Green roofs and living walls are effective tools for addressing water management challenges in urban environments. These green infrastructure elements can mitigate rainwater runoff, reduce water contamination, and support more sustainable flow regulation. They also contribute to temperature regulation and provide habitat support for urban wildlife. Careful plant selection can maximize the positive impact of green infrastructure, reducing pollution levels and improving water quality in densely populated urban areas with extreme weather conditions. The research presented in this article raises awareness about potential challenges and risks associated with green infrastructure, such as pollutant release. Understanding the factors that influence water quality enables improved management practices and sustainable urban planning. The article also identifies various plant species with remarkable contaminant retention capabilities, particularly several metals such as calcium and sodium. These findings propose the design of effective green infrastructure solutions. This study confirms that green infrastructure effectively filters pollutants from precipitation water, making it suitable for injection into underground water wells. Overall, the research provides valuable scientific insights for urban water management, fostering eco-friendly and resilient cities in semi-arid climates.

In order to better constrain the hydrogeological conditions to the depth of 50 m in the area of water extraction for Wroclaw city, a multi-faceted geophysical survey has been applied. We have combined electrical resistivity tomography (ERT), ground penetrating radar (GPR) and magnetic resonance sounding (MRS) techniques. The results of geophysical investigations indicate the presence of three rock layers with different permeability. The first layer, up to 2 m below ground surface, represents a discontinuous horizon composed of impermeable rocks. The next one, a porous and permeable stratum (aquifer) with a thickness of approx. 5-10 m, comprises saturated sands and gravels. The observed aquifer is characterized by good hydrogeological parameters, wherein hydraulic conductivity (k) equals 5 X 10-4 m/s and porosity reaches 23%. The third layer, below 10 m, is composed of loamy impermeable sediments intercalated with moraine till. At greater depths (>20 m) they are still loamy rocks, but occurring with interbeds of sands (sandy loam). This is confirmed by the hydraulic conductivity in the order of 10-6 m/s, which is typicalfor semi-permeable rocks. Noteworthy, no additional aquifers have been observed to the depth of 50 m.
