“…This same bloom posed a minimal to moderate threat to recreation (swimming, fishing; WHO 1999), categorized as minimal (< 10 μ g microcystins L −1 , typically < 20,000 cells mL −1 ), moderate (10–20 μ g microcystins L −1 , typically 20,000–100,000 cells mL −1 ), and high (> 20 μ g microcystins L −1 , typically > 100,000 cells mL −1 ) (USEPA document 820R15100). In addition to lakes and drinking water supplies, stormwater ponds (SWPs), constructed systems that mitigate flooding, often harbor cyanoHABs, including Microcystis blooms (Lewitus et al 2003; Siegel et al 2011; Greenfield et al 2017), because they accumulate nutrients (from fertilizers, pet waste, and others) from runoff, have low flow, and long residence times, which combined frequently lead to stagnation and eutrophication (Lewitus et al 2008; Serrano and DeLorenzo 2008; Beckingham et al 2019). SWPs are common in flood‐prone regions, for example, coastal South Carolina alone has > 21,000 SWPs, with many nestled within residential neighborhoods and golf courses (Lewitus et al 2003; Smith et al 2019).…”

Cyanobacteria are responsible for the largest number of harmful algal blooms (HABs) worldwide. HABs caused by the genus Microcystis are health threats because they often occur within close proximity to humans and produce phycotoxins such as microcystins that can contaminate drinking water and recreational areas. Molecular techniques enable accurate and rapid (~ 1 h) HAB detection that facilitates monitoring, “early warnings” of blooms, and corresponding management responses. Sandwich hybridization assay (SHA), the technique considered here, directly (no amplification) identifies and quantifies plankton species using ribosomal RNA (rRNA)‐targeted oligonucleotides. This project focused on the development of a new SHA method for the detection of Microcystis (16S rRNA) using laboratory cultures. Assay calibration curve and limits of detection were determined using Microcystis aeruginosa, though signal intensity differed significantly (p < 0.05) between three species (M. aeruginosa, Microcystis botrys, Microcystis wesenbergii). SHA results for M. aeruginosa raised under three light intensities (40, 60, and 100 μmol photons m−2 s−1) and two temperatures (25°C and 32°C) were greatest at the highest irradiance for both temperatures, but otherwise variable, yielding an overall significant (p < 0.05) interaction between light and temperature. The 32°C treatment also resulted in significantly lower (p < 0.05) Photosystem II quantum efficiency (Fv/Fm) and microcystins concentrations per light intensity. Spiked field experiments showed that SHA signal was not significantly affected (p > 0.05) by a mixed phytoplankton assemblage. The assay speed, wide detection range, and specificity indicate that this method has promise for additional field studies and HAB monitoring.

“…A large single pond will perform differently under identical conditions compared to multiple, in‐series ponds. This will ultimately impact the nitrogen and phosphorus cycle differently as sedimentation rates within the ponds highly impacted the amount of carbon and nitrogen sequestration via burial (Beckingham, Callahan, & Vulava, 2019). Ahilan et al (2019) utilized the Revitalized Flood Hydrographs rainfall model and the layer‐based hydro‐morphodynamic model to model suspended sedimentological effects.…”

This review summarizes over 280 studies published in 2019 related to the characterization, control, and management of urban stormwater runoff. A summary of quantity and quality concerns is provided in the first section of the review, serving as the foundation for the following sections which focus on the control and treatment of stormwater runoff. Finally, the impact of stormwater control devices at the watershed scale is discussed. Each section provides a self-contained overview of the 2019 literature, common themes, and future work. Several themes emerged from the 2019 literature including exploration of substrate amendments for improved water quality effluent from stormwater controls, the continued study of the role of vegetation in green infrastructure practices, and a call to action for the development of new models which generate reliable, computationally efficient results under the physical, chemical, biological, and social complexity of stormwater management. © 2020 Water Environment Federation • Practitioner points • Over 280 studies were published in 2019 related to the characterization, control, and treatment of urban stormwater. • Studies on bioretention and general stormwater characteristics represented the two most common subtopics in 2019. • Trends in 2019 included novel substrate amendments, studies on the role of vegetation, and advancements in computational models.

“…Gold et al [3] observed little to no improvement in downstream water quality and nutrient concentrations after watershed-scale implementation of wet stormwater ponds in an urbanizing coastal area. A growing number of researchers are recognizing that in-pond nutrient cycling may make urban stormwater ponds function as sources of dissolved nutrients [31,32], and there is a need for new research that investigates the mechanistic controls on nutrient cycling and downstream fate in these urban features of the built environment. We provide evidence here of the dynamic nature of in-pond DON and PON, and future studies should investigate this across temporal and spatial scales and in environments with varying ON sources such as with different types of vegetation.…”

Wet season nitrogen export from a residential stormwater pond

Stormwater runoff is recognized as a cause of water quality degradation because it may carry nitrogen (N) and other pollutants to aquatic ecosystems. Stormwater ponds are a stormwater control measure often used to manage stormwater runoff by holding a permanent pool of water, which reduces the peak flow, magnitude of runoff volume, and concentrations of nutrients and pollutants. We instrumented the outlet of a stormwater pond in an urban residential neighbourhood in Florida, United States to (1) investigate the concentration and composition of N forms during the summer rainy season (May to September 2016), and (2) determine the bioavailability of organic N in the stormwater pond with a bioassay experiment. A total of 144 outflow water samples over 13 storm events were collected at the outlet of the stormwater pond that collects runoff from the residential catchment. Samples were analysed for various inorganic N [ammonium (NH 4-N), nitrate (NO 3-N)], and organic N forms [dissolved organic nitrogen (DON), and particulate organic nitrogen (PON)]. Flowweighted mean concentration of total N (TN) in pond outflow for all collected storm events was 1.3±1.42 mg L-1 , with DON as the dominant form (78%), followed by PON and NO 3-N (each at 8%), and NH 4-N (6%). In the bioassay experiment, organic N (DON+PON) was significantly decreased by 25-28% after 5 days of incubation, suggesting that a portion of the DON carried from the pond outflow to receiving water bodies may be bioavailable. These results suggest that efforts to mitigate stormwater N outflows from urban ponds should incorporate both inorganic and organic N in management plans.
