Contaminated groundwater is common problem in drinking water systems. Water system arerequired safe and purified for drinking water.coliform bacteria are organisms commonly found in water, soil and plants. In this study, Six water samples of ground water were collected from different areas of Vadodara. In these Six samples two samples were higher MPN number. The MPN test was used for screening method to detect coliform contamination. The primary water quality analysis for physico -chemical parameters indicate variation of samples. All samples pH values were varying between 6.28 to 8.71 which signifies the basic range of pH. The turbidity values of water sample were between 0.7 NTU to 2.4 NTU. TDS higher concentration observed in between 112 mg/liter to 522 mg/liter. pH , Alkalinity , Calcium , Magnesium , Nitratewere below the permissible limit but the water sample concentration of Chloride and Turbidity were higher than the permissible limit. Therefore the primary indication was threatful in case of drinking water quality.
