This study systematically reviews stormwater treatment systems to assess their effectiveness in OMP removal and their potential to mitigate associated risks. Among nature-based solutions (NBS), biofilters demonstrate high removal efficiency (&gt;80%) for most tested OMPs. A significant positive correlation was found between hydrophobicity (log <em>K</em><small><sub>ow</sub></small>) and removal efficiency (<em>p</em> &lt; 0.05; Pearson and Spearman correlation), suggesting adsorption as the dominant mechanism for hydrophobic compounds, while biodegradation plays a key role in removing many hydrophilic OMPs. Key design features, such as vegetation, submerged zones, and filter media amendments (<em>e.g.</em>, biochar, compost), further enhance treatment performance. Constructed wetlands generally achieve removal rates above 60% mainly for hydrophobic OMPs, though challenges remain for emerging refractory pollutants such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Porous pavements are effective for polycyclic aromatic hydrocarbons (PAHs) and total petroleum hydrocarbons (TPHs), particularly with adsorptive materials and geotextile layers, but limited studies restrict broader implementation. Ponds and swales exhibit variable performance, effectively treating PAHs and pesticides but showing lower efficiency for pharmaceuticals and plasticizers. Advanced oxidation technologies demonstrate strong potential, achieving &gt;80% removal for tested PAHs, pesticides and corrosion inhibitors within minutes to hours, making them suitable for post-treatment applications. Despite progress, data gaps hinder robust assessments of design and operational parameters. Future research should focus on optimizing nature-based solutions (NBS) through smart sensors, real-time control strategies, and hybrid approaches integrating advanced oxidation technologies to enhance OMPs removal in stormwater harvesting systems.</p>","PeriodicalId":75,"journal":{"name":"Environmental Science: Water Research & Technology","volume":" 10","pages":" 2274-2294"},"PeriodicalIF":3.1,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ew/d5ew00306g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145134968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the high specific surface area demand of CWs remains a limiting factor, particularly in urban areas. As the removal of organic and inorganic pollutants is predominantly influenced by the removal mechanisms associated with the selected substrate/adsorbents, this study aims to optimise these processes by hybridising different adsorbents such as biochar, granular activated carbon (GAC) and natural zeolite. Over a period of 18 months, five different approaches were tested, with modifications made to the various layers of the respective CW. Furthermore, the heavy metal (HM) speciation, the behaviour of pollutants and the changing environmental conditions within the wetlands were observed at different filter depths to determine the removal potential of the different adsorbents. The results indicated that the modified CW with biochar, zeolite, and GAC enabled high removal rates of bulk organics (91%) and HMs (Cd: 32%, Cr: 86%, Cu: 92%, Fe: 83%, Ni: 91%, Pb: 43%, and Zn: 96%) with significantly lower hydraulic retention time (HRT) compared to previous studies. This addresses the specific surface area as the main issue of these systems. It was also demonstrated that effective pre-treatment is crucial for maximizing the removal ability of CW systems. Thus, the use of these systems as a polishing technology for the downstream treatment of municipal wastewater is recommended.</p>","PeriodicalId":75,"journal":{"name":"Environmental Science: Water Research & Technology","volume":" 9","pages":" 2248-2264"},"PeriodicalIF":3.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ew/d4ew00870g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
