💧 Crowd Research: Reveal Nitrate in Water!

About three-quarters of our drinking water in Germany comes from groundwater. However, in many places, this is contaminated with high nitrate levels. Streams, rivers, lakes, and ditches are also affected. One of the main causes: Over-fertilization due to intensive agriculture and livestock farming. With our nitrate map, we make the invisible contamination visible. It connects official measurement data with current water tests from Greenpeace volunteers and engaged citizens and shows the nitrate pollution of local waters. 🔎 Become a water guardian in your neighborhood! Test the water in your area and help make the nitrate contamination visible. 🌱 Greenpeace Karlsruhe supports you in this!
