Stormwater ponds improve water quality by facilitating the sedimentation of particles and particulate contaminants from urban runoff. Over time, this function entails accumulation contaminated sediments, which must be removed periodically to maintain a pond's hydraulic treatment capacity. In study, sediments 17 stormwater facilities four Swedish municipalities were analyzed for 259 organic substances likely found in environment. A total 92 detected at least one sample, while as many 52...
Although runoff from trafficked urban areas is recognized as a potentially significant pathway of micropollutants, pollution remains poorly documented, except for relatively few historical pollutants such some metals and hydrocarbons. Therefore, in this work, road parking lot four sites with contrasting traffic levels were analyzed very broad spectrum molecules elements. A total 128 micropollutants monitored, including inorganic (n = 41) organic 87) pollutants. Both the dissolved particulate...
Biochar is often promoted as an ideal amendment for stormwater biofilters; however, its effectiveness has rarely been tested under field conditions. This study evaluates the impact of biochar addition on removal organic micropollutants (OMPs) in field-scale biofilters operating real-world conditions first time. The research comprised four vegetated biofilter facilities (3 - 5 years old), two without and with 2.1 wt. % (10 vol. %) amendment. Stormwater filter material samples from various...
Stormwater runoff is a key pathway for diffuse pollutants to enter receiving waters. Mitigating measures include pollutant substitution, restricting their release into the urban technosphere and limiting (re-)mobilisation of substances minimise negative impacts on Gully pots (GPs) are one most ubiquitous drainage infrastructure components, providing both function onward transport through in-pot sedimentation processes. In this study, sediments accumulated over one-year period were collected...
This field study assessed the occurrence, event mean concentrations (EMCs), and removal of selected organic micro-pollutants (OMPs), namely, polycyclic aromatic hydrocarbons (PAHs), petroleum (PHCs), nonylphenol (NP), 4-t-octylphenol (OP), bisphenol A (BPA), in a gross pollutant trap (GPT)-biofilter/sand filter stormwater treatment train Sundsvall, Sweden. The effects design features each unit, including pre-sedimentation (GPT), sand medium, vegetation, chalk amendment, were investigated by...
Reduction of runoff flow peaks and volumes is one the performance objectives grass swales in context Green Stormwater Infrastructure (GSI). Towards this end, a study feasibility using retrofitted swale outlet control weir (SOCW) to reduce volume peak flow, by enhancing storage infiltration into soils, was conducted Luleå, Northern Sweden. Experimental field work consisted 43 irrigation-driven experiments, mimicking rainfall events with return periods between 1- 50-years, constant intensity...
In the context of increasing urbanization and global warming, there is a growing interest in implementation green infrastructure (GI) across different climates regions. Identifying an appropriate GI design criteria essential to ensure that tailored satisfy local environmental requirements. This article aims compare hydrological performance facilities eleven Swedish cities by isolating effect climatic conditions using identical configuration. Long-term simulations based on 23-years...
This study details the occurrence and concentrations of organic micropollutants (OMPs) in stormwater collected from a highway bridge catchment Sweden. The prioritized OMPs were bisphenol-A (BPA), eight alkylphenols, sixteen polycyclic aromatic hydrocarbons (PAHs), four fractions petroleum (PHCs), along with other global parameters, namely, total carbon (TOC), suspended solids (TSS), turbidity, conductivity (EC). A Monte Carlo (MC) simulation was applied to estimate event mean (EMC) based on...
In order to determine the relative importance of a vegetative filter strip and biofiltration swale in treatment train for road runoff, US EPA Storm Water Management Model was used model infiltration runoff from strip. The consisted series subcatchments representing road, side-slopes swale. Simulations were carried out different rain scenarios variety climatic conditions. addition, sensitivity analysis conducted model's parameters (soil characteristics initial humidity, roughness, geometry,...
Urban stormwater typically enters sewer networks through gully pots, which allow a primary sedimentation of solids upstream the piped network. The regular removal and disposal retained sediment are necessary, costly can involve environmental risks due to contamination sediments with substances from urban environment such as metals. concentrations speciation Cd, Cr, Cu, Ni, Pb Zn were analysed in 26 pots located different land use areas Stockholm, Sweden. In addition, accumulation rates both...
Abstract Stormwater ponds are widely used for controlling runoff quality through the sedimentation of particles and associated pollutants. Their maintenance requires regular removal disposal accumulated material. This necessitates an assessment material hazardousness, including potential hazard due to its contamination by metals. Here we analyze 32 stormwater pond sediment samples from 17 facilities using several chemical analysis methods (total extraction, sequential diffusive gradients in...
La mise en œuvre d'une gestion décentralisée des eaux pluviales implique généralement le recours à systèmes d'infiltration, dont fonctionnement n'est pas toujours correctement appréhendé. Une mauvaise évaluation de l'hydrologie peut s'avérer préjudiciable pour la quantitative et qualitative du ruissellement, notamment dans dispositifs conçus une maîtrise " source flux polluants. Face aux difficultés associées mesure directe d'eau polluants sur ouvrages place, on discute les apports deux...
A stochastic method for evaluating the in situ mass balance of micropollutants a stormwater biofilter, accounting inlet and outlet loads evolution pollutant filter media (ΔMsoil) at an annual scale, is proposed. In field context, this type calculation presents number methodological challenges, associated with estimating water quality unsampled rain events, reconstituting missing or invalidated flow data significant uncertainties these estimations experimental measurements.
