Schwefelquelle Östringen

In the Krummbachwald near Östringen there is the enclosed, publicly accessible sulfur spring Östringen, whose water is said to have healing powers and support the immune system. As with the medicinal springs in Bad Mingolsheim and Bad Schönborn, the spring is made up of dissolved, sulfur-containing sodium hydrogen carbonate from the rock . The water comes from the bituminous slate of the Langenbrücken depression. This is the deepest part of the Kraichgaumulde landscape between Ubstadt and Malsch, which extends in an easterly direction to Östringen. When the rock containing pyrites is weathered, the oxidation of the pyrite with subsequent bacterial reduction of the sulfate ion produces hydrogen sulfide . It gives the mineral water the smell of rotten eggs. In contrast to the healing springs in Bad Schönborn and Bad Mingolsheim, which are pumped from a depth of over 40 °C from a depth of 600 m, the water of the Östringen sulfur spring is cold. It contains 1.5 g / l dissolved substances and 30 mg / l hydrogen sulfide. Visitors who regularly drink from it should note that the daily intake of hydrogen sulfide does not exceed the limit of 100 mg.
