“…The sediments from the SWRPs and the small, shallow lakes contained PAH at a wide range of concentrations ( Figure 2). The PAH levels in the SWRP were similar to what has been reported for comparable systems [37][38][39], and the concentrations in the lakes were in the upper range of what has been reported for freshwater sediments [40,41]. There was some variation from site to site in the PAH concentrations in both types of sediments.…”

Sediments and invertebrates were sampled from 9 stormwater retention ponds (SWRPs) and 11 natural, shallow lakes in Denmark. Samples were analyzed for 13 polycyclic aromatic hydrocarbons (PAHs). The SWRPs received urban and highway runoff from various types of drainage areas and the lakes were located in areas of various land uses. Comparing PAHs in the sediments of the SWRPs and the lakes, it was found that levels of total PAH were similar in the two aquatic systems, with median values of 0.94 and 0.63 mg·(kg·DM)−1 in sediments of SWRPs and lakes, respectively. However, the SWRP sediments tended to have higher concentrations of high-molecular-weight PAHs than the lakes. A similar pattern was seen for PAHs accumulated in invertebrates where the median of total PAH was 2.8 and 2.1 mg·(kg·DM)−1 for SWRPs and lakes, respectively. Principal component analysis on the PAH distribution in the sediments and invertebrates showed that ponds receiving highway runoff clustered with lakes in forests and farmland. The same was the case for some of the ponds receiving runoff from residential areas. Overall, results showed that sediment PAH levels in all SWRPs receiving runoff from highways were similar to the levels found in some of the investigated natural, shallow lakes, as were the sediment PAH levels from some of the residential SWRPs. Furthermore, there was no systematic trend that one type of water body exceeded environmental quality standards (EQS) values more often than others. Together this indicates that at least some SWRPs can sustain an invertebrate ecosystem without the organisms experiencing higher bioaccumulation of PAHs then what is the case in shallow lakes of the same region.

“…Stormwater controls can mitigate the impacts of runoff on the receiving environment through sedimentation , adsorption, filtration, biodegradation, and plant uptake . Treatment efficacy of swales and basins have been studied through experimentation ,,,,,− and modeling, ,,,,, and results are variable, with TSS removal through grass swales ranging from negative removal to nearly 100% . Many factors contribute to removal efficacy of swales (e.g., infiltration rate and vegetation) and basins (e.g., surface area and storage volume) making removal efficacies site-specific with large uncertainty ranges (section S4.3 of the Suppporting Information).…”

“…This contamination poses local environmental and health risks because many stormwater pollutants exhibit toxicity, and chronic and acute illnesses can be traced to runoff via exposure through drinking water, seafood, and recreation . Recognition of the potentially dangerous effects of stormwater runoff has prompted drainage system components that were originally designed for flow attenuation (e.g., swales and basins) to now be considered for their water quality benefits; therefore, the fate and transport of pollutants through stormwater treatment devices such as swales − and basins − has been the subject of recent research. Globally, construction and maintenance of drainage system components require materials (e.g., concrete), equipment operation (e.g., excavator), transportation (e.g., hauling of materials and equipment), and disposal (e.g., landfilling), all of which contribute to global environmental impacts (e.g., climate change) throughout the system’s life cycle.…”

Roadway drainage design has traditionally focused on cost-effectively managing water quantity; however, runoff carries pollutants, posing risks to the local environment and public health. Additionally, construction and maintenance incur costs and contribute to global environmental impacts. While life cycle assessment (LCA) can potentially capture local and global environmental impacts of roadway drainage and other stormwater systems, LCA methodology must be evaluated because stormwater systems differ from wastewater and drinking water systems to which LCA is more frequently applied. To this end, this research developed a comprehensive model linking roadway drainage design parameters to LCA and life cycle costing (LCC) under uncertainty. This framework was applied to 10 highway drainage projects to evaluate LCA methodological choices by characterizing environmental and economic impacts of drainage projects and individual components (basin, bioswale, culvert, grass swale, storm sewer, and pipe underdrain). The relative impacts of drainage components varied based on functional unit choice. LCA inventory cutoff criteria evaluation showed the potential for cost-based criteria, which performed better than mass-based criteria. Finally, the local aquatic benefits of grass swales and bioswales offset global environmental impacts for four impact categories, highlighting the need to explicitly consider local impacts (i.e., direct emissions) when evaluating drainage technologies.

“…Particle size is an important indicator to assessing water quality, and it can be related to several characteristics of pollutants for wastewater treatment, such as settleability, turbidity, growth of microorganisms, and absorption/adsorption capacity of adsorbents. Smaller particles with high organic content can adsorb more pollutants, such as heavy metals, polynuclear aromatic hydrocarbons, emerging contaminants, and/or chlorinated pesticides (e.g., DDT) (Bentzen and Larsen, 2009;Han et al, 2006;Liu et al, 2009;Schorer, 1997). Particle size analysis also has been used to evaluate the performance of filtration and optimize UV disinfection systems (Bourgeous et al, 2003) and is being used extensively in stormwater management (Li et al, 2005).…”

Hydrated iron oxide supported on resin (D301) was prepared as a new sorbent for the removal of glyphosate from wastewater. Batch adsorption studies were performed on glyphosate aqueous solutions with different initial glyphosate concentrations and temperatures. Experimental data were analyzed using the Langmuir and Freundlich isotherms, and the adsorption data were best fit to the Langmuir isotherm model. The thermodynamic parameters AG, JH, and AS also were calculated for the adsorption processes. Adsorption rate constants were determined using the pseudo-first-order and pseudosecond-order rate equations and Kannan-Sundaram intraparticle diffusion models. Adsorption of glyphosate clearly followed the pseudo-second-order model and was controlled by both film diffusion and intraparticle diffusion. Water Environ. Res., 83, 784 (2011).
