ABSTRACT

 

Construction of several dams and weirs on Pravara river, drains Sangamner area located in the northern part of Ahmednagar district of Maharashtra, India, results into rapid development of agro-industries. Effect of large agro-industrial development leads to overuse of irrigation, resulted into deterioration of quality of groundwater and soil of the study area. In the present study, attempt was made to assess the groundwater quality by analyzing 84 groundwater samples collected along the recharge to discharge zone of Pravara river basin. All the samples were analyzed for pH, EC, TDS, Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, SO42-, NO3-, PO43-, SiO2 and Boron. Chemical characteristics of groundwater was dominated by Ca+Mg > Na+K-HCO3+CO3 hydro-chemical types followed by Na+K-HCO3+CO3 and Na+K-SO4+Cl+NO3, indicating dominance of cation and anion exchange process on both spatial as well as temporal scales. Diverse hydro-chemical characteristics were studied by plotting Piper
