The brine from Zabłocie is subject to regular analyses since 1894.

The results of analyses indicate chemical stability of its composition since over one hundred years.

Slight variations in the content of individual ions and mineralization are something natural or may be associated with various test methods used by individual laboratories.

To trace the chemical composition of the brine since the first test in 1894 performed by E. Ludwig until the present time, the Table 5 below summarizes the analyses for a temporal interval of 117 years.



A - analysis made by E. Ludwig,

B - analysis made by the Department of Scientific Research in Szczawno Zdrój, included in Papierkowski (1959) and Dowgiałło et al. (1969),

C - analysis made by the BP "Balneoprojekt" laboratory in Szczawno Zdrój, included in hydrogeological documentation (1976)

D - the analysis made by the BP "Balneoprojekt" laboratory in Szczawno Zdrój

E - analysis made by the laboratory of the Central Mining Institute.

The brine is covered by the declaration in the National System of Information of Cosmetics Placed on the Market, kept by the Institute of Occupational Medicine named after professor J. Nofer in Lódź at no. RK/254759/2009 dated 17. 09. 2009, as a cosmetic product used in the form of an addition to body bath, having the following useful properties: "removes fatigue, refreshes, helps achieve smooth, firm and elastic skin.

The company has the right to exploit the brine through the Korona drillhole within the mining area, which has the form of a square with the side of the 1000 m and covers the area from the border of land to the bottom of the Miocene layer within the Skawina and Dębowiec formation. The reserves of medicinal water have been documented in "Appendix No. 1 to the geological documentation establishing the medicinal groundwater resources from "Tadeusz" and "Korona" drillholes in Zabłocie on updating the exploitable resources of medicinal waters obtained from "Korona" drillhole, adopted by the letter sign. DGiKGkdh 4791 31-2/6722/1681/09/M dated 10. 04. 2009, constituting the update to the "Geological documentation establishing the medicinal groundwater resources in Zabłocie" of 1976". Contractor: Office of Design and Technical Services for Balneotherapy Industry "Balneoprojekt" Warsaw, ul. Rolna 179/181 and approved by the President of CUG dated 09. 12. 1977, sign. KDH/013/4244/B/77.

"Korona" drillhole drilled in 1892 and used extensively to mid-80s of the twentieth century, is located in Zabłocie, at Bielska street within dispersed rural housing area provided for use in the exploitation of brine using the drillhole. For the project, an analysis of environmental conditions was performed and no need to conduct an environmental impact assessment of this project was found. The project site is located in the western part of the Carpathian foredeep in the south, not fitted out by the coal mining part of the Upper Silesian Coal Basin. The project is located in the area of ​​special protection of bird habitat Natura 2000 PLB240001 Upper Vistula Valley, on the north-western edge of the area.

State Institute of Hygiene

National Institute of Public Health - State Institute of Hygiene issued "The determination of underground water from the "Korona" drillhole in Zabłocie, in terms of its use for medicinal purposes or production of preventive health products" No. HU/51/2010 dated 19. 05. 2011. It states that the brine in its natural state after filtration of the precipitated components can be used for medicinal baths or after suitable dilution (according to medical indications) for inhalation or bath for the purpose of rehabilitation. In addition, after appropriate dilution with spring water or natural mineral water with low mineral content, the brine can be used to manufacture a supplement for the deficiency of iodine in the human body.

Publications and certificates

Brine from the "Korona" drillhole in Zabłocie is used as a raw material for cosmetics and balneological products.The deposit of brine is located in the village of Zabłocie, in Strumień municipality. It has been mined since it was made available through the "Korona" drillhole in 1892. The brine has been used since the turn of the century for medicinal purposes (baths and inhalations), initially under the name "Zablaczer Kronenjodwasser. "

The mining plant gives access to water relics from warm Miocene sea, surging at great depths: 300 - 650 m ppt., which are a kind of preserved algae extract and currently, a deposit of medicinal iodide, sodium chloride water, rich in minerals necessary for health - iodine, calcium, magnesium and iron, as well as valuable trace elements: silicon, strontium and boron. This is typical of groundwater located in deep geological levels isolated from the surface. Water has a therapeutic iodine content - on average, 135 mg/l, up to a known 139 mg/l and contains iron - approx. 10 mg/l.
