摘要
Overexploitation of the aquifers of the Middle Vinalopo (SE Spain) has led to problems which, in many cases, are associated with groundwater salinization. The increase in salinity is considered to be due to the dissolution of mineral salts in the Triassic Keuper facies. Geophysical logging of various bore-holes in three aquifers in this region confirms the presence of more mineralized waters at depth. The evidence suggests that the phenomenon of salinization results from mixing of these deep waters with more shallow ones. The fall in the ratio of freshwater to saltwater as overexploitation continues and the aquifer is emptied could explain the increased mineralization that has been observed at many boreholes that penetrate these aquifers.
