ASSESSMENT AND EVALUATION OF FLUORIDE CONCENTRATION IN GROUNDWATER OF PALNADU REGION: A MODEL STUDY

Water plays an important role in the world economy which is approximately 70% of the freshwater used by humans goes to agriculture. Safe drinking water is essential to humans and other life forms even though it provides no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack access to adequate sanitation. The concentration of fluorine in water causes several effects for human beings. In this study we deal with the effects that are caused by the high concentrations of fluorine in water and also suggests some preventive measures to be taken for decreasing the fluorine concentrations in water. Here we collected water samples of different regions and tested with the instrument namely Fluoride Electrode Instrument and identified the high fluoride concentrated area. Fluoride is added to public water supplies at an average concentration of about 1 part per million (1ppm) or 1 milligram per liter, or slightly below. Naturally occurring fluoride concentrations in surface waters depend on location but are generally low and usually do not exceed 0.3 ppm. The Highest fluoride level concentrations are recorded as 1.5mg/lit at the Jammalamadaka Panchayat of Macharla Mandal and Chinakodamagundla, Chintapalli Panchayats of Karempudi mandal.
