PROSPECTS OF USING BROWN WATER FROM THE MIOCENE AQUIFER OF THE WIELKOPOLSKA REGION FOR PHYSIOTHERAPYAbstract. The Miocene aquifer formations of the Wielkopolska region are marked by the zonal occurrence of "brown water" with the colour intensity ranging from several hundred to several thousand mg Pt/l. Its origin is linked to the presence of organic matter dispersed in the sand formations, and the zonal character of its occurrence results from the paleohydrogeological conditions of water circulation and exchange. Brown water is not suitable for drinking purposes, and its co-occurrence with the water of low colour intensity impedes the exploitation of usable water. However, in view of the conducted pharmacodynamic analysis, such water shows high biological activity and has beneficial influence on living organisms. Therefore, it can be applied in balneotherapy. The article presents basic information on the occurrence and origin of brown water in the Wielkopolska region, as well as the results of preliminary chemical analyses of brown water collected from five selected wells. The study revealed that brown water containing humus substances amounting to over 200 mg/l and showing high colour durability following its collection from the water-bearing layer is especially useful for the purposes of therapy. Such water was found in two out of the five studied wells, and if can be used for baleotherapeutical purposes.
