Aquifer storage and recovery (ASR) is an effective method of recharging reclaimed or surplus surface water into confined or semi-confined permeable formations for later extraction. A key factor in the long-term viability of ASR is the extent of mineral interaction between two dissimilar water types, their recoverable fractions and consequent impact on water quality and aquifer stability.
