This paper examines how the pandemic caused a water security crisis for many communities, and in so doing, our analysis contributes to current debates on water system resilience and continued challenges of water affordability in the United States. Water utilities faced major shifts in industrial and domestic water demand, financial burdens of increased non-payments, and operational challenges due to a reduced workforce and supply chain bottlenecks. Areas of concern include customer protection, financial security, public communication, new technology adoption, and trust. Evidence indicates that the pandemic water crisis spurred institutional and technological innovation to increase resilience for the next shock while overall financial challenges in the post-pandemic years remain. The pandemic water crisis also revealed a stark tradeoff between household water security and water utility security, indicating that without systemic changes to policy and practice related to water affordability, the most vulnerable in the United States will continue to suffer in future crises.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"20 ","pages":"Article 100144"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138467818","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 article addresses the major system typologies that can be implemented and the obstacles that are preventing many such communities from receiving funding and implementing systems. While preference for disadvantaged communities is incorporated into federal funding opportunities and many stakeholders prioritize the neediest communities, the embedded perverse incentives and asymmetric information present substantive obstacles to these goals. Small communities and other stakeholders have often found their efforts frustrated by a system that was designed for larger municipalities (or higher-income communities) with greater internal capacity and which is highly dependent on engineering firms, most of which prefer large projects with conventional technological approaches. Novel approaches that show promise in enabling sustainable wastewater management in low-population density, underserved communities are those that leverage existing infrastructure (e.g., gravity sewer, high-speed internet) with recent innovations in infrastructure and management (e.g., liquid-only sewer, centralized management of decentralized infrastructure) and/or incorporate creative approaches to funding and technical assistance.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"20 ","pages":"Article 100152"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2468312423000202/pdfft?md5=22a7dfff40773ec309554f38f5ceaba4&pid=1-s2.0-S2468312423000202-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138489630","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}

This leads to many people consuming contaminated water, which is associated with several health risks. It is thus, important to reduce exposure to water-borne pathogens and toxic chemicals through effective water treatment. In this regard, point of use (POU) water treatment techniques can ensure quality drinking water, especially where water treatment systems are compromised, or where centralized water treatment systems are non-existent. An affordable POU water treatment option for LICs is the use of ceramic filtration. The goal of this review is to evaluate the application of ceramic filtration as a POU technique in LICs. Specifically, the review aims to: (1) review previous studies on low-cost ceramic filters used in LICs, (2) evaluate the pollutant removal performance and limitations of the filters, and (3) provide future research directions. The major findings are: (1) low-cost ceramic filters are effective POU devices, (2) modification of ceramic filters improves performance, and (3) more robust multicomponent removal devices can be made from combining ceramic filtration and other techniques. Overall, this information is important for use by local authorities in LICs in formulating policies and regulations that conduce the provision of safe drinking water to disadvantaged communities.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"20 ","pages":"Article 100145"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2468312423000135/pdfft?md5=ddfa0e718f9f20b1151a9bd2ea354bec&pid=1-s2.0-S2468312423000135-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138467819","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}

Many of these researchers include female researchers who are working on water research aspects across regions. The database review of the lead female researchers gives an opportunity for insights into the trending research in the water sector. In this paper, an attempt has been made to do a bibliometric analysis of the Scopus database (2001–2021) for analyzing the research related to water quality, water management, hydrology, and water research. The 21 years Scopus database was downloaded including research papers, books, and conference proceedings, which were then examined for the gender of the first author. The gender analysis of the first author was done by searching them on ResearchGate, Google Scholar, LinkedIn, and other social networks. Further, the bibliometric analysis of female first-authored papers was done in the R-Biblioshiny for results like research trends, most relevant authors, most relevant sources, and most global cited documents. There were about 2975 documents including research papers, books, and conference proceedings in water management and water research. The bibliometric analysis visualizes various ways of literature review in the water sector. The gender involvement analysis will help to formulate the research agenda and topics by considering women’s vital role in water management in every sector.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"20 ","pages":"Article 100155"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138489629","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}
