The freshwater dilemma
Graciosa Island is located in the northern part of the central group of the Azores. This island is currently experiencing seawater intrusion into the groundwater aquifer, which, if not improved, will pose a significant threat to the island's ecosystem and the health of its inhabitants. There are two reasons for this situation to arise. The first reason is That there are no lakes or rivers on the island, the islanders rely heavily on groundwater for their daily water. Excessive groundwater extraction leads to aquifers can not being recharged in time, which eventually led to seawater intrusion.
