“…Strategies for better urban runoff management have been employed for years (Chao et al, 2015). Green infrastructure is widely considered in urban and regional planning processes in different parts of the world (Li and Davis, 2009;Melo dos Santos and Farias, 2017;Martí et al, 2020;Tirpak et al, 2021). This is composed of a variety of alternatives, from street trees, green walls and roofs on buildings, parks and playgrounds, and permeable pavements, walkways and parking lots, among many other examples (US EPA, 1999).…”

“…They are able to reduce runoff, mitigate its pollutants and provide aesthetic and ecological benefits (Li and Davis, 2009). They favor the development of local flora and fauna, improve water quality and infiltrate stormwater runoff, thus mitigating waterlogging problems (Tirpak et al, 2021). Although they can have different sizes and shapes, they are mainly composed of vegetation on a substrate layer, fine (sand) and coarse (gravel) granular material; occasionally, they can include drainage at their base to increase their hydraulic conductivity (Vijayaraghavan et al, 2021) (Figure 9.3).…”

In recent years, society has achieved a better quality of life; this has been possible thanks to scientific and technological advances. Among the advances that have allowed us to move forward is, without a doubt, the development of the vaccine against the SARS-CoV-2 virus. The method used for the synthesis of this vaccine was developed by Ugur Sahin and Öezlem Türeci, founders of BioNTech. Yes, behind the scientific development of greatest impact and relevance in recent years are a man and a woman. This scientific development was possible thanks to both of them, and here it is important to highlight the quality of women in science related to seeing issues from another perspective. Therefore, the union of their strengths and their differences made it possible to have a vaccine that makes it possible to return to life without confinement, without fear of going out, and with the possibility of enjoying it. Thus, the role of women in science is not only valuable, but fundamental to solve the problems that afflict us today. In this context, I can only thank and congratulate the women who today, thanks to their training, discipline and commitment, are giving us this wonderful work of science. I am sure that more challenges will come, but always counting on them, we will come out ahead. My most sincere appreciation and admiration.

“…The filtration layer in bioretention facilities takes on the role of purification, which has been proven to be efficient in removing oil [4], heavy metal [5] and pathogenic bacteria indicator species [6] from stormwater runoff. However, the performance of traditional filtration layer is not effective at removing phosphorus [7], mainly due to the leaching of phosphorus from compost (a typical filter additive in the filtration layer) [8].…”

Bioretention systems are frequently employed in stormwater treatment to reduce phosphorus pollution and prevent eutrophication. To enhance their efficiency, filter additives are required but the currently used traditional materials cannot meet the primary requirements of excellent hydraulic properties as well as outstanding release and adsorption capacities at the same time. In this research, a polyurethane-biochar crosslinked material was produced by mixing the hardwood biochar (HB) with polyurethane to improve the performance of traditional filter additives. Through basic parameter tests, the saturated water content of polyurethane-biochar crosslinked material (PCB) was doubled and the permeability coefficient of PCB increased by two orders of magnitude. Due to the polyurethane, the leaching speed of phosphorus slowed down in the batching experiments and fewer metal cations leached. Moreover, PCB could adsorb 93–206 mg/kg PO43− at a typical PO43− concentration in stormwater runoff, 1.32–1.58 times more than HB, during isothermal adsorption experiments. In the simulating column experiments, weaker hydropower reduced the PO43− leaching quantities of PCB and had a stable removal rate of 93.84% in phosphate treatment. This study demonstrates the potential use of PCB as a filter additive in a bioretention system to achieve hydraulic goals and improve phosphate adsorption capacities.

“…Using WTRs upstream provides in-stream nutrient reduction, enables the quantification of PO 4 3− removal, and provides a beneficial reuse of a waste material. There have been several approaches investigated for reducing PO 4 3− upstream such direct addition of amendments to source water, wetlands or riparian buffers [16]. For instance, Churchill et al [17] found that 5 mg/L of alum added directly to the inlet of Jameson Lake, Washington USA reduced phosphorus levels in the lake from 0.13 mg/L to below 0.02 mg/L.…”

It is well documented that excess phosphorus in source waters is a major contributor to harmful algal bloom formation. While there are many approaches to controlling algal populations in reservoirs, including a variety of phosphorus reduction approaches (e.g., sequestration of legacy phosphorus with alum or clay products), addressing physical phosphorus loading upstream is considered less often. Water treatment residuals (WTR) containing alum, a common waste product of conventional surface water treatment, have been shown to retain the ability to capture phosphorus even after the WTR ‘sludge’ is formed and removed from the sedimentation process. This research designed and tested a refillable, reusable in-stream phosphorus cartridge system which beneficially reutilizes WTR ‘sludge’ to sequester instream phosphorus and remove it from the water when spent media is replaced. This reduces in-stream phosphorus entering into the reservoir without permanently adding additional materials to the waterbody and provides measurable results as to the amount of phosphorus removed. The ten sampling events during the first year’s field assessment indicated that the gates removed a total of 556.31 g of reactive phosphorus (PO43−) and it is anticipated that the actual phosphorous removal was even greater. Other watershed managers can implement the same approach using their own WTR to capture in-stream phosphorus.
