflected an alarming health hazard i.e., in main source - 3.04×105 cfu/ml, followed by 3.68×105 cfu/ml in water reservoir-I, 3.90×105 cfu/ml in tap-I, 3.12×105 cfu/ml in water reservoir-II, 1.71×105 cfu/ml in tap-II, 3.42×105 cfu/ml in water container, 3.02×105 cfu/ml in water channel and 3.80×105 cfu/ml in water pit, respectively. The sensitivity test showed that Cefixime shows 77.77%, Ciprofloxacin 91.6%, Lincomycin 48.61%, Ampicillin 8.33%, Amoxicillin 16.66%, Cephradine 66.66%, and Tetracycline 29.16% against the isolated E.coli and Salmonella spp. shows 85.00% sensitivity against Cefixime followed by Ciprofloxacin 95.00%, Lincomycin 50.00%, Ampicillin 15.00%, Amoxicillin 25.00%, Cephradine 75.00% and Tetracycline 20.00%.

Conclusion: The resulting contamination of water sources with pathogens does not meet WHO Drinking Water Guidelines and their resistivity to antibiotics is an alarming threat to public health. So, there is a critical need for improvement in the water supply system and enhancement of public awareness on waterborne diseases.
