Abstract

Ground water contamination has become a major concern in recent years. Hard water is considered aprimary cause of many health-relating issues due to its unsuitability for drinking, domestic, industrial and agriculturalpurposes. Current studies were performed to explore the degree of hardness in drinking water of the selected areas ofVehari city, Pakistan. For this purpose, ten water samples were collected and analyzed. This research involves presentpractices and easy approaches to evaluate the quality of drinking water. The tested samples have shown pH 7.3-7.7,temperature 27-320C and TDS value of 545-1155 mg/L. The hardness of tested water samples was found in the rangeof 110-530 mg/L by titration method. The soap solution method demonstrated the degree of hardness (dᵒTH) in therange of 19.8-35.41. The obtained results were compared with the national and international standards worldwide. Thedrinking water of investigated areas was found hard, contaminated and unsuitable.
