Assessment of Groundwater Quality from Warana River Basin, Kolhapur District, Maharashtra, India

The present study was carried out in Warana River basin for the assessment of groundwater geochemistry. The study mainly focused on impact of intensive agricultural practices on groundwater regime of the study area. Methodology was adapted to know the local environmental components influencing the groundwater quality. Groundwater samples were collected from dug/bore wells during pre-monsoon and post-monsoon season and analyzed for physicochemical characteristics. The suitability of groundwater quality by collecting 65 representative samples from bore wells and dug wells covering in the rural areas of the Warana River Basin, Kolhapur District. Warana River Basin is situated in the northern side of the Kolhapur District. The groundwater from the study area have been classified for domestic and irrigation purpose on the basis of Sodium Absorption Ratio (SAR), Kelly’s Ratio (KR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Percent Sodium (% Na), Magnesium Hazard (MH), Magnesium Ratio (MR) and Permeability Index (PI). The values of majority of groundwater samples for SAR, KR, SSP, RSC, % Na, MH, MR and PI are within permissible limit indicating excellent quality for irrigation purpose.
