Hydrogeochemical Characterization and Evaluation of Groundwater Quality in Anumula Province of Semiarid Region, Telangana State, India

Abstract

The objective of the work is to hydrochemical characterisation and evaluation of groundwater quality    in Anumula province of Nalgonda district of Telangana state. The province, which spans 192 km 2 and is located in a semiarid environment with water scarcity and groundwater quality issues. In the year 2018, groundwater samples were collected at 47 stations and were analysed for their chemical composi tion. Based on hydro-chemical facies depicted through a piper diagram that Ca-Mg-HCO3 type of water predominates in the study area. The major ion data showing that groundwater is contaminated with fluoride (27.6%) and nitrate (21.2%) of samples have b eyond the permissible limits of WHO recommended values for drinking purpose. The data of USSL diagram, residua l sodium carbonate, sodium adsorption ratio, salinity hazard and sodium percent depict that the groundwater is suitability of water for irrigation use in the region. This study further indicating that groundwater should be treated before use for drinking while for irrigation purpose it can be used with due attention.
