“…Because dissolved metals cannot be removed mechanically with solids (e.g., by sedimentation and filtration), a second treatment step (e.g., filter media) is necessary to reduce higher metal runoff concentrations Minervini, 2010;Kayhanian et al, 2012). Maniquiz-Redillas and Kim (2014) investigated the partitioning of heavy metals in runoff and in the effluent of a stormwater treatment plant (manufactured eco-biofilter) and concluded that the fractionation of heavy metals plays an important role on the performance of the system and a reduction of dissolved metal concentrations is necessary. It is recommended that not only the initial runoff or the first 25% of the total runoff should be treated but the entire water volume (Flint and Davis, 2007;Maniquiz-Redillas and Kim, 2014).…”

“…If conditions change, particulate metals transported into receiving waters have the potential to repartition into the dissolved phase (Sansalone, 2002;Westerlund and Viklander, 2006). Metal partitioning is also important for designing appropriate stormwater treatment strategies (Hilliges et al, 2013;Maniquiz-Redillas and Kim, 2014).…”

“…To reduce particulate loadings for the filter materials, pretreatment ahead of the filter is required [19]. Both mechanical and chemical steps are necessary to sufficiently reduce dissolved and total metal concentrations [20,21]. Laboratory studies of the filter materials are necessary to develop new treatment systems, to control and optimize existing ones, and to determine application areas and service lives.…”

For the development of decentralized treatment systems for road runoff, the determination of pollutant removal capacities is essential. The aim of this study was to evaluate the impact of boundary conditions on the simultaneous removal of copper, nickel, and zinc by six sorbents used for urban stormwater treatment (i.e., granular activated alumina, anthracite, granular reactivated carbon, granular ferric hydroxide, calcium carbonate, and granular activated lignite). For batch experiments, capacities were determined at initial concentrations within the range of 2.5-180 mg/L with a rotary shaker. Further influences were investigated: the use of a horizontal shaker for concentrations of up to 1080 mg/L, a variation of the initial pH value (5 and 7), and the presence of a buffer. Furthermore, the influences of the filtration process on the capacities were studied. Kinetic experiments were conducted for contact times between 5 min and 120 min. Lab-scale column experiments with inflow concentrations of 2.5 mg/L (copper and nickel) and 5.0 mg/L (zinc) at an initial pH of 5 and a contact time of 11 min were performed for comparison. Selected experiments were subsequently carried out with changes in initial concentrations and contact time. One result is that it is essential to conduct batch experiments with the metals of interest. The capacities determined by column experiments deviated from batch experiments. Batch experiments under well-defined conditions can be used to evaluate different production batches. Column experiments give a more faithful capacity by considering realistic boundary conditions and should be preferred to determine efficiencies and service lives.

“…Approximately 60 and 80 % of Cu and BaP, respectively, can be expected in the non-dissolved phases of stormwater, although large partition variations exist (Brown 2002, Camponelli et al 2010, Maniquiz-Redillas and Kim 2014, Prestes et al 2006, StormTac corporation 2016, WERF 2016. Generally, the highest loads of both BaP and Cu are found in the fine particle fractions (< 30 µm) (Herngren et al 2010, Nielsen 2015, Sansalone et al 1998, WERF 2016.…”

The risk from chemical substances in surface waters is often increased during wet weather, due to surface runoff, combined sewer overflows (CSOs) and erosion of contaminated land. There are strong incentives to improve the quality of surface waters affected by human activities, not only from ecotoxicity and ecosystem health perspectives, but also for drinking water and recreational purposes. The aim of this study is to investigate the influence of urban stormwater discharges and CSOs on receiving water in the context of chemical health risks and recreational water quality. Transport of copper (Cu) and benzo[a]pyrene (BaP) in the Göta River (Sweden) was simulated using a hydrodynamic model. Within the 16 km modelled section, 35 CSO and 16 urban stormwater point discharges, as well as the effluent from a major wastewater treatment plant, were included. Pollutant concentrations in the river were simulated for two rain events and investigated at 13 suggested bathing sites. The simulations indicate that water quality guideline values for Cu are exceeded at several sites, and that stormwater discharges generally give rise to higher Cu and BaP concentrations than CSOs. Due to the location of point discharges and the river current inhibiting lateral mixing, the north shore of the river is better suited for bathing. Peak concentrations have a short duration; increased concentrations of the pollutants may however be present for several days after a rain event. Monitoring of river water quality indicates that simulated Cu and BaP concentrations are in the same order of magnitude as measured concentrations. It is concluded that hydrodynamic modelling is a useful tool for identifying suitable bathing sites in urban surface waters and areas of concern where mitigation measures should be implemented to improve water quality.
