Special Issue Information

Nutrients in stormwater from urban and agricultural areas can negatively impact receiving waters, including toxic algal blooms and dead zones. There is a need to improve the understanding of the occurrence, impact, and removal of nutrients from stormwater. This Special Issue aims to explore the uptake and transport of nutrients in stormwater, the impacts of nutrients in stormwater, and how nutrients can be removed from stormwater. This may include studies from the field to watershed scales, studies evaluating the impacts of climate change on nutrient transport and transformations, modeling studies, or other studies evaluating the occurrence and impact of nutrients in stormwater. Treatment methods may include low-impact development (LID) techniques, green stormwater infrastructure, in-line treatment, or other innovative methods for the removal of nutrients from stormwater. Particular focus on nitrogen and phosphorus is encouraged, but not required.

Dear Colleagues,

Recent literature shows that many low-impact development techniques and green stormwater infrastructure can export nutrients to receiving waters. With the increased frequency of the occurrences of algal blooms, dead zones growing, and toxic algal blooms distrupting water supplies, nutrients in stormwater has become a topic that needs further exploration. The purpose of this Special Issue is to improve th understanding of the occurrence, impact, and removal of nutrients from stormwater.

We invite you to contribute papers that explore the uptake and transport of nutrients in stormwater, the impacts of nutrients in stormwater, and how nutrients can be removed from stormwater in urban and agricultural areas.  This may include studies from the field to watershed scales, studies evaluating the impact ofc climate change on nutrient transport and transformations, modeling studies, or other studies evaluating the occurrence and impact of nutrients in stormwater. Studies on innovative technologies for the removal of nutrients from stormwater are encouraged. Treatment methods can include low-impact development (LID) techniques, green stormwater infrastructure, in-line treatment, or other innovative methods for the removal of nutrients from stormwater. Particular focus on nitrogen and phosphorus is encouraged, but not required.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Low-impact development (LID) is a common management practice used to infiltrate and filter stormwater through vegetated soil systems. The pollutant reduction potential of these systems is often characterized by a single pollutant removal rate; however, the biophysical properties of soils that regulate the removal of pollutants can be highly variable depending on environmental conditions. The goal of this study was to characterize the variability of soil properties and nitrogen (N) cycling rates in bioretention facilities (BRFs). Soil properties and potential N cycling processes were measured in nine curbside bioretention facilities (BRFs) in Portland, OR during summer and winter seasons, and a subset of six sites was sampled seasonally for two consecutive years to further assess temporal variability in soil N cycling. Potential N cycling rates varied markedly across sites, seasons, and years, and higher variability in N cycling rates was observed among sites with high infiltration rates. The observed seasonal and annual changes in soil parameters suggest that nutrient removal processes in BRFs may be highly variable across sites in an urban landscape. This variability has important implications for predicting the impacts of LID on water quality through time, particularly when estimated removal rates are used as a metric to assess compliance with water quality standards that are implemented to protect downstream ecosystems.

Green stormwater infrastructure (GSI) has become increasingly common to mitigate urban stormwater runoff. However, there is limited research on the impact of age and type of GSI. This study evaluated nutrient and metals concentrations in the soil water of five different GSI systems located at the University of Portland in Portland, Oregon. The GSI systems included a bioretention curb extension (part of Portland’s Green Street project), a bioretention basin, a bioretention planter, an infiltration basin, and a bioswale ranging in age from 2 to 11 years. Samples were taken from each system during rain events over a 10-month period and analyzed for copper (Cu), zinc (Zn), phosphate (PO43−), and total phosphorus (TP). Copper and zinc concentrations were found to be impacted by GSI age, with lower concentrations in older systems. The same trend was not found with PO43− and TP, where almost all GSI systems had soil water concentrations much higher than average stormwater concentrations. Age likely played a role in phosphorus soil water concentrations, but other factors such as sources had a stronger influence. Phosphorus is likely coming from the compost in the soil mix in addition to other sources in runoff. This study shows that GSI systems can be effective for copper and zinc, but changes to the soil mix design are needed to reduce high levels of PO43− and TP in soil water. Full article
