Abstract: This study was performed to understand the impact of groundwater quality on the crop yields and its suitability for the irrigation. The hydrogeochemical assessment indicates chemical weathering is prevalent in the aquifer system. Low sodium-hazard observed in almost all samples. High salinity-hazard observed in the shallow aquifer indicates leaching of contaminants from the surface. Salinity-hazard statistics indicates ∼27.60% groundwater suitable for irrigation, ∼47.65% groundwater considerable for irrigation of selected crops whose salinity tolerance limit is high, ∼13.44% groundwater (fresh-brackish) cause problem in the soil and ∼11.31% groundwater unsuitable for the irrigation.
