XXIV Congresso Brasileiro de Águas Subterrâneas

GROUNDWATER: THE FOUNDATION FOR ADDRESSING CLIMATE CHANGE AND ADVANCING SUSTAINABILITY IN AGRICULTURE, MINING, AND SANITATION. Groundwater remains Brazil’s most strategic water resource, essential for public supply, agricultural production, industrial and mining activities, and the maintenance of ecosystems. In a country marked by unequal access to water and increasing vulnerability to climate change, its relevance continues to grow.
Today, more than 624 m³/s of drinking water are extracted from aquifers through 2.8 million wells, supplying partially or entirely 52% of Brazilian municipalities and generating over R$100 billion annually for the economy. Groundwater sustains rivers, wetlands, mangroves, and life itself across multiple biomes—an invisible yet indispensable natural infrastructure.
By 2026, the challenges become even more complex:
The increasingly severe impacts of global warming;
The rapid advancement of artificial intelligence, sensors, advanced geophysics, big data, and integrative modeling;
Agribusiness demand for water security;
The need for responsible mining aligned with ESG practices;
The urgency of expanding basic sanitation and the use of wells for water supply.
In this context, CABAS 2026 proposes unprecedented connections among science, technology, innovation, public policy, and the main water-using sectors—building real bridges between academia, industry, drilling professionals, companies, managers, and society.
The Congress will gather the leading professionals in water resources, alongside a renewed and expanded FENÁGUA and an even stronger Well Drillers Meeting, consolidating CABAS as the largest groundwater event in Latin America.
You will be most welcome in São Paulo—the Brazilian capital of groundwater in 2026.

IAH 2026 – The 53rd World Groundwater Congress

Groundwater – A Key Multi-Resource. We are delighted to invite you to the 53rd World Groundwater Congress of the International Association of Hydrogeologists, taking place from 14 to 18 September 2026. This prestigious event returns to Hungary after half a century, and we are proud to welcome you again to the beautiful city of Budapest. This city is connected to water in many ways. The Danube River flows majestically through the heart of Budapest, providing drinking water for 1.8 million people through the efficient riverbank filtration technology. Budapest is also known as the city of spas, because there is no other place in the world with so many natural hot springs and spas offering relaxing and therapeutic experiences. The naturally discharging thermal waters have shaped the city's karst landscape, creating unique hypogenic caves and mineral formations. Due to the favorable natural conditions, geothermal energy exploration gains importance in the area in response to the growing global demand for sustainable energy solutions. The topics of the conference highlight the diverse and critical roles that groundwater plays in environmental sustainability, resource management, and societal well-being. Thus, we aim to provide a platform for leading experts, researchers, and professionals from around the globe to engage in discussions and explore the multifaceted role of groundwater in our world.

Join us in Budapest for an unforgettable experience! We will foster a collaborative environment in which we can all learn and drive forward the field of groundwater resources.
