International Commission for the Protection of the Danube River and the ground water resources. The ICPDR’ legal basis is the “Convention on Cooperation for the Protection and Sustainable use of the Danube River (Danube River Protection Convention)”, generally referred to as the “Danube River Protection Convention” or “DRPC”. It commits the contracting parties to join their efforts in sustainable water management, including conservation of surface and ground water, pollution reduction, and the prevention and control of floods, accidents and ice hazards. The convention was signed in Sofia, Bulgaria, in 1994 and came into force in October 1998. The ICPDR was created to implement the Danube River Protection Convention (DRPC).
