However, earlier reviews on the subject have generally lacked the inclusion of the latest publications, and some of the findings reported across different studies remain inconsistent. The present review updates recent advancements in NDMA in water, addressing topics ranging from the origins of NDMA precursors and its formation mechanisms to removal technologies, while also providing an objective assessment of conflicting results in the literature. Insights and strategies for improving NDMA control are discussed, including source reduction, process optimization, and end-of-pipe removal. For practical applications, strategies for NDMA control could be selected based on the cost-effectiveness analysis. It is recommended to use a multiple-barrier system when funds are sufficient. Besides, this review provides a forward-thinking perspective for future NDMA research, suggesting establishing a global NDMA database, based on a combination of experimental tests (e.g., bench tests) and in silico approaches (e.g., quantum chemical computation and machine learning).</p>","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 4","pages":"1514–1529 1514–1529"},"PeriodicalIF":4.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814563","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}

Understanding Ni behavior within environmental contexts requires knowledge of its binding to environmentally relevant minerals such as birnessite during and after precipitation. Here, we compare Ni binding at initial (48-h) and aged (14-day) time frames onto fungal (via <i>Stagonospora</i> sp. SRC1lsM3a) and abiotic birnessite, as fungi are important Mn oxidizers in contaminated sites, with two timing-of-addition scenarios: reacting preformed birnessite and coprecipitation. X-ray absorption spectra were collected to track the mineral structures and Ni binding modes. Aging abiotic and fungal birnessites reacted with Ni increase the hexagonal sheet symmetry and average Mn oxidation state (AMOS), while coprecipitation yields similar initial (and stable) structures. Aging also shifts Ni from biomass- and edge-bound sites in fungal and abiotic systems, respectively, to binding the above vacancies and incorporating into the mineral structure. Incorporated Ni is positively correlated with AMOS and Mn(IV) content, with both fungal- and abiotic-aged samples achieving 2.3 mol % (mol Ni:mol Mn) incorporation, albeit with different timing-of-addition scenarios.

Yet, simple zero-order kinetics can often describe the reduction rates at the aquifer scale. We tackle this discrepancy by deriving the steady-state concentrations of subsurface biomass, electron acceptors, and electron donors for a reactive system. As an example, we model denitrification coupled with the oxidation of dissolved organic carbon stemming from solid-phase natural organic matter. Our closed-form solution demonstrates that the microbially mediated hydrolysis step, releasing the electron donor from the matrix, limits the overall reaction. Neither the steady-state concentration of biomass nor the reduction rate of the electron acceptor depends on the available electron-acceptor concentration. These findings are confirmed by numerical experiments with a more complete description of the system. Our theoretical derivations provide a mechanistic explanation for apparent zero-order reduction rates observed in field and experimental settings at steady state. They apply to various settings in which dissolved electron acceptors react with electron donors released from the matrix. To better understand and quantify the reduction rates of electron acceptors at field sites, we propose investigating the processes and rates controlling the microbial access to solid-phase electron donors.</p><p >We mechanistically explain how complex dynamics of microbially catalyzed electron-acceptor reduction in groundwater ecosystems can result in apparent zero-order kinetics.</p>","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 4","pages":"1889–1896 1889–1896"},"PeriodicalIF":4.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c01232","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814528","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}

Thus, many water utilities are turning to or considering water recycling to augment existing supplies. It is incumbent on a utility to demonstrate that augmenting its water supply with recycled water does not create undue excess risk compared to existing sources that are considered protective of public health. This research quantified the chemical risks associated with using recycled water as a source of water supply. Linear cancer slope factors and threshold dose values were used with chemical concentrations measured at an advanced water recycling pilot in the southern UK to quantify chemical risk profiles of six waters: two existing drinking water source waters, a secondary treated wastewater effluent serving as the influent to the advanced water treatment pilot, and after each treatment step in the pilot (ultrafiltration, reverse osmosis, and ultraviolet advanced oxidation). This study builds on previous work by considering risks throughout the advanced water recycling treatment train via Monte Carlo simulation and evaluating several approaches to handling censored data sets; the analysis leveraged data from an extensive sampling campaign including 37 cancer risk chemicals and 289 threshold-based risk chemicals. Overall, conclusions around relative risk were relatively insensitive to the approach used for handling censored data, while using a stochastic method provided improved insights into the variability of risk. Cancer and noncancer risk profiles of water treated through the advanced treatment train were comparable or better than existing water supply works source waters.
