Pre- and Post-Monsoon variation in Physico-Chemical characteristics in Groundwater quality of parts of Tirunelveli District, Tamil Nadu, India

摘要

A total of 43 groundwater samples for three representative seasons were collected from parts of Tirunelveli district of Tamilnadu, India to decipher hydrogeochemistry and groundwater quality for determining its suitability for drinking and agricultural proposes.The water is neutral to alkaline in nature with pH ranging from 7.1 to 8.6 with an average of 7.8 pre monsoon and 7.7 post monsoon. The abundance of major ions in the groundwater was in the order of Na Ca Mg Na+K Cl SO4 TDS TH. ?As per the classification of water for irrigation purpose, water is fit for domestic and agricultural purposes with minor exceptions irrespective of seasons.
