    Notizen: Abstract  The Alto Guadalentín detrital aquifer is both overexploited and polluted. Water conductivity ranges between 1200 and 4900 μS cm–1, HCO3 – between 1000 and 1990 mg l–1, and PCO2 between 0.041 and 1.497 bars. The temperature and chemical composition of the water show a positive thermal anomaly directly attributable to the neotectonic activity in the area. The high CO2 content has caused the abandonment of numerous wells due to water corrosiveness which attacks pumping equipment.

    Hydrogeochemical effects of groundwater mining of the Sierra de Crevillente Aquifer (Alicante, Spain) (1995)
    Springer
    Environmental geology 26 (1995), S. 232-239

    ISSN: 1432-0495

    Thema: Geologie und Paläontologie
    Notizen: Abstract The groundwater mining of the Crevillente aquifer (southeastern Spain) has resulted in the progressive deterioration of water quality, with particularly significant increases in chloride, sulfate, and sodium. The possibility of a vertical hydrochemical zoning is deduced that would require examining the importance of the geometry and lithology (evaporitic materials) in the salinization process. The time of water-rock contact (residence time) and dilution by infiltration of rainwater also influences the hydrogeochemistry of the aquifer. The hydrochemical data are useful in defining the conceptual model of the aquifer, completely karstified with relative homogeneity.
