Groundwater is found in vast quantities filling the spaces between grains of soil or rock. Water from rain and rivers migrates through the ground and is stored in soil and rocks. The present study was on the groundwaters of Ramachandrapuram S I and Serilingampally S II. In this paper, Total Alkalinity and Total Hardness were focussed. Alkalinity is an index of the buffering capacity of water. In the present work, Total Alkalinity average was 286 mg/l and 283mg/l at Station I, Ramachandrapuram and Station II, Serilingampally respectively. According to BIS ( 1983 ) and WHO ( 1984 ), the standard limit given is 0.6 – 1.2 mg/l and 1.5 mg/l respectively. At Station I, Total Alkalinity is 23.83 times more than BIS and 19.06 times more than WHO at Station I. Similarly at Station II, Total Alkalinity was 23.58 times more than BIS and 18.86 times more than WHO . Hence the groundwaters cannot be used for drinking purpose. Total Hardness is expressed in terms of lather produced while using soap. Soft water produces lather when we use soap whereas hard water precipitates. The Total Hardness average at Station I was 354 mg/l and 308 mg/l at Station II respectively. According to Glohmann and Wassers ( 1976 ), if the average Total Hardness value is 180 mg/l and above, they are classified as VERY HARD. Hence the groundwaters at Station I and Station II are VERY HARD. They cannot be used for drinking purpose. The study clearly indicated that the two groundwaters cannot be used for drinking purpose based on Total Alkalinity and Total Hardness.
