[2] It is said that in 1903 on the Namedy peninsula, a 343 m deep borehole was drilled into a CO2-containing aquifer to extract carbon dioxide for mineral water.

The reason for boring the hole at this location was that CO2 gas bubbles were seen rising in the waters of the old Rhine oxbow lake.

[3] In the late 1990s, efforts were made to enable the geyser to become a tourist attraction again, but these conflicted with strict conservation obligations to which the area had been subject since 1985.

The Federation for the Environment and Conservation (BUND) presented a case to the Higher Administrative Court of Rhineland-Palatinate to prevent the further development of the geyser for tourism within the nature reserve.

[4] In May 2005, the town of Andernach and the BUND settled out of court to allow the geyser to be reactivated under certain conservation conditions and for tourism purposes.
