ANALYSIS OF GROUND WATER COLLECTED FROM IN AND AROUND MADALAVARIGUDEM, KRISHNA DIST, ANDHRA PRADESH, INDIA

Water is an essential natural resource for sustaining life and environment but over the last few decades the water quality is deteriorating due to it’s over exploitation. Water quality is essential parameter to be studied when the overall focus is sustainable development keeping mankind at focal point. Groundwater is the major source of drinking water in rural as well as in urban areas and over 94% of the drinking water demand is met by groundwater. The study was carried out to assess the ground water quality and its suitability for drinking purpose in most rural habitations of ground water in Madalavarigudem, Andhra Pradesh, India. For this purpose, 3 water samples collected from hand pumps and bore wells of village of study area were analyzed for different physico-chemical parameters such as pH, total alkalinity, acidity and total dissolved solids. The pH value in the study area found from 7.2 to 8.3. Total alkalinity will be 730 to 980 mg/L. Total acidity will be 21 to 35 while value of TDS ranges from 150 to 250mg/L. The study reveals that almost all parameters were exceeding the permissible limits. As per the desirable and maximum permissible limit for total dissolved solids, acidity and alkalinity, determined by WHO BIS and ICMR standards, the groundwater sources are unfit for drinking purposes respectively. Due to the higher in drinking water several cases of dental and skeletal fluorosis have appeared in this region. After evaluating the data of this study, it is concluded that drinking water of Madalavarigudem is not potable and there is an instant need to take ameliorative steps in this region to prevent the population from adverse health effects.
