Several researchers nationally and internationally contributed to developing the technical solutions, designing the national/sub-national policies and guidance for efficient management. 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}

Over two billion people live in countries that are experiencing water scarcity, while double that number live in countries that experience water scarcity at least one month a year [5]. Lack of clean water can lead to severe impacts both in terms of health and well-being and reduced economic growth [4,5]. The challenges associated with water scarcity are only projected to be exacerbated by various complex factors causing unsustainable management and withdrawals of key water sources in the decades ahead. Water scarcity can be addressed through two approaches, defined as improved water efficiency practices and the introduction of different water streams that could replace traditionally sourced potable water. While regulations have been implemented to make water use practices more efficient, water use efficiency alone has not been enough to overcome the increasing water demand. With recent advancements and technologies in treatment and monitoring water reuse has been thrust back into the spotlight as a viable option to help create a more sustainable water supply. Globally water reuse is in varying stages of implementation based on geographic, cultural, legislative, and economic factors. Levels of use range from advanced, with some countries receiving a majority of their water from recycled sources, to non-existent. This paper will focus on the legislative framework that exists in the United States today for municipal water reuse.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"20 ","pages":"Article 100154"},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138447928","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}

Worldwide, around 200 million people are dependent on drinking water<span> resources that contain elevated levels of fluoride that exceeds WHO’s drinking water threshold limit of 1.5 mg/L. According to the Ministry of Drinking Water and Sanitation of India, about 11.7 million people, mostly in the Rajasthan state, are exposed to high fluoride risk. It is important to understand the soil–water interaction mechanisms to properly assess the fluoride contamination that are primrily due to geogenic origins prevalent in the region. In this study, batch desorption experiments were performed with soils obtained from varied depths at two sites in Rajasthan that has high fluoride levels in groundwater. The fluoride release kinetics followed a pseudo first-order kinetic model. The results of the batch experiments indicate higher release of fluoride from lower soil layers when compared to the upper layers. Further, the release of fluoride was dependent on pH wherein higher release was noticed under basic pH. Since the natural pH of the soils from this region is ca. pH 8 it is expected to play a vital role in the continued release of fluoride to the groundwater system. Furthermore, a simplified geochemical model, incorporating a general composite approach, has been used to simulate the experimental results that include dissolved Al and Al-F surface complexes. The model was able to capture the observed experimental results for various soils within a reasonable RMSE of 11.74%. The results of this study not only further the current understanding of the fate and transport mechanisms of fluoride in the contaminated subsurface but also would aid in designing remedial strategies to ensure future water security in this region.</span></p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"19 ","pages":"Article 100140"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49712366","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}

To understand the geochemical controls of arsenic mobilization in the region, batch sorption experiments were performed using soil obtained from arsenic contaminated district of Punjab. This study presents a novel approach by employing surface complexation models (SCMs) to investigate arsenic adsorption onto natural soils in the Punjab region, which has not been explored in previous literature. Furthermore, a comparison between Fe-based models, assuming ferrihydrite binding, and general composite (GC) approach, assuming adsorption on soil component surfaces, has not been conducted before, adding to the originality of this research. The adsorption kinetic experiment indicates about 70% adsorption of As(V) in about 4 h. The results of batch isotherm experiment shows that As(V) adsorption saturation onto the soil is reached at an aqueous concentration of about 0.89 mgL<sup>−1</sup>. The results of the pH edges study shows a maximum As(V) adsorption of 93.88% at a pH of 4. The Langmuir’s isotherm was the best fitted because the value of linear regression coefficient (R<sup>2</sup> = 0.997) which verifies the monolayer adsorption of As(V). It was observed that the pseudo first order model best fitted for explaining the kinetic of As(V) adsorption onto the soil because it showed higher value of linear regression coefficient (R<sup>2</sup> = 0.995). Further, three different diffused layer models under varied assumptions were used to capture the batch experimental results. The surface complexation model with general-composite (GC) approach fairly predicted the experimental results when compared to Fe-oxide based models. The GC model was able to capture the observed experimental results for adsorption isotherm and pH edges for the soil within reasonable RMSE of 6.22 % and 7.97 %, respectively.</p></div>","PeriodicalId":37308,"journal":{"name":"Water Security","volume":"19 ","pages":"Article 100139"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44184502","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}
