Abstract:
This paper is an attempt to analyze the water quality of Rajahmundry division of East Godavari district of Andhra Pradesh in South India for irrigation purpose. Therefore, 79 groundwater samples were collected from this area to assess their quality and suitability for irrigation purposes over a period of pre and post-monsoon seasons (kharif and Rabi, 2017-2018). The groundwater samples were analyzed for pH, electrical conductivity (EC), sodium adsorption ratio (SAR) and residual sodium carbonate (RSC). Study of all these characteristics indicates that groundwater in pre-monsoon (kharif) season is slightly suitable for irrigation purpose compared to post-monsoon season because of high values of EC and salinity.
