Abstract

Carbonated water and different types of mineral waters are found in south-east Belgium.

Carbonated waters, located mainly in the areas of Spa and Chevron, are old, deep waters the mineralisation of which is largely a function of the lithology of the rocks they pass through. The gas, mainly CO₂ appears to come from deep sedimentary limestone rocks.

The mineral waters in the Spa region have low mineralisation. The phenomenon is related to post-primary prehistoric changes.

The waters at Chaudfontaine are characteristic of limestone formations but have temperatures higher than normal.
