To study the physico-chemical properties and bacteriological examination of stepwell water from majhwar region in distt. mandi of himachal pradesh, india

Water is basic and vital resource on earth. Due to increase in population, industrialization and pollution, water has became polluted. In this study, physico-chemical properties and bacteriological examination of stepwell water from Majhwar region in Distt. Mandi of Himachal Pradesh, India was done. Among the physico-chemical analysis, Total Dissolved Soilds (TDS), Disssolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Alkalinity, Hardness, Chloride and pH were checked. Bacteriological analysis was made by multiple tube fermentation test which include: Presumptive coliform test, confirmed coliform test and completed coliform test. All the physico-chemical parameters were compared with WHO standard and it was found that water was potable.
