Abstract
This dataset paper aimed to analyse the quality of groundwater of Yamunanagar and Ambala districts in North-Eastern Haryana, India rooted on the various analytical elements and hydro-chemical parameters. Also, Piper and Gibbs diagram were applied to observe hydro-chemical characteristics and controlling constituents of the underground aqua region. The impendence of anions was noted to be tolerable in 93.33% of the spots while 86.67% groundwater samples were observed to be in the desirable limit for cations. The analytical constituents of TH, TA, TDS, and pH were reported to be tolerable in 76.66%, 80%, 60%, and 100% of the water-samples, respectively. Eight water-sampling spots manifested unacceptable ranges of one or more of the physico-chemical constituents. Seven spots were observed to be suffering from one constituent and therefore were classified to be falling in the 'Grey-Zone'. One location (i.e. 23) has been found to be severely influenced by excess of TH, TA, TDS, SO(4) (2-), and Ca(2+) and is reported to be falling in the 'Red-Zone'. The classification of groundwater based on Piper diagram depicted that pre-dominant type of sub-surface water hydro-chemical facies of area was 'Ca- Mg- HCO(3)-Cl('). Gibb's figure revealed that underground water pre-eminence distribution is probably resulted by water-rock dominance in sub-surface water.
