Water pollution due to chemicals and microbes is one of the serious environmental problems, which has greatly impacted human health. Recorded history of contaminated drinking water supply has witnessed various viral, bacterial and protozoan diseases, globally. It is estimated that >250 million cases of waterborne diseases are reported worldwide and over 25 million deaths are blamed due to waterborne-diseases. Pakistan has been facing the same problem due to improper water management, obsolete distribution infrastructure, bad sanitary condition and poor drinking water quality. An estimated 70% Pakistani population living in rural areas have no access to potable water distribution system, whereas in urban areas, between 40-60% urban population has access to safe and clean drinking
of "microbiological analysis of drinking water and the water supply system in the city of Peshawar this study objective is to study the physical, chemical and bacteriological analysis of drinking water by examining Ph. Soluble solids, turbidity coliform culture phenotypes coliform and e. coli. The study found that the pH value is in the range that is acceptable betweenpH (6.65-7.91), turbidity (3-9NTU) and TSS (2-6 mg/L). of 10 bacterial adjuvant areas found that samples from ponds to provide results. Coliform positive. Coliform positive culture phenotypes 6 samples of drinking water from
distribution system were fecal coliform positive and 4 samples indicate that drinking water is highly
vulnerable to bacterial contamination. Water
