This paper shares an early-career perspective on potential themes for the upcoming International Association of Hydrological Sciences (IAHS) Scientific Decade (SD). opinion synthesizes six discussion sessions in western Europe identifying three that all offer a different hydrological threats world faces and could serve to direct broader community: “Tipping points thresholds hydrology,” “Intensification water cycle,” “Water services under pressure.” Additionally, four trends were...
Pressure on freshwater resources is increasing due to growing water demand for agricultural, industrial and domestic use. The effects of climate change, such as longer periods drought, further increase demand. In addition pressure quantity, quality affected by pollution, including groundwater resources. Therefore, sustainable resilient approaches use are needed.Managed aquifer recharge (MAR) can secure supplies expanding the amount storage available. At same time, MAR improve through...
Abstract. Biocides used in film protection products leaching from facades are known to be a potential threat the environment. This study identifies individual sources and entry pathways small-scale urban area. We investigate emissions of commonly biocides (terbutryn, diuron, octylisothiazolinone – OIT) some their transformation (TPs; diuron-desmethyl, terbumeton, terbuthylazine-2-hydroxy, terbutryn-desethyl) 2 ha residential area 13 years after construction has ended. Sampling utilizes...
Abstract Urban stormwater contains various micropollutants, such as biocides, which are washed off from facades during wind-driven rain events. Biocides can reach the groundwater via infiltration systems (SIS), although soil layer acts a reactive barrier preventing leaching of biocides but producing transformation products (TPs). Little is known about occurrence and concentration in SIS soils, their distribution temporal behavior. Here, we present first systematic screening three commonly...

Abstract Biocides used in paints and renders prevent algae fungi growth but can wash off during wind-driven rain enter urban environments. Retention ponds represent part of stormwater management that retain water partly pollutants. However, it is poorly understood which percentage biocides leached from facades reaches a pond how efficiently are retained inside although have harmful environmental effects. Here, we combined measurements modeling to address diffuse biocide loss pond's retention...
Biocides leached from facades can reach urban groundwater, where they have adverse environmental impacts. They are used in film preservatives and enter groundwater via swale-trench systems or diffuse pathways. However, there is little information on occurring biocide loads along different pathways to groundwater. The aim of this study quantify the input, transport degradation biocides pathways, namely infiltration (1) systems, (2) adjacent vegetated soils, (3) through permeable pavements....

Biocides used as film protection in paints and renders wash off from facades enter the urban water cycle. They can also reach groundwater, diffusely or at specific locations via stormwater infiltration systems (SIS). Up to now, there is limited knowledge estimate biocide input groundwater larger scales. This study focuses on an area of 38ha models including SIS. The aim determine preferential locations, SIS retention capacities, transport degradation biocides saturated zone. located...
<p>Biocides added to facade renders and paints prevent algae fungi growing at conventional buildings. During rain events biocides leach from facades into the urban environment its compartments i.e. soil, surface water groundwater. In many cases polluted façade runoff reaches partly sealed pavements a major part infiltrates. Transport transformation processes of below these are largely unknown. It may be hypothesized that concentrated infiltration in joints...
<p>Urban swales collect stormwater runoff containing micropollutants such as biocides washed off from facades during wind driven rain. Although retain contaminants, they might eventually reach groundwater through soil. However, there is little data available of biocide occurrence in urban swale sediment. In this study, we measured the entry to an and its distribution The selected south-west Germany collects a 3 ha residential area with 46 houses. Two pipes lead into swale, one...
<p>Biocides used as film protection products to prevent algae and fungi growth on facades wash off during rain events represent a potential risk the environment. So far, urban monitoring studies focused mainly large heterogeneous areas. Thus, little information about individual sources entry pathways were obtained. However, this is important understand of biocide groundwater.</p><p>This study investigates emissions from 2 ha residential area, 13...
