Natural curative resources

Natural resources of Ciechocinek are the abounding deposits of thermal brines, which thanks to the presence of sodium chloride, calcium compounds, magnesium compounds, iron compounds, free sulphuretted hydrogen, iodine, bromine and other trace elements, have extraordinary curative qualities. Their temperature is from 8 to 370°C, and their salinity – from 0,19% to 6,43%. Since 1841, as the first intake of brine has been bored 19 further exploitation intakes have been carried out.

At present following brine bore-holes are being utilized:

Bore hole 11 (Grzybek)
4,51% chloride–soda water (brine), bromide water, iodide water, boronide water, fluoride water

Bore hole no 17
0,79% chloride–soda water, bromide water, bromide water, boronide water

Bore hole no 17a
0,19% chloride–carbohydrate–soda-calcium water

Bore hole no 17b
0,22% chloride-soda water, bromide water

Bore hole no 19
0,33% chloride-soda water

Bore hole no 19a
0,35% chloride-soda water

Thermal spring XIV
4,43% hypothermal (27°C) bromide water, iodide water, boronide water, sulfide water

Thermal spring XVI
6,43% hypothermal (33°C) bromide-iodide-ferruginous-boronide water

The brine is utilized for healing baths, its influence onto the human organism depends upon the activity of the chemical, thermical and hydrostatic factor. With a suitable concentration, the same mineral water is used for individual or group inhalations as well as for irrigation. Spring no 19 delivers water of 11% concentration, which is bottled as mineral water “Krystynka” and “Kujawianka”.
