Abstract


Groundwater constitutes an important source of water for drinking, agriculture and industrial production. The use of groundwater has increased significantly in the last decades due to its widespread occurrence and overall good quality. A total of 28 drinking water samples collected from different locations of Kalasapadu, Porumamilla Mandals, Kadapa District Andhra Pradesh, and India were analysed for water quality parameters such as pH, electrical conductivity, total dissolved solids, total alkalinity, total hardness, fluoride, bicarbonates, calcium, magnesium and chloride. The results obtained were found to exceed the permissible limits. It is observed that most of the groundwater is alkaline in nature. The Total Dissolved Solids of the groundwater in the study area is ranging from 510 mg/l to 1698 mg/l. The Total hardness of the groundwater in the study area is ranging from 70 to 290 mg/l. Groundwater of the study area is very hard. The calcium concentration of the groundwater in the study area is ranging from 10 mg/l to 88 mg/l. The Mg concentration of the groundwater in the study area is ranging from 11 mg/l to 89 mg/l. The chloride concentration of the groundwater in the study area is ranging from 21.3 to 146 mg/l during pre-monsoon period. The bicarbonate concentration of the groundwater in the study area is ranging from 97.6 mg/l to 239 mg/l during pre-monsoon period. The fluoride concentration of the groundwater in the study area is ranging from 0.399 mg/l to 2.88 mg/l during premonsoon period. Low concentration of fluoride (0.399 mg/l) is observed in Yellayapalli village and high concentration of fluoride (2.88 mg/l) is observed in the village Pondugarupalli. Dental and skeletal fluorosis and deformation of bones in children as well as adults were observed in the study area indicating the health impact of fluoride in groundwater. Probable sources of fluoride are weathering and leaching of fluoride bearingminerals under the alkaline environment. Proper defluoridation techniques have to be followed to monitor fluoride contamination.
