“…To our knowledge, the only possible exception is a new treatment train technique called Regenerative Stormwater Conveyance (RSC), which uses a series of step-pools and subsurface geomedia to detain and treat stormwater, e.g., [33]. Experimental RSC systems show promise in restoring pre-development hydrographs and attenuating some contaminants [34,35], but do not yet prescribe specific hydraulic residence times to optimize contaminant removal. As a result, RSC systems can, at times, fail to reduce nitrate concentrations and be inactivated by groundwater upwelling [33].…”

Green infrastructure is an increasingly popular approach to mitigate widespread degradation of urban waters from stormwater pollution. However, many stormwater best management practices (BMPs) have inconsistent water quality performance and are limited to on-site, land-based deployments. To address basin-wide pollutant loads still reaching urban streams, hyporheic zone engineering has been proposed as an in-stream treatment strategy. Recognizing that regulator and practitioner perspectives are essential for innovation in the water sector, we interviewed U.S. water management professionals about the perceived risks, opportunities, and knowledge gaps related to in-stream stormwater treatment. We used engineered hyporheic zones as a case study to understand interviewee perspectives on an emerging class of in-stream treatment technologies. Interviews revealed that many considerations for in-stream stormwater treatment are common to land-based BMPs, but in-stream BMPs have additional unique design and siting requirements. Here, we synthesize practitioner goals, their recommendations on in-stream BMP design, and open research questions related to in-stream BMPs. Many interviewees suggested pairing engineered hyporheic zones with other BMPs in a treatment train to improve in-stream treatment, while simultaneously reducing risk and cost. We discuss how treatment trains and other strategies might also help overcome regulatory hurdles for innovative stormwater treatment.

“…The total phosphorus (TP) present in the runoff can range between 0.08 and 17.9 mg/L (Koryto et al, 2018; Paule‐Mercado et al, 2016; Zinger et al, 2013). Even if phosphorus concentrations in urban runoff are relatively low, the cumulative loads on receiving waters can be quite high because of the large volumes of runoff from urban impervious surfaces.…”

In this study, laboratory models of six permeable pavement system (PPS) columns with various subbase configurations were examined for phosphorus attenuation.Experiments were carried out under varying intensities and durations of rainfall to investigate possible PPS modifications to enhance the performance of phosphorus attenuation and the likelihood of phosphorus leaching back to infiltration.

This review summarizes over 250 studies published in 2018 related to the characterization, control, and management of urban stormwater runoff. The review covers three broad themes: (a) quantity and quality characterization of stormwater, (b) control and treatment of stormwater runoff, and (c) implementation and assessment of watershed‐scale green stormwater infrastructure (GSI). Each section provides an overview of the 2018 literature, common themes, and future work. Several themes emerged from the 2018 literature including exploration of contaminants of emerging concern within stormwater systems, characterization and incorporation of vegetation‐driven dynamics in stormwater control measures, and the need for interdisciplinary perspectives on the implementation and assessment of GSI.Practitioner points Over 250 studies were published in 2018 related to the characterization, control, and treatment of stormwater. Studies cover general stormwater characteristics, control and treatment systems, and watershed‐scale assessments. Trends in 2018 include treatment trains, vegetation dynamics, and interdisciplinary perspectives.
