This study investigated public perceptions of nontraditional water reuse, particularly oil and gas–oil and gas produced water reuse, in New Mexico, using valid responses from 657 statewide survey participants. Results showed substantial public support (up to 68.5%) for reusing various nontraditional water sources, including produced water. Awareness gaps were identified, particularly among younger individuals, those with lower educational attainment, and residents in less drought severe counties. Statistical analysis revealed significantly greater support for nontraditional water reuse (&gt;74%) in severely drought-stricken counties with an average drought severity and coverage index (DSCI) &gt;300 compared to those in milder drought conditions (&gt;62.1%, average DSCI &lt; 200), highlighting the influence of direct experience with water scarcity on public attitudes. Increased public awareness correlated with stronger support for reuse initiatives, highlighting the need for targeted education and outreach efforts. Concerns about the safety of produced water reuse emphasized the importance of transparent communication on treatment processes, monitoring, and regulatory oversight to ensure safe reuse. These findings offer valuable guidance for policymakers to develop effective water reuse strategies and bolster public support for sustainable water management practices.</p>","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 2","pages":"761–771 761–771"},"PeriodicalIF":4.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402396","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}

STXs (STX), produced by these harmful algal blooms, are a class of potent neurotoxic alkaloids that exhibit resistance to conventional water treatment processes like oxidation. Adsorption using carbon-based materials is recommended for STX removal, but current adsorbents have limited efficacy. Here, we demonstrate that mesoporous graphene nanoplatelets (GnPs) are a superior adsorbent for STX, outperforming granular activated carbon (GAC) and other benchmarks in both kinetics and capacity. GnPs achieved a 93.5-fold higher adsorption capacity and over 6-fold faster kinetics compared to GAC. The exceptional performance of GnPs is attributed to their high surface area, favorable surface chemistry, and optimized pore structure that facilitate rapid and extensive STX adsorption through π–π interactions, electrostatic attraction, and intraparticle diffusion. Mechanistic studies revealed a critical role of solution conditions, with higher pH and lower ionic strength enhancing STX removal by promoting electrostatic interactions. GnPs also demonstrated excellent performance in simulated field water, maintaining &gt;90% removal within 1 h even in the presence of competitive organics. This study highlights the immense potential of GnPs as an advanced adsorbent for mitigating the rising threat of STX contamination in drinking water.</p><p >Novel graphene-based adsorbents demonstrate exceptional removal of freshwater saxitoxins, offering promising solutions for emerging water contaminant treatment.</p>","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 2","pages":"881–890 881–890"},"PeriodicalIF":4.8,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c00932","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402487","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}

Here, a design strategy to improve the water production performance of the SMD system through the synergistic effects of multifaceted structural optimizations is clarified. By constructing a thermal insulation chamber at the first stage to reduce convective heat loss and combining the evaporative cooling effect at the final stage to enhance thermal dissipation capability, the overall temperature gradient as the evaporation driving force of the SMD system is enhanced. Simultaneously, the vapor diffusion resistance is reduced by utilizing 3D printing technology to optimize the interstage air gap. An excellent water collection rate (WCR) of 2.71 kg m<sup>–2</sup> h<sup>–1</sup> is obtained through a 6-stage SMD device under one sun. Furthermore, the 6-stage device exhibits good practical application potential by achieving a substantial WCR of 12.28 kg m<sup>–2</sup> day<sup>–1</sup> in an actual outdoor deployment.
