Abstract

Reconnaissance on the suitability of groundwater quality for irrigation in Tubinakere industrial area, Mandya district, Karnataka was done by determining ion exchange, potential salinity, Cl-/HCO3- ratio, magnesium hazard, percentage sodium, Kelley’s ratio and Residual Sodium Bi-Carbonate (RSBC). 94% of the samples are positive in case of both cation exchange indices leading to reverse ion exchange, potential salinity is slightly high making groundwater samples unfit for irrigation purpose. 75% of samples are slightly to moderately affected on the basis of Cl-/HCO3- ratio. Two of samples falls in unsuitable category with Magnesium Hazard >50%. Based on the classification of percentage sodium, maximum of samples falls under excellent, good waters and 87% of samples were suitable for irrigation as per Kelley’s ratio. RSBC values were <5meq/L safe for irrigation purposes. The study stated that water quality hazards of potential salinity and ratio of Cl-/HCO3- values indicates that groundwater samples are not suitable for irrigation.

Keywords: Industrial effluent, irrigation, sodium, impact.
