Bioretention systems are designed for quality treatment of stormwater. Particulate contaminants commonly treated efficiently and accumulate mainly in the surface layer bioretention filter material. However, concerns exist that microplastic particles may not show equal accumulation behavior as other sediment particles. So far only two field laboratory studies available on fate microplastics few relatively newly built systems. Therefore, this study investigated abundance distribution nine 7-12...
Permeable pavements benefit urban hydrology through detention of stormwater in the aggregate base and subsequent exfiltration to underlying soil. The majority previous research has focused on permeable constructed sandy soils and/or treating only direct rainfall. Four employing internal water storage (IWS) zones situated over low-permeability were intensively monitored for their hydrologic performance northern Ohio. Volume reduction varied from 16 53% with low drawdown rates (<0.35 mm/h)...
Abstract Stormwater runoff from urban development causes undesired impacts to surface waters, including discharge of pollutants, erosion, and loss habitat. A treatment train consisting permeable interlocking concrete pavement underground stormwater harvesting was monitored quantify water quality improvements. The provided primary the cistern contributed final polishing total suspended solids (TSS) turbidity concentrations (&gt;96%) loads (99.5% for TSS). Because this, &gt;40%...
Abstract Permeable pavements are implemented to provide at‐source treatment of urban stormwater runoff while supporting vehicular and pedestrian use. Studies on these systems have mainly focused those treating only direct rainfall installed atop well‐drained soils which typically substantial hydrologic mitigation through exfiltration that may not be representative more hydrologically taxing conditions. A single lane parking area retrofitted with permeable interlocking concrete pavement in...
Current knowledge about the fate and transport behaviors of per- polyfluoroalkyl substances (PFASs) in urban stormwater biofilter facilities is very limited. C5–14,16 perfluoroalkyl carboxylic acids [perfluorinated (PFCAs)], C4,8,10 perfluoroalkanesulfonic (PFSAs), methyl-perfluorooctane sulfonamide acetic acid (MeFOSAA, a PFSA precursor), unknown C6–8 PFCA perfluorooctanesulfonic precursors were frequently found bioretention media forebay sediments at Σ35PFAS concentrations <0.03–19...
A comparison was made of the Guelph permeameter, velocity a pumping test procedure, and auger hole method for measuring saturated hydraulic conductivity. The methods were compared on Ravenna silt loam Hoytville silty clay loam. evaluations conducted during high water table conditions established by subirrigation. All showed wide variability in conductivity within each research plot. test, hole, permeameter provided results similar ranges whereas significantly lower estimates. Saturated...
To maintain function in biofilters over time and reduce risk for leakage of metals, regular maintenance, including replacement top layer is recommended. However, consider metal fractionation when handling material.
Stormwater runoff from urban development causes undesired impacts to surface waters, including discharge of pollutants, stream erosion, and loss in-stream habitat. control measures (SCMs), such as ponds, wetlands, bioretention cells, permeable pavements, are employed ameliorate these impacts. A treatment train SCM was constructed monitored in the parking lot at Old Woman Creek National Estuarine Research Reserve Huron, Ohio. Native soils beneath this were heavy clay with measured average...
The hydrologic performance of permeable pavement varies widely due to underlying soil type, drainage configuration, contributing area, surface infiltration rate, and aggregate depth. A long-term model is needed better understand the influence these design variables on runoff, drainage, exfiltration, evaporation from systems. Most models have not been calibrated with field monitored data, are usually unable accurately internal water storage (IWS) zones, do account for profile. Because employs...
While bioretention cells have been shown to ameliorate nutrient pollution in urban stormwater, previous studies show newly installed soil media (BSM) may leach nutrients. This leaching has attributed use of compost BSM. Compost is often recommended as a component BSM maintain plant health. Stormwater guidance documents define wide ranges acceptable amounts BSM, and few include information on feedstock type age considerations. Limited exist exploring how amount affect cell performance for...

The increased use of bioretention facilities as a low impact development measure for treating stormwater runoff underscores the need to further understand their long-term function. Eventually, filter media must be (partly) replaced and disposed at end its functional lifespan. While there are several studies metal accumulation distributions in media, less is known about organic pollutant pathways these filters. present study considers occurrence 16 polycyclic aromatic hydrocarbons, 7...
