We assessed four freshwater lakes along an anthropogenic impact gradient per the environmental surveillance recommendations of the Tricycle Protocol using membrane filtration with TBX agar supplemented with ceftriaxone (TBX-CRO) and Colilert Quanti-Trays (CQT-CRO) supplemented with the same. ESBL-Ec abundance and prevalence, and ESBL-Ec to E. coli ratios were significantly higher in the two highly impacted lakes; however, in the “pristine” bird sanctuary lake, ESBL-Ec were also present. The CQT-CRO format yielded reasonable qualitative (K = 0.603) and quantitative agreement (intraclass correlation coefficient = 0.849) with the TBX-CRO format. Based on random testing of a single colony per sample, CRO performed poorly for screening the ESBL phenotype among E. coli environmental isolates. Notably, ESBL-Ec isolates were not associated with an increased number of resistance phenotypes compared with non-ESBL isolates. Instead, the number of resistance phenotypes was associated with the lake from which the sample was collected. Our experience suggests when ESBL-Ec are abundant, such as in high-burden settings, the usefulness of the phenotype as a proxy for antimicrobial resistance in the environment is greatly diminished.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1321–1330 1321–1330"},"PeriodicalIF":4.8,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608775","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}

They are the predominant lotic ecosystem in the United States Southeastern Coastal Plain, a region experiencing some of the nation’s highest rates of development. This study assessed variability in DOM concentration and composition across forested to urbanized blackwater systems in coastal South Carolina, U.S. Dissolved organic carbon and nutrient concentrations as well as absorbance and fluorescence optical properties reveal that urban sites have lower concentrations, elemental ratios, and less complex DOM. In contrast, forested blackwater sites have concentrations an order of magnitude higher, elevated elemental ratios, and molecular size dominated by refractory terrestrial-like DOM. Urban blackwater rivers were observed to have DOM concentrations and composition more similar to brown water systems than rural blackwater systems. These findings suggest that the urbanization of blackwater ecosystems results in lower concentrations and the export of simpler, more labile DOM, potentially lowering dissolved oxygen concentrations, increasing atmospheric carbon emissions and other negative impacts. To protect blackwater systems, baseline DOM concentrations and composition must be established to decipher impacts on water quality due to naturally occurring versus anthropogenic activities and to properly assign classifications to these diverse systems across the U.S.Dissolved organic matter (DOM) composition was examined across blackwater coastal ecosystems, revealing transformations in DOM content associated with urbanization with implications for water quality and policy.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1281–1294 1281–1294"},"PeriodicalIF":4.8,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c01054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608848","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}

However, it is uncertain whether copper can effectively inhibit antibiotic-resistant bacterial (ARB) biofilm formation, which is crucial for water supply safety. This study examined the difference in biofilm formation between ARB and antibiotic-sensitive bacteria (ASB) on copper surfaces by measuring the extracellular polymeric substance (EPS) content. In the blank control group, ASB biofilms outperformed ARB biofilms; however, when exposed to copper, the bacterial abundance of ARB biofilms was 100.5–101.0 times higher than that of ASB biofilms, and the EPS content was also 101.1–101.9 times higher. This disparity was mainly attributed to the varying fitness costs of the ARB in different environments. Furthermore, the oxidative stress response of ARB was significantly lower than that of ASB on a copper substrate, and the intracellular reactive oxygen species (ROS) level in ARB was only 78.7% of that of ASB. Gene expression patterns revealed that ARB biofilm formation on the copper substrate was mainly caused by the c-di-GMP-activated signaling pathway rather than the SOS stress system activated by ROS. These findings have implications for the choice of copper products in water supply systems.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 4","pages":"1546–1556 1546–1556"},"PeriodicalIF":4.8,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814438","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}

This study developed a tailored molecular sieve material, i.e., mesoporous Y-zeolite (M-Y zeolite), through hydrothermal synthesis for tetracycline (TC) removal from simulated and real water matrices. The average pore size of M-Y zeolite was 3.16 nm, more than 1.7 times the second-widest dimension of the targeted TC molecule (0.81 nm), allowing for effective adsorption. With a specific surface area of 516 m2 g–1, M-Y zeolite achieved a maximum adsorption capacity of 88 mg g–1. The pseudo-second-order and Freundlich models indicated that adsorption occurred on a multilayer heterogeneous surface through chemisorption. The intraparticle diffusion model indicated that the adsorption process was governed by both liquid film diffusion and intraparticle diffusion. Mechanistic studies identified pore filling, complexation, and electrostatic interactions as the main adsorption mechanisms. After four regeneration cycles, the M-Y zeolite retained 66% of its initial adsorption capacity. In real water tests, removal efficiency slightly declined (4–14%) at 10 mg L–1 TC due to competing ions and organic matter but remained >99% at 0.1 and 1 mg L–1 TC. These findings offer a promising mesoporous material for antibiotic removal, marking a significant advancement in water treatment.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1373–1383 1373–1383"},"PeriodicalIF":4.8,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609112","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}

However, their inherent hydrophobicity and low surface area limit the Hg2+ uptake. This study introduces novel hydrophilic porous adsorbents, developed by carbonizing (with or without potassium hydroxide (KOH)) inverse vulcanized copolymers to enhance mercury removal efficiency from wastewater. Two copolymers were synthesized: one from sulfur (S) and methacrylic acid (MA) (Copoly(SMA)), and the other from S and vinyl benzyl chloride (VBC), later functionalized with N-methyl-d-glucamine (NMDG). Methacrylic acid and NMDG functionalization were introduced to enhance copolymer hydrophilicity with −OH groups. Carbonization in the presence of KOH significantly boosted surface area and pore formation, yielding a maximum surface area of 175.5 m2/g of the NMDG-functionalized carbonized copolymer (Copoly(SVBC)@NMDG_KOH_C)─68, 3.5, and 1.32 times greater than the uncarbonized, carbonized Copoly(SMA)_C, and KOH-aided carbonized Copoly(SMA)_KOH_C copolymers, respectively. Adsorption tests revealed a maximum mercury adsorption capacity of 572.4 mg/g (Langmuir) for Copoly(SVBC)@NMDG_KOH_C, underscoring its potential as a mercury adsorbent. Isotherm and kinetic analyses reveal that mercury uptake follows the Langmuir model, demonstrating monolayer adsorption, and fits well with pseudo-second-order kinetics, indicating chemisorption as the primary mechanism. Furthermore, economic analysis showed that mercury removal with this adsorbent is cost-effective at just $9.95 per gram of Hg removed from wastewater.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1499–1509 1499–1509"},"PeriodicalIF":4.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609047","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}

This study aims to improve the hydraulic efficiency of Denil fishways by investigating the influence of different shapes of baffles (i.e., triangular, semicircular, and rectangular) on hydrodynamic parameters. Using computational fluid dynamics (CFD) simulations, we evaluated the performance of the modified guardrail configurations. The numerical model was validated by comparing computed flow depth (hu) and discharge coefficient (Cd) with those measured experimentally from the literature. The study showed that the modified baffles significantly affected the flow characteristics. The rectangular baffles reduced the flow depth by up to 25.8% and increased the Cd value by 75.7% compared to the standard triangular baffles. In addition, the rectangular baffle design was characterized by the creation of a low-velocity zone, which is crucial for fish passage, especially for smaller species. These results suggest that modified guardrail shapes can improve the hydraulic efficiency of Denil fishways, providing a potential solution to improve fish migration through fragmented river systems.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1295–1309 1295–1309"},"PeriodicalIF":4.8,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609042","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}

The existing research mainly focuses on one aspect of vegetation resistance or recovery, lacking a comprehensive quantitative evaluation method of vegetation ecological resilience. The quantitative methodology for assessing vegetation resistance and recovery from drought, utilizing gross primary productivity (GPP), is refined in this paper. These two indicators of vegetation resistance and recovery are combined to develop an evaluation strategy for assessing vegetation ecological resilience under drought conditions. Taking the Yellow River Basin as an example, the results showed that the vegetation ecological resilience of the Yellow River Basin under drought stress showed a downward trend from 1982 to 2018. Spatially, the distribution of low resilience in arid and semiarid areas in the north and high resilience in river source and downstream areas is presented. The ecological resilience of woodland is the highest, that of grassland is the lowest. It helps to gain a deeper understanding of the drought adaptation mechanism of vegetation in the Yellow River Basin under the background of climate change, and provides support for the sustainable development of the vegetation ecosystem under environmental change.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1229–1239 1229–1239"},"PeriodicalIF":4.8,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609046","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}
