Deterioration in the quality of water used for irrigation is a matter of concern in recent years. Indiscriminate use of chemical fertilizers resulting in water quality deterioration is not new. In the present study, the water samples received from farmers for advisory purpose for irrigation were analysed for 10 important parameters from 2000 to 2012. Eight hundred and three water samples were analysed and assessed for the possible changes in water quality parameters
over a period of time.
