Here we introduce a framework that aggregates individual lake hypsography and functional attributes into composite lakes globally, across climate zones or 1-degree Earth system grid cells. We find that globally, lake shape mirrors land rather than ocean, with shallow areas dominating. This structure reveals systematic differences between glaciated and non-glaciated regions and between colder and warmer climate zones. At the 1-degree Earth system grid cells, composite lakes group into five distinct clusters. Globally, an estimated 43% of lake volume and sediment surface area lie within the mixed layer. A composite mixed layer volume-to-sediment-surface-area ratio reveals dominant water column influence and biogeochemical sensitivities, with strong contrasts across climates and glacial histories. The proposed framework advances quantifying and understanding the collective role of lakes across spatial scales in Earthʼs system. This Analysis presents a new framework that integrates lake hypsography and functional attributes at global and climatic scales, revealing key patterns in lake ecosystems and their responses to climate impacts.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 7","pages":"818-830"},"PeriodicalIF":24.1,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12279543/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a low-cost and self-supporting wooden electrode with pulsed excitation of ambient air and Fe3+ reduction, overcoming all the above issues in electro-Fenton processes. The electrode was fabricated via controlled wood delignification and carbonization, transforming into a self-supporting porous and functionalized architecture for efficient oxygen capture from air and two-electron reduction to H2O2. Periodic positive voltage pulses restored iron species from the electrode for in situ generation of radicals, minimizing surface iron accumulation and securing periodical electrode refreshing. A scaled-up system maintains a long-term operation in 30 days for bisphenol A removal without a performance loss at a low energy consumption of 0.013 kWh per gram of bisphenol A. This wooden-pulsed electro-Fenton system provides a low-cost and sustainable solution to practical wastewater treatment. The pulsed electrochemical method, combined with a wood-based electrode, enables the simultaneous reduction of oxygen to generate hydrogen peroxide and the regeneration of Fe3+ to active Fe2+ for radical production. This approach offers a cost-effective and sustainable electro-Fenton process for wastewater treatment.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 8","pages":"890-901"},"PeriodicalIF":24.1,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145123157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used 2018–2022 data from the US Water Quality Portal to compare station locations to metrics from the US Centers for Disease Control Social Vulnerability Index (SVI) and hydrography from the US Geological Survey. Statistical analyses revealed a substantial imbalance in the distribution of active monitoring station placements, with more monitoring stations in lower vulnerability areas and fewer in high vulnerability areas, and patterns that vary by state. Stations were clustered in areas of similar SVI values; areas were less likely to be monitored if they were near tracts with differing SVI values. Water quality monitoring stations are crucial to ensure a timely response to any problem emerging across water resource networks. A study of nutrient monitoring of surface waters in the South Atlantic-Gulf region shows an inhomogeneous monitoring station distribution, with fewer stations in highly vulnerable areas.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 7","pages":"831-840"},"PeriodicalIF":24.1,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research has suffered from data limitations including reliance on area-level data and small sample sizes. We address these limitations with American Community Survey restricted microdata. These individual- and household-level data permit us to assess social inequalities, including those related to intra-household demographic heterogeneity, in an incomplete plumbing border-wide analysis in the United States and by residence in a colonia (informal peri-urban settlements) versus non-colonia. We use restricted individual and household data for 2015–2019 (n = 145,500) with fine-scale geographic identifiers to locate households within/outside community water system and colonia boundaries. We employed multilevel mixed-effects logistic regression models. Half a percent of households had incomplete plumbing. Households without any non-Latinx white member and those with only foreign-born non-citizen members had greater odds of incomplete plumbing. Non-English-proficient households were more likely to experience incomplete plumbing. Additionally, incomplete plumbing was associated with disability, working age, poverty and home ownership. There were more inequalities outside of colonias than within them. This Article documents the unequal nature of plumbing poverty in the borderlands. Future initiatives and planning efforts must consider the specific inequalities experienced there to reduce plumbing poverty in the region. Incomplete plumbing affects over a million people in the USA. Analysis of individual and household data for the 2015–2019 period from the US–Mexico border reveals the unequal nature of plumbing poverty in the borderlands and provides insight for future planning.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 7","pages":"793-805"},"PeriodicalIF":24.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MNPs act as carriers for pathogens, potentially exacerbating transmission risks and endangering both aquatic ecosystems and human health. Moreover, their synergy with emerging contaminants amplifies contaminant persistence and bioavailability, warranting a deeper understanding of these implications for water security. We outline strategies for assessing the contributions of MNPs and implementing regulatory frameworks to mitigate their indirect effects. To manage these interactions under fluctuating environmental variables, advanced water treatment, modular control strategies, and early warning are essential. A holistic approach involving research, innovation and policy is imperative to protect water quality from MNPs-related impacts.

Siderophores are a prevalent strategy for iron acquisition among many bacteria, and recent evidence has suggested the potential role of siderophore-Fe3+ as bioavailable iron sources to anammox bacteria. Nonetheless, what target siderophore anammox bacteria can use and how they use it remain poorly understood. Here we shed fresh light on siderophore selectively promoting iron uptake and regulating the metabolic activity of anammox bacteria. Batch experiments and long-term operations demonstrated that siderophores catechin (CAT) and N-hydroxyethyl ethylenediamine triacetic acid (HEDTA) increased the iron uptake efficiency of anammox consortia up to 50%–65% and triggered the cofactors synthesis for key enzymes assembly, thereby selectively enhancing the anammox activity (≥350 mg N per gram of volatile suspended solids per day) and nitrogen removal efficiency (≥85%). Integrated with multi-omics approaches, we revealed versatile iron uptake pathways within anammox bacteria genera: Candidatus Brocadia acquired CAT-Fe3+ and HEDTA-Fe3+ via outer membrane receptors FitA/TbpA and FecA, respectively, whereas Candidatus Jettenia initially reduced CAT-Fe3+ using NfnB enzyme before uptake via the FeoABC system. This work reveals a pivotal role of siderophores in selectively enhancing anammox bacteria by optimizing their iron uptake and utilization and uncovers the involved molecular mechanisms, which opens promising avenues to optimize the anammox process with siderophore regulation for more efficient and sustainable wastewater treatment. The functional bacteria in the anaerobic ammonium oxidation process rely heavily on iron for their metabolism. The addition of exogenous siderophores considerably enhanced the iron uptake efficiency of anammox consortia, leading to enhanced anammox activity and nitrogen removal performance.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 7","pages":"806-817"},"PeriodicalIF":24.1,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
