Hydrochemical processes governing groundwater quality of sedimentary aquifers in Central Saudi Arabia and its environmental implications

The present study deals with the interpretation of the major processes governing the groundwater chemistry in parts of Qassim and Riyadh province of Saudi Arabia. The study area that is dominated by agricultural activities is represented by a multi-layered aquifer system with sedimentary formations ranging from Cambrian to the Quaternary present as outcrops. Groundwater samples from 97 agricultural bore wells in the area were collected and...
