Abstract: Groundwater, the main source of irrigation, drinking or domestic purposes, is affected due to exponential growth of population, urbanization, industrialization and agricultural revolution. Groundwater qualityis also affected due to discharge of poor quality water from various industries and urban waste water to the natural water courses. An intensive survey was conducted to assess the quality of groundwater for irrigation purpose in Rajaund block of Kaithal district by focusing on physico-chemical parameters. In total, fifty nine samples of groundwater were collected randomly from running tubewells. Analysis of water samples revealed that 37.20 %, 32.30% and 30.50% samples were good, alkali and saline in nature, respectively. The average pH of water samples was 7.97 with a range of 7.04-8.89. Electrical conductivity of water varied from 0.66 to 8.25 dSm^-1 with mean value of 2.40 dSm^-1. The analysis further revealed that order of abundance of cations in water samples was Na⁺ > Mg²⁺ > Ca²⁺ >K⁺, while that of anions was Cl^- > SO₄^2- > HCO₃^- >CO₃^2- > NO₃^-.
