Underground water is one of the most important resources for plant growth and development. Determination underground water quality is important tool observe the suitability of water for use a particular area. An investigation was carried out to assessment of hydro-chemical properties of underground water quality in part of Jodhpur district, Rajasthan and 182 sites from 88 villages of 6 tehsils of south eastern part of district were collected during December 2021 and analysed for hydro chemical behavior. Among different cations, the order of dominance of different cations was Na+, Mg2+, Ca2+ and K+ and average content of these cations was 27.89, 9.05, 5.45 and 0.31 me L-1, respectively. The mean anion content of south part of Jodhpur was 24.51, 12.14, 5.28 and 1.26 for Cl-, HCO3-, SO4-2 and CO3-2, respectively. Mostly water quality parameter like good, marginally saline and high SAR saline depends on theses cation and anion ion.

Underground water, Cations, Anions, Jodhpur region

In various degrees, all of the water contains dissolved salts. When salts dissolve in water, they are divided into ions (cations and anions). In irrigation water, the main cations are calcium, magnesium, sodium, and potassium, and its anions are carbonate, bicarbonate, chloride, and sulphate. In general, sodium was found to be the most abundant cation in all irrigation water samples in the south-eastern parts of Jodhpur, followed by magnesium, calcium, and potassium. Chloride was shown to be the leading anion among anions, followed by bicarbonate, sulphate, and carbonate.
