Conclusions

  • Groundwater resources play significant role in Hungary as well as in the whole

Carpathian Bain. Many specialties. Main source of drinking water supply

  • The increasing utilization of mineral, medicinal and thermal water resources is

important national interest. National Development Plan

  • Realization of integrated groundwater management. The importance of

transboundary collaboration concerning surface and groundwater resources

  • Many tasks and challenges for hydrogeologists inside the Carpathian basin. 1/3
  • f groundwater bodies in Hungary are not in good condition
