Although still accompanied by winter temperatures, very first nuances of spring made our hearts smile during groundwater sampling at the beautiful Aurich/East-Frisia close to the border of our friendly dutch neighbors.

Two of the sampling wells were particulary interesting, since the freshly sampled, almost transparent water turned completely dark within a minute. A potential reason might be the comparably high levels of Manganese (Mn) in the groundwater, which quickly oxidized to a permanganate once it came in contact with the oxygen of the air. Permanganates express a deep purple color.
