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.

With high demands on quality and accuracy of the analytical results, we have established a quality management system for our chemical testing laboratory according to the guidelines of ÖVE/ÖNORM EN ISO/IEC 17025. In September 2010, the laboratory was accredited as a testing laboratory by the Federal Ministry of Economics, Family and Youth (BMWFJ).
(GZ: BMWFJ-92.714/0659-I/12/2010 Identification No. [PSID] 315) Our analyses are carried out in accordance with national and international standards. All procedures are laid down in our quality management manual, which our customers are welcome to consult. The correctness of our work is confirmed several times a year by international interlaboratory comparisons.
