Abstract
Groundwater is almost globally important for human consumption as well as for the support of habitat and for maintaining the quality of base flow to rivers, while its quality assessment is essential to ensure sustainable safe use of the resources for drinking, agricultural, and industrial purposes. Forty five groundwater samples were collected pre and post-monsoon seasons around Choutuppal area after collection of the all the samples are asses the groundwater quality and investigate hydrochemistry nature by analysis of major cations (Ca2+, Mg2+, Na+, K+) and anions (HCO−3, Cl−, F−, So4−2, NO3- ) besides some physical and chemical parameters (pH, electrical conductivity and Total hardness). Also, geographic information system-based groundwater quality mapping in the form of visually communicating contour maps was developed to delineate spatial variation in physico-chemical characteristics of groundwater samples. Piper Trilinear diagram was constructed to identify groundwater groups (hydrochemical facies) using major anionic and cationic concentration and it was found that majority of the samples belongs to Ca2+–Mg2+– Cl—SO4-2 and Ca2+–Mg2+–HCO−3 hydrochemical facies. Wilcox classification and US Salinity Laboratory hazard diagram suggests that 92.86% of the samples were falling under good to permissible category and C3–S1 groups, respectively, indicating high salinity/low sodium.
