Background: As water is a basic and essential natural resource for all living things, this article addresses the vital need of analyzing its quality. The essay emphasizes the importance of water quality in public health by presenting perspectives from both developed and developing countries. A study was carried out at the biggest university of south-punjab “The Islamia University of Bahawalpur, Punjab, Pakistan”. The study covers an important knowledge deficit about Bahawalpur's water quality assessment, offers information to government agencies and academic institutions on WHO compliance, and suggests possible ways to improve the quality of drinking water.

Methodology: The multiple physical, chemical, and biological factors that go into evaluating water quality are highlighted in this article. In addition to the specific indicators evaluated, such as electrical conductivity, temperature, odor, transparency color,total dissolved solids (TDS) taste, total dissolved solids (TDS), pH, UV absorbance, total hardness, sulphates, and chlorides, the methodology section describes the technique used for sample collection and handling. Employing bacterial growth and Gram staining, biological factors were also examined.

Results: The outcomes of this research showed that different university campuses have varied water quality criteria. Especially, sample 2 (Abbasia Campus) had the highest concentration of electrical conductivity at 980 µS/cm; sample 2 also had the highest amount of TDS at 412 ppm; and sample 3 (Baghdad-ul-Jadeed Campus) had the highest level of bacterial contamination.

Conclusion: These parameters demonstrated concerning trends over time, with some of them surpassing acceptable levels. This article emphasizes the necessity of routine maintenance and examination of the water sources. In conclusion, this research contributes valuable insights into water quality assessment, with a specific focus on Bahawalpur, Pakistan. The findings underscore the importance of addressing water quality issues to safeguard public health and ensure access to clean and safe drinking water.
