“…The sediment that accumulated in the inflow pipe had an organic matter content of 290 AE 19 g=kg of dry mass (or 29.0% AE 1.9%, n ¼ 3), which is above the range previously reported for sediments from other infiltration basins (66-223 g=kg of dry mass) (Durand et al 2005;Murakami et al 2008;Coulon et al 2013). One explanation for the higher-than-reported organic matter content was the removal of low organic matter content sediment from the stormwater runoff prior to entering the infiltration trench.…”

Infiltration trenches are one type of stormwater control measure (SCM) that can help fulfill stormwater management requirements, especially in highly urban areas where open space is limited. Underground infiltration trenches built without pretreatment have a high risk of clogging and subsequent decrease in the rate of stormwater exfiltration from the system. The focus of this study was to assess the cause of failure of an underdesigned infiltration trench without pretreatment that experienced diminished performance after only 1 year of operation. The system was excavated after 11 years of operation and subsequently analyzed for failure using particle size distribution analysis, in-situ infiltration tests, capillary flow analysis to assess geotextile clogging, and soil extractions to quantify metals accumulation. Results indicate that the decrease in infiltration trench performance was caused by a combination of three clogging mechanisms: (1) sediments with a median particle size (D 50 ) of 26.4 μm and a high percentage (52%) of silt-sized particles clogged the perforated inflow pipe, which minimized the amount of stormwater runoff able to enter the trench; (2) stormwater sediments that accumulated in the trench itself created a filter cake on top of the geotextile (i.e., blinding), which minimized exfiltration of stormwater from the trench; and (3) clay-sized particles present in the stormwater sediments migrated through the geotextile and accumulated on the geotextile-subsurface interface, which reduced the permeability of the soil just below the geotextile. These results outlining specific failure mechanisms provide valuable information regarding maintenance requirements for current infiltration trench operation as well as for future infiltration trench SCM design.

“…This result could be explained by the nature of the organic matter present in the sediments. As described in previous studies [11,27,34], the organic matter of stormwater sediments is attributed to both natural and anthropogenic contributions, related to the development of vegetation and to the nature of organic matter in runoff waters. Anthropogenic organic matter may originate from oil and fuels as well as from vehicle and infrastructure corrosion (tyre and road fragments) [35].…”

The management of stormwater sediment is a key issue for local authorities due to the pollution load and significant tonnages. In view of reuse, for example for civil engineering, the environmental evaluation of these highly aggregated sediments requires the study of the fractionation and mobility of trace metals. The distribution of trace metals (Cd, Cr, Cu, Ni, Pb, Zn) and their level of lability in three French stormwater sediments was determined using sequential and kinetic extractions (EDTA reagent) associated with mineralogical analysis and scanning electron microscopy observations. Using microanalysis, new data were acquired on the evolution of aggregate state during extractions, and on its significant role in the retention of trace metals. Trace metals were, in particular, observed to be very stable in small aggregates (10-50 microm). Comparison of the two extraction methods revealed that EDTA extraction was not convenient for evaluating the stable fraction of Cr, Ni and Zn. Moreover, the results were relevant for basins presenting similar sources of trace metals, whatever the physicochemical conditions in basins. The results suggest that the management of stormwater sediments could be improved by a better knowledge of metal mobility, as chemical extractions could highlight the localization of the mobile fraction of trace metals. Treatment could be therefore avoided, or specific treatment could be applied to a reduced volume of sediments.

“…Cfb. In this climatology, the retention of contaminants [140,141] such as hydrocarbons [142] and heavy metals [143] or bacterial contamination [144] has also been proven, although not all contaminants behave in the same way; some are not retained in high concentrations [145,146], and components such as carbendazim, diuron, fluopyram, imidacloprid, and lamotrigine reach the groundwater [147]. The use of vegetation such as Phalaris arundinacea and Typha latifolia can absorb or modify the mobility of heavy metals [148].…”

Urban green infrastructure such as sustainable urban drainage systems are potential providers of ecosystem services. This paper reviews the field studies that empirically verify the potential benefits of SUDS. The cultural, provisioning, supporting, and regulating ecosystem services investigated in real cases have been studied and classified according to climatology (except for the control of urban hydrology, which has been widely corroborated). Although successful cases of runoff decontamination are numerous, there is heterogeneity in the results of the systems beyond those associated with climatic differences. The other ecosystem services have not been as widely studied, giving very variable and even negative results in some cases such as climate change control (in some instances, these techniques can emit greenhouse gases). Installations in temperate climates are, by far, the most studied. These services derive from the biological processes developed in green infrastructure and they depend on climate, so it would be advisable to carry out specific studies that could serve as the basis for a design that optimizes potential ecosystem services, avoiding possible disservices.
