Potential Corrosiveness of Mineral Water in the Piwnicza-Zdrój Region

Abstract

Corrosion in water distribution systems has a negative impact not only on the operational infrastructure, but also on the quality of the distributed water. Corrosion reduces the economic profitability of operation due to the damage that occurs, requires repair and limits the efficiency of water distribution. Knowledge of the corrosiveness properties of water is a guide to the proper design and subsequent use of the operational infrastructure for water intakes. It allows for the prediction of potential problems with the possibility of corrosion and suggests ways to prevent it by using materials with increased resistance to corrosive aggressiveness, or considering the use of other methods of reducing the corrosive properties of water. Specific geological and hydrogeological conditions in the Piwniczna region cause the occurrence of therapeutic waters of the carbonate type. The assessment of the corrosive aggressiveness of these waters is an important factor influencing the operational infrastructure. To determine the corrosive aggressiveness of waters, the values of selected indexes were determined: Ryznar, Langelier and Larson-Skold. The calculated corrosive aggressiveness indexes for waters from the Piwniczna-Zdrój region are varied. Water from P-14 well shows potentially highly corrosive properties, waters taken from P-7 and P-8 wells are non-corrosive. Therapeutic waters from other wells from the Piwniczna region (P-1, P-2, P-5, P-6, P-9, P-11, P-16, P-17 and P-18) can be characterized as temporarily aggressive waters or with low corrosive properties.
