Hydrogeochemistry for the assessment of groundwater quality for irrigation purpose in and around Lakkireddypalli, Cuddapah Dist, Andhra Pradesh

Abstract

Hydrogeochemical characteristics and quality of groundwater in around Lakkireddypalli area of Cuddapah District, Andhra Pradesh have been evaluated based on different indices for assessing groundwater for irrigation purpose. Groundwater samples were collected and analyzed for physiochemical parameters and major ions. The suitability of groundwater of the study area for irrigation is determined using different factors like Sodium percentage, Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP), Kelley’s Ratio (KR), and Magnesium Ratio (MR).The results revealed that the groundwater is alkaline in nature. Irrigation water quality indicators like SAR, Na%, SSP, KR, RAC and MR reveal that the groundwater is suitable for irrigation purposes with few exceptions. As per the SAR classification all groundwater samples fall under safe category. The interpretation on the basis of available data has shown that the groundwater of the study area is suitable for irrigation purpose.
