Water is one of the most vital and valuable natural resource in universe. The completion of lifecycle of human, animal, plants and microorganisms is impossible without the use of water. Worldwide, the contaminated surface and groundwater with heavy metals and microbes, severely affect the lifecycle of the said organisms. Therefore, the use of safe and pure water is necessary. People of Balochistan province mainly use spring and open well water for agriculture and drinking purposes. To know the microbial and heavy metals status of the water of district Ziarat Balochistan. Microbes, heavy metals, and physiochemical characteristics of drinking water of various sources of Choutair village District Ziarat (Balochistan) were. Total 27 samples were collected from spring, open and tube well. Each from Choutair, Ziarat, and Tandwani villages of District Ziarat (Baluchistan). Alarming results were regarding the colony of coliform in all tested water samples with the range between 2.32 to 19.33 MPN/100ml (more than acceptable range (0 CFU) of World Health Organization (WHO). While the E. coli range was 2.00 to 2.33 MPN/100 ml, found only in spring water more than the permissible range of WHO. Cadmium (Cd) and lead (Pb) were determined by using Atomic Absorption Spectrophotometer. Cadmium was slightly higher than the permissible range of WHO. While the lead was within the range set by WHO. Physicochemical parameters i.e. pH, Electrical conductivity (EC), Total dissolved solid (TDS) and Turbidity were ranged in the permissible standard set by WHO. These results concludes that the excessive amount of Coliform and Cadmium in drinking water of this area is not safe for human consumption, restaurants, and food industries. Government should install treatment plants to make water free from microbiological and physiochemical contamination.
