All organisms, including humans, require water to survive on a global scale. Because of this, it is crucial for life to have access to adequate water supplies. Scientists and public health organizations are growing more concerned about bacterial pollution of surface waterways because pathogenic microorganisms can have detrimental impacts on human health. In this article, the regional and seasonal variability of faecal coliform bacteria (FCB) concentrations was examined. The purpose of this article was to assess the microbial quality of the drinking water supplied in Quetta city, Balochistan. The distribution of water at the surface was examined using various standard techniques, and the results indicated successful bacterial isolation. The conclusions showed that coliform group (Klebsiella sp., Citrobacter sp., Enteriobacter sp.), and fecal coliform (E. coli) were identified. Seasonal and geographic differences in the types, numbers, and quality of isolated bacteria were assessed and addressed.
The evaluation of coliform bacteria from cow dung and drinking water in Quetta, Balochistan, has only received a little amount of attention thus far. So, while working on a new project, think about evaluating the coliform bacteria in cattle and drinking water. The number of potential pathogens is vast, and pathogen concentrations from faecal contamination are frequently low. As a result, it is impractical to analyze each water sample for pathogens. In contrast, the detection of pathogens is done indirectly by looking for "indicator" organisms like coliform bacteria. Data from one-year assessments of the microbiological quality of various faecal coliform species in drinking water and animal waste were obtained for this study from urban, rural, and private sources in Quetta. 50 samples in all, 25 from drinking water and 25 from animal waste were collected. The results indicated that faecal coliform, Escherichia coli (22,3%), and Klebsiella (2%), respectively, were the most and least common bacteria in urban water supplies. In private sources, E. coli (34%) and Klebsiella (1.3%) were the most and least prevalent, respectively, followed by E. coli (45.9%) and Enterobacter (2.6%) in rural water sources.
In conclusion, the results of this research demonstrate that all water samples were contaminated with total and faecal coliform bacteria, typically with large numbers of colonies, which poses a serious danger of waterborne illnesses for the general public, especially young children.
