The Guarani Aquifer System (GAS) is a transboundary aquifer that encompasses Argentina, Brazil, Paraguay and Uruguay (Figure 1). It covers an area of 1,100,000 km2 within the Paraná Sedimentary Basin. In August 2010, the four states signed the Agreement on the Guarani Aquifer, which is the first shared-management agreement for a transboundary aquifer in Latin America.
