The Bad Bertrich "Bergquelle" is an healing spring. The mineral water rises to the earth's surface from a volcanic fracture at a depth of over 2,300 metres.
The total mineralisation and the natural outlet temperature make the Bad Bertrich healing water the "only Glauber salt thermal spring in Germany, 32°C naturally warm". The healing spring was recognised by the Romans around 2,000 years ago and was expertly secured and preserved.

Its healing properties have made it a recognised healing water. Drinking and bathing cures under supervision are offered in Bad Bertrich with great success. The total mineralisation is approx. 2,479 mg/l. It is a sodium hydrogen carbonate sulphate thermal spring, also called Glauber's salt thermal spring.

The 32° C naturally warm healing water can be taken from the drinking fountain in the Kursaal building and at the Löwenkopfbrunnen fountain in the spa garden. It is recommended in limited quantities before meals. The two drinking fountains are open daily.

Further information and exact withdrawal times can be found on site and in the flyer "Kleine Quellenkunde" as well as in the brochure: "Dreese - Mineralwasser- und Kohlensäurequellen der Vulkaneifel".
