Chemical analysis of groundwater for a region is very important to the irrigation engineers and policy makers for site specific management of this important natural resource. Therefore, a study was planned to work out the chemical composition (Na+, Ca2+, Mg2+, K+, CO32-, HCO3-, Cl-, SO42-) and other quality parameters (pH, EC, SAR and RSC) of groundwater (117 samples) for Ellenbad block of Sirsa district, Haryana. Sodium and chloride were found as major anion and cation, respectively, in the groundwater samples. Through this chemical analysis, the groundwater quality of the block was interpreted according to three different classification criteria i.e. AICRP, USSL and Piper to check its suitability for irrigation purpose. To study the spatial distribution of different parameters (EC, pH and water quality according to AICRP criteria), thematic maps were generated using inverse distance technique in geographic information system. According to AICRP criteria, out of seven categories, maximum 44.4 % of samples were found in good and minimum 6.8 % were found in saline as well as in marginally alkali categories. According to USSL criteria, groundwater quality of the block was observed under C2S1, C3S1, C3S2, C4S2, C3S3, C4S3 and C4S4 categories. According to Piper criteria, 25.6 % samples was under good category (Ca2+-Mg2+-Cl- and Ca2+-Na+-HCO3- type) suitable for irrigation and 74.4 % was under poor category (Na+-Cl- type) unsuitable for irrigation. © 2017, Chemical Publishing Co.
