These metrics typically rely on the relative abundance of “indicator taxa,” their overall sensitivity to impairment, and their environmental optimum along a pollution gradient. In South America, microalgal assemblages have only recently been used to monitor and evaluate the water quality in continental waters. This study aims to design and validate a new diatom metric, the Ecuador Diatom Index (EDI), to enhance water quality assessment in Ecuadorian river basins. The EDI reflects the overall limnological condition of a river, measured through various abiotic parameters integrated into the water quality index. Biological sampling was conducted at 111 stations across the Ecuadorian river basins. Notable differences were observed in floristics and autoecological parameters compared to other diatom-based methods. Statistical analyses revealed that beyond optimum and tolerance, incorporating specific frequency of occurrence and goodness-of-fit to a Gaussian response curve improves the reliability of this metric, surpassing the results of the commonly used specific pollution sensitivity index.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"4 9","pages":"3816–3823 3816–3823"},"PeriodicalIF":4.8,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228411","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 generation of MCA at the treatment plant requires tight control over both pH and the ratio of free chlorine (FC) to ammonia to avoid forming undesirable byproducts such as dichloramine (DCA) and trichloramine (TCA), which can impart odor and toxicity to the water. Therefore, continuous monitoring of MCA is essential to ensuring drinking water quality. Currently, standard colorimetric methods to measure MCA rely on the use of reagents and are unsuitable for online monitoring. In addition, other oxidants can interfere with MCA measurement. Here, we present a solid-state, reagent-free MCA sensing method using an array of few-layer graphene (FLG) chemiresistors. The array consists of exfoliated FLG chemiresistors functionalized with specific redox-active molecules that have differential responses to MCA, FC, and DCA over a range of concentrations. Chemometric methods were employed to separate the analytes’ responses and to generate multivariate calibration for quantification. A minimum of three sensors are required in the array to maintain full functionality. The array has been demonstrated to quantify MCA in buffered and tap water as a low-cost, reagent-free approach to continuous monitoring.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"4 9","pages":"4041–4051 4041–4051"},"PeriodicalIF":4.8,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228353","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}

Regrettably, up to 80% of treated industrial effluent is discharged directly into water bodies, posing severe environmental contamination risks. This underscores the critical necessity for sustainable wastewater management. Among the industries that consume large amounts of water is the automotive. Automotive wastewater, primarily from emulsion and paint processes, contains toxic substances such as paints, metals, and organic compounds. Additionally, dyestuffs and paints contribute to environmental challenges due to their toxicity and slow degradation. This review explores different wastewater treatment approaches, including physicochemical, biological, and membrane technologies, to tackle the complexity of automotive wastewater. Physico-chemical methods effectively remove pollutants but generate sludge. Biological treatments face challenges related to heavy metals and nonbiodegradable compounds. Membrane separation, particularly forward osmosis, shows potential as an energy-efficient solution. The review addresses challenges in automotive wastewater treatment, like sludge management and heavy metal inhibition. Advanced approaches, such as enzyme-based treatments and natural materials like banana peels, and zeolites natural and synthetic are discussed for their potential to enhance efficiency. This article offers insights into the current state of automotive wastewater treatment, emphasizing the need for green solutions to protect public health and the environment.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"4 9","pages":"3663–3680 3663–3680"},"PeriodicalIF":4.8,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228410","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}

In the United States, lawsuits between states can be heard only by the Supreme Court of the United States (SCOTUS). These lawsuits are expensive and lengthy, often requiring highly specialized technical expertise. In the MS vs TN case, the Court unanimously held that an interstate aquifer is subject to equitable apportionment. Although this appears to be a sound resolution, a careful examination of the SCOTUS hearing transcript revealed that the Justices had several egregious misconceptions about the groundwater system. These misconceptions arose in part due to the failure of technical experts to communicate groundwater concepts in understandable terms and in part due to the Justices’ lack of expertise in groundwater science. To address these issues, we first explore methods for improving scientific communication in courtrooms. Second, we propose ideas for reforming the legal system and provide compelling arguments for using the lower courts to hear such cases.

The results showed that contaminated groundwater had higher humification degree, chemical diversity, and unsaturation of DOM compared to uncontaminated groundwater. Five fractions were identified in landfill leachate, with fulvic-like acid and building blocks of humic substance fractions (0.45–2.5 kDa) being poorly retained by soil upon leakage. In contrast, high-molecular humic-like acid and biopolymer fractions (>2.5 kDa) as well as low-molecular organic fractions (<0.45 kDa) were readily adsorbed in soil, leading to the appearance and intensification of characteristic fluorophores at excitation/emission wavelengths of 250, 310, 365 nm/460 nm in contaminated groundwater. The characteristic fluorophore representative molecules comprised highly unsaturated structures with low- and high-oxygen content (79.6%) with high oxidizability, aromaticity, and unsaturation. To the best of our knowledge, this was the first report of the medium-molecular-weight organics in leachate preferentially entering groundwater rather than the low-molecular weight organics.

This study originates from an in-depth investigation into how critical ions and natural organic matter in freshwater influence disinfection. The results show that the higher concentrations of chlorides (>400 mg/L) and natural organic matter (>1.5 mg/L) adversely affected the composite disinfection ability as expected. Intriguingly, the nanocomposite shows enhanced disinfection in the presence of bicarbonate alkalinity and hardness. A detailed investigation shows that bicarbonate plays a vital role in enhancing disinfection. The studies reveal a synergy between bicarbonate and Ag+ released from a nanocomposite film. The bicarbonates disturb the transmembrane potential gradient (ΔpH), weaken the proton motive force of (Escherichia coli), and enable an increased penetration of Ag+ into the cell, resulting in enhanced production of reactive oxygen species and cell damage. This synergetic effect could help reduce the costs and concentration of Ag+ required for disinfection and their associated risks. The cytotoxic studies against human cell lines (HaCaT) confirm that AgNC-treated water is safe for consumption.

When compared to regulatory limits, the observed atrazine concentrations in Mae Sa were generally below environmental thresholds of concern. However, greater risk may occur in other tributary systems feeding the Ping River, where some concentrations exceeding 2000 ng/L were observed, although they were not sustained for extended periods of time. Additionally, nontargeted screening identified 16 other agrochemicals with known potential environmental risks or associated toxicity. Despite the minor risk posed by atrazine alone, the research highlights the intricate interplay of agricultural practices, diverse pesticide application, and hydroclimatic factors in influencing pesticide dynamics. In the broader context, this study underscores the challenge of estimating risks arising from pesticide mixtures while using a combination of targeted analysis, nontargeted screening, in silico prediction models, and in vitro bioassays.

Statewide mass estimations revealed that North Carolina and New York contribute to the major PFAS mass released from cosmetics, while Georgia and California contribute to the major PFAS mass released from carpets. The average per capita PFAS footprint from carpets and cosmetics is about 103 mg/year. Upon disposal, over 60% of the mass eventually ends up in landfills. The accumulation of PFAS stocks in landfills, primarily from carpets and to some extent from cosmetics, highlights the critical need to cease the production and use of PFAS in consumer products. Coastal counties are particularly vulnerable due to higher population and therefore higher consumption of these PFAS-tainted consumer products. Additionally, counties with densely populated areas and with preexisting contamination sources would face increased vulnerability to PFAS contamination released from various consumer products.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"4 9","pages":"3882–3892 3882–3892"},"PeriodicalIF":4.8,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228368","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 system was evaluated in terms of nitrogen transformation, organic removal efficiency, and pathogen levels. Although soluble organic removal efficiencies (sCOD) were high (>80%) in all bioreactors, nitrification was limited due to high organic loading (350–800 mg sCOD L–1), relatively short retention time (24 h), and low dissolved oxygen levels (<3.5 mg O2 L–1). Grow beds showed significant nitrification, indicating the importance of upstream organic removal. CO2 supplementation (0.5% v/v) in bioreactors did not promote nitrification in the bioreactors but was beneficial for nitrification in grow beds due to pH-modulating effects.
