The evolution of unique geological ratios in the area of the Mariánské Lázně springs caused a high degree of distinctness in the groundwater streams. This resulted in their high individuality and notable chemical and hydrological differences.
The groundwater streams can be divided into two basic groups:
- Main groundwater streams flowing from higher levels. They contain a lot of CO2 and salt. The main stream splits into many little streams when close to the surface and the water changes its chemical composition.
- Side groundwater streams split into many single streams at high levels and mix with mineralized water under the surface where ions of calcium, iron and magnesium percolate.
The above-mentioned distinctions may to a certain extent be applied to springs classified according to their chemical composition.
There are 5 types of springs in Mariánské Lázně:
- Hydrocarbonate-calcium-sulphate-ferrous acidulous waters (Cross Spring, Ferdinand's Spring)
- Hypotonic hydrocarbonate-calcium-sulphate-ferrous acidulous waters (Forest Spring)
- Ferrous acidulous waters with bivalent ferrum and a high content of vanadium (Ambrose's Springs)
- Highly ferrous acidulous waters (Rudolph's and Prelate's Spring)
- Acidulous waters (Mary's Springs, Hamelika)
