New method for monitoring groundwater recharge 💡
Artificial groundwater recharge is one way of preparing for increasingly frequent dry spells. The length of time the water spends in the ground between infiltration and extraction is crucial to its quality. A study shows that environmental tracers, which enter rivers via the cooling water from nuclear power stations, can be used to determine this residence time.
