Bílina acidulous healing water is collected above the slope foothill area located on the left bank of Bílina River, in the so-called Bílina crystallinicum, enlisted to the Ore Mountain region. Through the Northern part of the territory, a significant system of parallel disturbs in East-West direction runs, referred to as Bílina fault (in the sense of Hibsch 1924, Václ 1982, and/or Prášil 1982), which tectonically marks the boundaries of the crystallinicum & neogenous pelvic sediments liaison.
Bílina mineral water is cold, true and genuine alkaline acidulous spring water. A natural, strongly mineralized sodium hydrocarbonate acidulous water with an increased content of fluorine, hypotonic, with a total content of solid components featuring 7300 mg/l, and a content of free CO2 ranging between 2100 and 2700 mg/litre.
The output of mineral waters is possible due to a favourable geo-tectonic disposition. The sector where mineral waters get created needs to be looked for in shear zones of the ortorule complex. The fault limitation and the crystalline fault black segmentation are conditioned on faults heading the Bílina River in North-north-East to South-south-West, and West-north-West to East-south-East directions, with hidden zones running in an almost West-to-East direction, reaching as far as the Bílina River from the slopes of Ore Mountains. As for the venue of proper occurrence of mineral water springs, Bílina acidulous water probably gets there from the West, following the West-to-East shear zones of the ortorule complex. In terms of the output phase of the acidulous water in the sub-surface part, of key significance is the prevailing direction of open fault clefts of h2, i.e. North-north-East to South-south-West, direction.
Carbonated acid gas is of juvenile origin, the creation zone thereof lies is related to tertiary Bohemian Mid-Mountain Range volcanism. Chemical composition of the mineral water is the result of interaction of subsoil water with aluminicate ortorule systems in the presence of CO2.
Bílina acidulous water is collected from a 190,6-meters deep source – drill well, to be transferred, via underground piping, and stored - at a constant temperature - in water tanks. Therefrom, without any adjustments and/or chemical conservation whatsoever, it is brought to the pressurized bottle filler installed in the premises of the filling hall.
With such considerate process in place, almost the entire original amount of smoothly dispersed carbon dioxide, vital for the luscious taste of the mineral water, is preserved.
