The present paper aims at determining the water quality of Groundwater by analyzingthe physico-chemical characteristics and assessment of Water quality index (WQI) of Madhurawada region, Visakhapatnam city. Total of 30 samples were collected during the year 2018 and 2019 in pre and post monsoon respectively. The physico-chemical parameters include pH, Conductivity, Total Dissolved Solids, Total Suspended Solids, Alkalinity, Turbidity, Total Hardness, Calcium, Magnesium, Chlorides, DO and BOD. Results showed that most of the parameters were exceeded the recommended ground water quality levels of Bureau of Indian Standards (BIS). The computed WaterQuality Index (WQI) values ranges from 62.92 to 123.97 and thereforecan be categorized into “Poor water” to “water unsuitable for drinking.” Of the all groundwater samples collected and calculated 7% of samples fall under “poor water quality”, 54% samples fall under “very poor water quality” andunfortunately, 40% of the samples represent water “unsuitable for drinking purposes.Results obtained from the analyses showed that, pH are slightly alkaline in nature with ranges from 6.84–7.99 and Total hardness ranges from 235–585mg/l. pH is observed high at Chandrampalem ZPH School, APHB Kommadi and Carpenters Colony.Total Hardness values are above the permissible limits at Shilparamam, VambayColony and Dmart area. Total Dissolved Solids ranges from 350 to 1060 mg/l. TDS values are above the permissible limits in at DMart Area, NGO Layout and APHB Kommadi. Chlorides and Electrical Conductivity values are also above permissible limits. Chloride values are above the permissible limits at Chandrampalem ZPH School.Results revealed that ground water is getting polluted day by day due to Urbanization and Industrialization activities and treatment of groundwater is recommended before consumption.
