“…The diffusion coefficient in the sphere D e for SO 4 2− is set to 1.43·10 −10 · m 2 · s −1 . This value was determined by Hill (1984) in chalk samples, which feature a comparable total porosity (0.45) as the coarse-grained bricks act as stagnant zones (0.42; Wessolek et al, 2011). This yields an exchange factor α of 1.13·10 −7 · s −1 .…”

High sulfate concentrations in the groundwater occur in several cities and particularly in Berlin, Germany. Building rubble-composed soils and landfills are a major source of dissolved sulfates. This study assesses the sulfate release dynamics of such rubble-composed substrates. The substrate was taken from a building rubble landfill in Berlin, which was created after World War II. It was poured into two lysimeters, which were irrigated repeatedly for 2 years to simulate several years of groundwater recharge. Sulfate concentration in the leachate was measured monthly. Sulfate release dynamics were effectively described with PHREEQC, assuming either one or two sulfate pools with kinetically limited dissolution. The volume that percolated the lysimeter column was 2,440 L, corresponding to 17 years of local groundwater recharge. At the beginning, sulfate concentrations increased from approximately 10·10 −3 mol ·L −1 to 13·10 −3 mol · L −1 , which is close to gypsum solubility concentration. After 1.8 pore volumes, a decrease was observed, and after 8 pore volumes, concentrations were relatively constant at levels less than 3·10 −3 mol · L −1 . The data were best described by a model that included a kinetically limited dissolution of gypsum from two sulfate pools different in their effective surface areas. One pool can be ascribed to fine-grained gypsum particles, whereas the other can be ascribed to coarse-grained ones. Overall, rubble-composed substrates can be a severe long-term source of sulfates.

“…In the figure, a typical rubble soil profile is displayed along with Kosela's artwork from 2002. More information on Devil's Mountain, long-term sulfate leaching, and artistic approaches are given by Abel et al (2015), Wessolek et al (2011), and 2014. The problem of addressing soil memory and cultural heritage of war-affected soils in the context of cultural ecosystem services is dealt with in Wessolek and Toland (2017).…”

The rise of industrialized agriculture, coupled with a global demographic shift toward urbanization, has marginalized every‐day connections between individuals and soils. This societal shift has led to a decline in the appreciation of and cultural identity with soils. Amid a broader movement aimed at fostering soil awareness and environmental action, many artists and designers have been instrumental in bringing soils to the cultural mainstream, figuring their esthetic, social, political, and ecological dimensions. Contemporary artists place great importance on the underlying idea of animating soils through artistic practice, often transcending the physical artifact itself to assign agency to soils and the myriad beings that occupy them. Artists harness a multitude of media to articulate human‐soil relationships. From the early environmental art movements of the 1960s and 1970s to contemporary works centered on urban and industrial brownfields, soils’ multifaceted roles in CO2 transformation, water and nutrient cycling, agriculture, and as living bodies buffering against pollution have become ground for public discourse. What could this mean for the vadose zone in terms of reflecting on material flows in porous media beyond understandings of soil physics? In this paper, we draw on over 20 years of experience in studying the portrayal of soil in various arts genres to deliberate the potential of creative thinking about and thinking with the vadose zone.

“…With modern machines, sediment, and pollutant particles down to the size of PM10 are cleaned from street surfaces (Chang et al, 2004). A special form of cleaning is the application of pesticides for weed control on mosaic pavements (Wessolek et al, 2011). Weed control of pavements is considered necessary in many cities as pavements covered with moss can easily get slippery which may affect pedestrian safety.…”

Urban diffuse pollution affects water resources as much as its rural counterpart does; however, it is considerably less studied. The full complexity of the urban landscape needs to be addressed to apprehend the diversity of surface layouts and covers, multiple pollution sources, and the diverse changes caused by different types of drainage systems. In this article, crucial patterns of pollution source areas are categorized, and current knowledge on their temporal and spatial variations are collated. Urban alterations of transport processes that enhance, delay, or inhibit diffuse pollution transport from source areas through the urban watershed are detailed. Current knowledge regarding diffuse pollution patterns and processes is conceptually merged by the simultaneous assessment of urban structural and functional connectivity relevant for pollutant transfer. Applying a more holistic approach is considered a prerequisite for identifying critical source areas of diffuse pollution within complex urban catchments, to minimize the transfer of particular harmful pollutants and to enhance future management of urban waters.
