Evaluating groundwater for changes in chemical and microbial profiles after recharging with treated wastewater

Aquifer recharge with effluent wastewater (EWW) is a strategy that Saudi Arabia will implement to restore the groundwater supply. Hence monitoring the quality of the groundwater is essential because majority of these recharged waters will be used for food production. The aim of this study is to provide a baseline knowledge on the groundwater quality in Wadi Fatimah during recharge with EWW from the chemical and microbial perspective. We found that recharging aquifer with EWW did not affect the quality of the groundwater during 2016.
