Abstract :

Groundwater is the world‘s largest accessible freshwater and important resource for drinking water supply, irrigation and industrial purposes as well as for global food security. Approximately one-third of the world�s population depends on groundwater for drinking purpose. Geology of an area, the degree of chemical weathering of various rock types and anthropogenic factors affect the chemistry of groundwater. Drinking water is an important resource that needs to be protected from pollution and biological contamination. Water is vital to health, well-being, food security and socioeconomic development of mankind. Underground water is clean but it depends upon quality and quantity of minerals dispersed and dissolved in it. Therefore, the presence of contaminants in natural fresh water continues to be one of the most important environmental issues in many areas of the world, particularly in developing countries where several communities are far away from potable water supply. Low- income communities, which rely on untreated surface water and groundwater supplies for domestic and agricultural uses are the most exposed to the impact of poor water quality. The aim of this study is to conduct an assessment of the Geohydrological and Hydrogeochemical Studies of Veerapunayunipalle Mandal, YSR Kadapa District, Andhra Pradesh. The proposed study area in the Veerapunayunipalle Mandal of YSR Kadapa District and is shown in the figure 1. The study area falls in the survey of India Toposheet No: 57 J/06 and J/11 on 1:50,000 scale. Twenty two samples of ground water using for drinking and agricultural purpose were collected from either hand pumps or open wells at different villages of Veerapunayunipalle Mandal of YSR Kadapa District, during the summer season month of January 2019. The pH of ground water in the study area is ranging from 7.7 to 8.9. The total hardness of the groundwater in the study area is ranging from 159 to 878 mg/l. Water hardness is primarily due to the result of interaction between water and the Geological formation. The calcium concentration of Groundwater in the study area is ranging from 12 to 164 mg/l during the post-monsoon period. The chloride concentration of the ground water in the study area ranging from 106 to 8734 mg/l during post-monsoon period. The bicarbonate concentration of the groundwater in the study area is ranging from 61 to 195 mg/l during the post-monsoon period.
