Concentration, distribution, and fractionation of metals in the filter material of 29 bioretention facilities: a field study
To maintain function in biofilters over time and reduce risk for leakage of metals, regular maintenance, including replacement of top layer is recommended. However, consider metal fractionation when handling material.

About this collection
Guest edited by Luca Vezzaro (Technical University of Denmark, Denmark), Nathalie Gilbert (Thames21, United Kingdom), Lian Lundy (Middlesex University, United Kingdom & Luleå University of Technology, Sweden), María Nariné Torres Cajiao (Xylem Inc., USA), and Kefeng Zhang (UNSW Sydney, Australia) this themed collection provides an overview of the current issues and solutions for the sustainable management of water quality from wet-weather discharges (both from combined and separate storm systems), with a specific focus on multidisciplinary aspects.
The transition of urban areas towards Water-Wise Cities (also known as Sustainable Water Systems) has renewed interest in the management of stormwater. While the main focus of the last decade has been the quantitative management of stormwater (due to the focus on climate change adaptation and flood risk reduction), several issues linked to the management of stormwater quality remain open. Environmental impacts from both Combined Sewer Overflows (CSOs) and separate storm outlets represent a challenge for urban water managers, while increasing demand for water reuse requires more robust information on the quality of the different water fluxes crossing the city.
