The dataset also includes results from aging experiments performed on silica gels, including syneresis measurements, leachate pH, degradation rates, and the chemical composition of leachate products released during the aging stage. In addition, data obtained from XRD, FTIR, and XRF analyses are provided. Furthermore, the dataset includes PHREEQC input files used for equilibrium and kinetic geochemical modeling, together with the corresponding simulation results. These modeling results were used to evaluate the interaction between silica gel leachate and shallow Dutch groundwater and to assess the potential risk of well clogging caused by precipitation of leachate-derived products.
