Wastewater-based epidemiology (WBE) can provide critical early warnings to aid public health, which can be particularly beneficial in rural communities with limited access to health care. Spikes of SARS-CoV-2 RNA concentration in wastewater have been used to represent infections in a community, but wastewater holds a wealth of information that has not been explored yet. The objectives of this research

Leak detection is crucial for the healthy operation of water pipelines and efficient water resource conservation. However, traditional acoustic signal-based leak detection methods for water pipelines often capture only shallow or incomplete features, resulting in suboptimal accuracy in identifying leaks of varying severity. To address this limitation, we propose a water pipeline leak detection method

Chlorine is the principal microbial disinfectant used for water treatment. However, chlorine-resistant bacteria such as Mycobacterium spp., can survive chlorine treatment and even grow in the presence of chlorine, posing potential public health risks. In this study, we isolated a Mycobacterium sp. strain from treated effluent and investigated its chlorine resistance and recovery using transcriptomic

Ultraviolet radiation (UV) is the most energetic waveband of incident solar radiation and has wide‐ranging effects in the aquatic environment. Our analysis of an 18‐year record of underwater irradiance and related limnological variables in sub‐alpine, ultra‐oligotrophic Lake Tahoe revealed orders of magnitude changes in UV transparency associated with interannual climate perturbations. The large‐scale

Accompanied by high energy consumption and the difficulty in maintaining process stability, the treatment of pesticide wastewater in cold climates remain a significant challenge due to its low biodegradability and complex composition. Therefore, this study developed a hybrid anaerobic membrane bioreactor (HAnMBR) that incorporates ferromagnetic biochar and a partitioned upflow anaerobic sludge blanket

Microbiota within interconnected river-lake systems define cycles of carbon and nutrients, yet the mechanisms underlying the assembly of microbial communities during their transition from tributaries to lake remains to be deciphered. This study examined the communities of protists, fungi and bacteria in sediments of Qinghai Lake – a saline lake on the Tibetan Plateau, China – and its connected upstream

Non-point source (NPS) pollution in mosaic agricultural micro-watersheds poses significant challenges for water quality management due to dynamic interactions between fragmented land uses and rainfall variability. Traditional CSA identification methods, which rely on static parameters for pollutant load estimation and simplified hydrological distance metrics, fail to capture spatiotemporal shifts in

There's growing interest in using membrane technology to treat oily wastewater in industries. Nevertheless, membrane fouling is still a major challenge for removing oil particles from the wastewater. As reducing the membrane fouling requires material and surface science insights, in this work, a nanocomposite membrane was investigated for oily wastewater treatment using synthesized silver nanoparticles

The sustainable development of modern cities requires seeking rational water resources allocation strategies to alleviate supply–demand conflicts and improve the adverse development trend of water resources carrying capacity (WRCC). In this study, a conceptual framework of water resources "Endowment-Utilization-Development-Risk-Green (EUDRG)" is constructed to evaluate WRCC, and the coupling coordination

The potential long-term deleterious effects of parabens on ecosystems, particularly as endocrine disruptors, have been a source of concern due to their persistent presence in natural waters. This study evaluated the catalytic performance of Fe3O4-enhanced granular activated carbon (Fe3O4-GAC) in the catalytic ozonation of methyl-paraben (MP) and ethyl-paraben (EP). Characterization confirmed that Fe3O4

This paper uses a non-convex metafrontier approach to study the temporal evolution and the productivity change in the water usage efficiency of 91 countries during the period 2015–2020. A circular three-stage Network Data Envelopment Analysis (NDEA) production process is considered. The non-radial Directional Distance Function (DDF) is used to compute the system efficiency as well as that of the three

Monitoring and assessing the water budget is crucial, especially in the context of climate change and increasing occurrences of extreme weather events. The water budget is influenced by precipitation, evapotranspiration, and surface runoff, which are shaped by meteorological conditions. Additionally, terrain topography and land cover structure play a significant role, although they are often overlooked

The role of soil moisture (SM) in determining natural hazards such as flash floods, debris flows, and landslides in mountainous areas is critical. However, the operational capacity to monitor SM in real-time is constrained by the temporal resolution of low-Earth orbit satellite platforms. To address this, we developed a machine learning (ML) framework that fills Soil Moisture Active and Passive (SMAP)

In the ocean, the depleted signal of riverine black carbon (BC) has challenged our knowledge of the BC origin, largely due to a poor understanding of the BC fate in the river-to-coast continuum. Here, the time-series observations of particulate soot BC (PBC), bulk POC, δ13C, and 234Th were conducted in the river-dominated Xiamen Bay to examine the export of PBC to the Taiwan Strait. δ13CPBC (?20.5?‰

This study presents a methodology for estimating the saturation index (SI) of halite, gypsum, anhydrite, and calcite, as well as the partial pressure of CO2 (logPCO2), using easily measurable water parameters: electrical conductivity, temperature, and pH. Our approach eliminates the need for extensive chemical analyses, allowing an efficient on-site application. PHREEQC was used to generate water composition

Due in part to the lack of continuous-in-space-and-time flow and sediment transport data, the river morphodynamic processes during large floods are not fully understood. This study developed a two-dimensional (2-D) morphodynamic model to study the morphodynamic process of a gravel-bed river during a flood event with a return period of 80?years in Calgary, Canada. The model was calibrated against post-flood

As one of the major components of the water cycle, accurate estimation of evapotranspiration (ET) at regional scales is challenging, especially over drylands due to the strong soil water constraint. Recently developed remote sensing-based ET products, especially the widely used Priestley Taylor–Jet Propulsion Laboratory (PT-JPL) product (e.g., ECO3ETPTJPL), tend to overestimate ET in the US southwest

In the realms of agricultural water resource management, water resources planning, and drought monitoring, the accurate estimation of reference crop evapotranspiration (ETo) is of the utmost importance. Despite the Penman-Monteith equation, recommended by the FAO, offering highly precise estimates of ETo, its dependence on high-quality meteorological data, including solar radiation, air temperature

As water distribution networks (WDNs) become increasingly connected with digital infrastructures, they face greater exposure to cyberattacks that threaten their operational integrity. Stealthy False Data Injection Attacks (SFDIAs) are particularly concerning, as they manipulate sensor data to compromise system operations while avoiding detection. While existing studies have focused on either detection

Hydrological structural connectivity exerts a critical influence on the transport, distribution, and deposition of runoff and sediment within watersheds. However, its impacts on runoff-sediment relationships remain insufficiently understood. In this study, two typical watersheds Laoshanchong (LSC) and Longyan (LY) in southern China with different hydrological structural connectivity were employed.

Identification of rainfall thresholds remains a key problem in debris flow forecasting. Usually, a rainfall threshold is derived through linking rainfall and debris flow occurrence; however, the results are largely inaccurate in many cases. In this work, artificial intelligence methods were employed to select the optimal parameters for forecasting, and to evaluate the uncertainties of different parameter

Montane snowpack in the Sierra Nevada provides critical water resources for ecological functions and downstream communities. Forest removal allows us to manage the snowpack in montane forests and mitigate the effect of climate on water resources. Little is known about the mid- to long-term effects that changing snowpack following forest disturbance has on tree re-growth, and how tree re-growth might

Subterranean estuaries (i.e., seawater‐fresh groundwater mixing zones at coastal aquifers) are highly reactive boundaries between continental groundwater and coastal surface seawater. Because particulate organic matter is retained in shallow sediments, internal microbial transformations rely on dissolved organic matter (DOM) supply and bioavailability. Here, we investigated DOM carbon content and optical

Approximately one-third of the world’s national borders are delineated by rivers. The movement of these rivers can threaten land use and the territorial security of riparian nations. However, there is currently a paucity of quantitative assessments by scholars regarding the territorial security impacts induced by changes in International Boundary Rivers (IBRs). In this study, we examine the longest

The effect of global climate warming on the Qinghai-Tibetan Plateau (QTP) has resulted in degradation of permafrost. This has in turn impacted water flow in the rivers and the formation of numerous lakes due to the erosion and migration of river channels. The connectivity between the rivers, groundwater, and these lakes was not investigated due to the complex landscape conditions. To overcome this
