Relating wellfield drawdown and water quality to aquifer sustainability – A method for assessing safe groundwater abstraction

Planning for sustainable groundwater abstraction requires realistic and reliable assessments of groundwater drawdown in aquifers as well as impacted groundwater-dependent terrestrial and aquatic ecosystems. Present-day impact assessments allocate water for the environment and ecosystems in the form of environmental groundwater requirements (EGWRs). However, securing sustainable groundwater abstraction also requires stable groundwater quality for...
