Here we applied hybrid-capture viral metagenomics to 127 weekly 24-h composite influent samples from a single sentinel wastewater treatment plant in Leuven, Belgium, collected over 31 months, and linked wastewater time series to national clinical indicators of multiple pathogens. Our approach recovered a genome-resolved target-enriched virome spanning 339 viral species and 715 strains, captured seasonal community turnover and showed that rotavirus A in wastewater typically preceded clinical surveillance by ~1 week. It also identified signals beyond routine wastewater programmes, notably a parvovirus B19 surge starting in April 2023, about 1 year before the national public health alert. Overall, here we show that longitudinal hybrid-capture metagenomics can extend wastewater surveillance from detection to strain-resolved, multi-virus epidemiology and can provide early circulation signals for clinically relevant viruses. Using hybrid-capture metagenomics, an analysis of 31 months of wastewater samples detected 339 viral species and 715 strains, retrospectively tracked seasonal trends and provided early warnings of clinically relevant outbreaks, including rotavirus A and parvovirus B19.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 9","pages":"1128-1138"},"PeriodicalIF":30.7,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981502","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}

To elucidate mechanisms and pathways towards deeper defluorination, we analysed products across three legacy PFAS structural families under UV/sulfite conditions. The specific fluorocarbon undergoes sequential reactions with an eaq−, a hydroxyl radical (HO•) and hydroxide ions (HO−), resulting in C–C cleavage. The carboxylate group in the fragmented products is critical for further defluorination. Beyond preserving eaq−, high pH enhances PFAS degradation by promoting the fragmentation and C=C formation. The findings substantially expand the mechanistic scheme, explain the puzzling products previously observed and correct the common misinterpretation of chain-shortening from RF–CF2–COO− to RF–COO−. The primary product is formate rather than CO2 or CO. This study advances fundamental insights for (1) tackling PFAS pollution and (2) designing readily degradable fluorochemicals. This study elucidates the defluorination mechanism and pathways of per- and polyfluoroalkyl substances in ultraviolet/sulfite systems, emphasizing the coupling roles of hydrated electrons, hydroxyl radicals and hydroxide ions.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 9","pages":"1177-1189"},"PeriodicalIF":30.7,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981558","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}

Outdoor experiments demonstrate that ASP delivers a peak power output of 154.7 W, with a daily water collection rate of 19.82 kg m−2, alongside lithium and uranium extraction capacities of 4.50 mmol m−2 and 2.64 μmol m−2, respectively. Economic analysis indicates that ASP can maintain an annual net income exceeding US$20 m−2.

However, recovering conjugative plasmids from complex communities remains challenging because both plasmid extraction and cultivation-based approaches introduce bias. Here we show that filter mating coupled with nanopore selective sequencing (FM-NSS) can recover an ampicillin-selected, recipient-compatible fraction of conjugative plasmids from a full-scale WWTP without plasmid extraction. After depletion of reads aligning to the Escherichia coli recipient genome, FM-NSS recovered a total of 1.10 million plasmid reads. De novo assembly yielded 622 non-redundant plasmid contigs, including 441 not detected by extraction-based plasmid sequencing from the same conjugant pools. Notably, activated sludge displayed a distinct recovered plasmid profile compared with other treatment stages, which is associated with an elevated estimation of community replication rates. FM-NSS provides a practical workflow to expand the recovery of selected conjugative plasmids from complex environmental communities. Filter mating coupled with nanopore selective sequencing recovers recipient-compatible conjugative plasmids from wastewater without plasmid extraction, revealing greater plasmid diversity and stage-specific profiles than extraction-based sequencing.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 9","pages":"1100-1113"},"PeriodicalIF":30.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981563","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}

Here we show that ultraviolet (UV) irradiation-induced localized surface plasmon resonance drives reductive defluorination of perfluorooctanoic acid and perfluorooctane sulfonic acid, two legacy contaminants. Stable, quantum-sized palladium and platinum nanocatalysts supported on aminated mesoporous silica nanoparticles (MSN–NH2–Pd and MSN–NH2–Pt) transform perfluorooctanoic acid and perfluorooctane sulfonic acid with stoichiometric, or near-stoichiometric, fluoride release under low-intensity UVC or UVA irradiation at room temperature. Time-resolved 19F nuclear magnetic resonance, high-resolution mass spectrometry and complementary analyses indicate a stepwise reductive hydrodefluorination pathway in which oxidized, short-chain products do not measurably accumulate under the conditions studied. Scavenger and control experiments are consistent with hydrated electrons and in situ hydrogen generation as key reactive species. Taken together, the results indicate that synergistic interfacial PFAS sorption, plasmon-induced hydrogen evolution and hydrated electron formation drive PFAS defluorination under mild reaction conditions. This study demonstrates that plasmon-enabled photocatalysis can break down PFAS at room temperature with minimal inputs, achieving complete or near-complete defluorination through mechanisms involving plasmon-driven hydrogen production and hydrated electrons.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 9","pages":"1166-1176"},"PeriodicalIF":30.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44221-026-00690-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981573","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}

This study breaks the norm and proposes a new strategy for synchronous separation and parallel treatment of opposing emulsion using heterogeneous wetting membranes. Here the membrane features spatially distributed hydrophilic/hydrophobic regions, combined with a bidirectional gradient contraction channel module, enabling a single device to synchronously and continuously separate opposing emulsion, such as oil-in-water (O/W) and water-in-oil (W/O) emulsions. The non-uniform shear field of the gradient contraction channel destabilizes emulsion droplets and enables gradual demulsification at the membrane interface. Membrane with patterned wettability guides the dispersion to migrate in the opposite direction, coupled with shear demulsification and directional phase transport. The two-phase separation efficiency of this mechanism exceeds 99.9%, and its anti-fouling performance and long-term stability have been notably enhanced. This work establishes a new paradigm for synchronous separation and parallel processing of opposite emulsions, paving the way for efficient integrated oil–water separation technology. A heterogeneous wetting membrane integrated with bidirectional gradient contraction channels enables the synchronous and continuous separation and parallel processing of opposing oil-in-water and water-in-oil emulsions with over 99.9% efficiency while delivering enhanced anti-fouling performance and long-term operational stability.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1318-1329"},"PeriodicalIF":30.7,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190081","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}

Mitigating DBP formation without compromising microbial safety remains a critical challenge. Here we developed DISoptimizer, a water-quality-adaptive optimization framework designed to determine the optimal chlorine dose across heterogeneous water matrices, thereby maintaining a user-defined residual chlorine target as an operational surrogate for disinfection reliability while minimizing four trihalomethane (THM4) formation. Using machine learning models trained on experimental datasets covering diverse water quality conditions, DISoptimizer predicts residual chlorine and THM4 formation after 24 h, representing the point of delivery. Crucially, DISoptimizer incorporates a weighting factor to encode user-defined preferences, allowing utilities to adjust the operational emphasis on maintaining residual chlorine margins versus mitigating THM4 formation in response to fluctuating water quality and different management priorities. Computational simulations coupled with external validation demonstrated that DISoptimizer achieved a 5–35% reduction in THM4 formation compared to the empirical fixed-dosing strategies, while consistently maintaining residual chlorine margins. This work advances disinfection management from DBP concentration prediction towards proactive chlorine-dosing decisions, supporting the management of health risks associated with microbial contamination and DBP exposure in drinking water. A machine learning-based framework is designed to adaptively optimize chlorine dosing across diverse water conditions to maintain disinfection reliability while reducing the formation of carcinogenic disinfection by-products.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1330-1342"},"PeriodicalIF":30.7,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190082","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}
