Online published on 3 May, 2025. Abstract This study test the water quality of 120 samples collected during 2019 to 2021 from Block Ellenabad, district Sirsa Haryana, regarding electrical conductivity (EC), carbonate ion (CO32-), bicarbonate ion (HCO3-), calcium and magnesium (Ca++ and Mg++), and residual sodium carbonate (RSC). The analysis revealed that most samples (50% on average) fell within the 0-2 dS/m EC range, indicating generally good water quality for irrigation. However, higher EC levels (2-8 dSm-1) were present, necessitating careful water management, including mixing with canal water to mitigate potential adverse effects on crops. The study also observed variability in CO32- concentrations with a trend toward increasing levels over time particularly in 2021. Bicarbonate concentrations were predominantly in the 4-6 meL-1 range, but higher levels (>8 meL-1) increased in 2021, raising concerns about rising alkalinity. The Ca++ and Mg++ concentrations were mostly within the lower range (0-8 meL-1), but higher concentrations became more prevalent in 2021, indicating a potential increase in mineral content in the water. RSC values, crucial for determining water's suitability for irrigation, showed that 58.18% of samples had values between 2.5 and 4.5 meL-1, suggesting moderate to severe restrictions on their use. The study underscored the importance of regular monitoring and management practices to ensure sustainable agricultural practices in regions where water quality may be compromised.
