- The study of the physical and chemical parameters of groundwater is one of many elements enabling complete recognition of engineering geology conditions that are used in the designing process of building construction. The degree of groundwater aggressiveness is determined, based on the groundwater components likely to cause foundation corrosion (pH, SO42-2+, NH4+, aggressive CO2) and carried out in accordance with the Polish standard PN-EN 206+A2:2021-08. A series of spatial and statistical analyses of archival data from 40 selected engineering geology documentations from the years 2010-2013 were performed to investigate the potential variability in the degree of aggressiveness of shallow groundwater in Wrocław city. Groundwater from 50 individual research points was analysed. Groundwater components: of pH and contents of aggressive carbon dioxide and sulfate ions have a significant influence on the degree of groundwater aggressiveness. Magnesium and ammonium ions are statistically unimportant. Groundwater aggressiveness environments are spatially variable and are demonstrated not only in the study area, but also within a single investment. More than one analysis is necessary to be performed to evaluate groundwater aggressiveness. This conclusion is also confirmed by the current study conducted in 2021.
