Abstract
Water borne diseases continue to be a dominant cause of water borne morbidities and mortality all over the world. Hence, drinking water needs to be protected from pollution and biological contamination. Ground water samples were collected from ten different sampling point in Rajajinagar area of Bangalore and analysed for water quality parameters viz. pH, total alkalinity, chloride, total dissolved solids, electrical conductivity, sodium, potassium, calcium, magnesium, dissolved oxygen, BOD, COD and total hardness. The pH value of the study area ranges between 7.3 to 8.4 indicating that ground water is slightly alkaline. The total alkalinity are varied in the range from 122 to 282 mg/l which is well within the limit prescribed by BIS. The TDS value found from 397 to 546 mg/l. The values of hardness of water ranges from 125 to 267 mg/l which is within the prescribed limit as per BIS.

Water is the most essential component for all living things
Ground water quality is usually characterized by different physico-chemical characteristics.These parameters varies widely due to the various types of pollution, seasonal fluctuation and groundwater extraction[4]
Ground water samples were collected from 10 different sampling point
Summary
Water is the most essential component for all living things. Living things cannot survive without water. Underground water is clean but it depends upon quality and quantity of materials dispersed and dissolved in it[2]. The reason for contamination and pollution of water in the surroundings and in the storage are pesticides, fertilizers, industrial wastes[2]. The physico-chemical contaminants that adversely affect the quality of groundwater may be arises from a variety of sources, including land application of agricultural chemicals and organic wastes, infiltration of irrigation water, septic tanks[3]. Ground water quality is usually characterized by different physico-chemical characteristics.These parameters varies widely due to the various types of pollution, seasonal fluctuation and groundwater extraction[4]
