Abstrakt

The paper presents laboratory experiments on the influence of different hardness water samples collected from the municipal water supply system on the intensification of leaching pollutants from the internal cement mortar pipe lining to drinking water. The paper presents the analysis of water quality indices, such as pH, aluminum and selected heavy metals concentrations after contacting with cement coatings.
