Here we track the water microbiome daily across households in St. Louis, Missouri, alongside functional gene profiles and antimicrobial resistomes. Our results show substantial differences in species composition between households, with household identity, instead of temporal fluctuations or specific water-use devices, emerging as the dominant variable shaping microbiome composition. Using LASSO regression models, we identified informative taxa for each household, achieving an average accuracy of 97.5% in estimating a sample’s household origin. Notably, distinct profiles of opportunistic premise plumbing pathogens (OPPPs) were detected, with Mycobacterium gordonae being twice as prevalent as M. chelonae. Community assembly simulations indicated that stochastic processes primarily drive household-level taxonomic variation. In contrast, antimicrobial resistomes and functional gene repertoires were similar across households, likely influenced by common chloramine residuals applied throughout the local water distribution systems. Genes conferring resistance to beta-lactams were prevalent in bathtub faucet water across all households. These results highlight the need to incorporate household-level species variation when assessing health risks from OPPPs and monitoring antimicrobial resistance. These findings also pave the way for new research to better understand plumbing environments as potential routes for the transmission of resistant bacteria and their genes. Taxonomic compositions in bathtub faucet water microbiomes showed household individuality, with differences in the prevalences of non-tuberculous mycobacterial species. A similar antimicrobial resistome was detected.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1178-1194"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845197","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}

Current remediation strategies typically focus on either adsorption or degradation, neglecting the potential of an integrated approach. Herein, we present a pyrazolate metal–organic framework (MOF), PCN-1003, featuring a lamellar structure with one-dimensional open channels. PCN-1003 exhibits exceptional stability across a wide pH range (1–12) in aqueous solutions, achieving efficient PFOA adsorption (642 mg g−1). Mechanistic studies revealed that a PFOA–acetate exchange process dominates, representing a remarkable example of such a mechanism and enabling efficient PFOA uptake. Notably, PCN-1003 greatly facilitates PFOA degradation at a much lower temperature (90 °C) than observed in previously reported methods, with an approximately threefold catalytic acceleration effect, attributed to the coordination of PFOA and the confined environment within PCN-1003. This study pioneers integrated PFOA concentration and degradation using a single MOF, presenting a promising avenue for treating water contaminated with per- and polyfluoroalkyl substances. A robust pyrazolate metal–organic framework acts as both an adsorbent for perfluorooctanoic acid and a catalyst for degradation under mild conditions, providing an integrated approach for the capture and destruction of per- and polyfluoroalkyl substances.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1218-1225"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845239","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}

Despite the increasing per capita use of antimicrobials in Australia, surveys remain limited. Here we investigated the occurrence and use of 102 antimicrobials and their transformation products in raw wastewater collected from 50 wastewater treatment plants across Australia, encompassing ~50% of the national population. The wastewater data were subsequently correlated with catchment-matched Census data to identify population-level socioeconomic factors associated with antimicrobial use. The results showed the detection of 41 antimicrobials and 15 transformation products, covering most of the common antimicrobial groups, with 30 analytes detected at a frequency >50%. Amoxicilloic acid and cephalexin occurred at the highest concentrations and population-normalized mass loads. Correlation analysis revealed a significant association between the consumption of antimicrobials and various socioeconomic statuses, including income, education, occupation, housing, race, health condition and transport. Our study offers comprehensive insight into the patterns of antimicrobial use at the population level in Australia and highlights potential socioeconomic drivers of its use. The use of antimicrobial agents can exacerbate the proliferation of antimicrobial resistance genes, which can put public health at risk; evaluating this risk requires proper monitoring. An extensive investigation of Australian wastewater reveals a distinct correlation between the type of antimicrobial used and the socioeconomic status of the population.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1166-1177"},"PeriodicalIF":0.0,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845210","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}
