Warding off freshwater salinization: Do current criteria measure up?

Salinization is a global threat to freshwater habitats that has been intensified by climate change. In our work in Austrian waters, we repeatedly encounter algae and animals that actually belong in brackish or saline water and not in freshwater. But how is salinity actually assessed?

A contribution to the topic of salinity criteria for the protection of freshwater ecosystems. (Download)

World Water Day 2022

This year, the World Water Day proclaimed by the United Nations has the motto “Groundwater – making the invisible visible”

World Water Day 2022
Wasseraktiv – BMLRT

° Groundwater is invisible, but its impact is visible everywhere.

° Almost all of the liquid freshwater in the world is groundwater, supporting drinking water supplies, sanitation systems, farming, industry and ecosystems.

° What we do on the surface matters underground. We must only put harmless, biodegradable products on the soil and use water as efficiently as possible.

° Groundwater crosses borders. We must work together to manage transboundary groundwater resources.

° We cannot manage what we do not measure. Groundwater must be thoroughly explored, analyzed and monitored.

° Groundwater will play a critical role in adapting to climate change. We must protect and explore groundwater, balancing the needs of people and the planet.


Peace for Ukraine

We took these peaceful pictures in and around Donetsk in 2014. Since then, we were determined to make a contribution to improving the ecological state of waters in this Danube riparian state during several projects. Now, we are committed to the people in this country who are experiencing unbelievable suffering. We will shift our shock and dismay into action. In addition to the private effort of our employees to help, we will also do our utmost as a company to support and to express our solidarity.


Start of the flowing water sampling season 2022
