ClearDrinking water potability prediction using machine learning approaches: a case study of Indian rivers
Researchers applied machine learning techniques to predict drinking water quality in Indian rivers based on key parameters like pH, dissolved oxygen, and bacterial counts. Their models achieved high accuracy in classifying water as potable or non-potable. The study demonstrates how data-driven approaches could help developing countries monitor water safety more efficiently, especially in regions where traditional testing infrastructure is limited.

[Spatial and Temporal Variation Characterization and Variability of Microplastics in Water-borne River and Reservoir].
A study comparing microplastic levels in a river and a reservoir used as drinking water sources in Guangdong, China found meaningful differences in contamination patterns across seasons and locations. The findings underscore that drinking water source protection strategies need to account for microplastic pollution, as these particles can enter the water supply before treatment.
From the Mountain to the Valley: Drivers of Groundwater Prokaryotic Communities along an Alpine River Corridor
Researchers sampled river water and groundwater from 59 sites along a 300 km transect of the Mur River valley in Austria and Slovenia, finding that dispersal limitation drives microbial community assembly at high altitudes while homogeneous selection dominates in lowland aquifers, with land use being a key determinant of groundwater microbiome composition throughout.
Sources and Consequences of Groundwater Contamination
Researchers reviewed sources and health consequences of groundwater contamination across India, China, Pakistan, Turkey, Ethiopia, and Nigeria, summarizing both geogenic pollutants (naturally occurring) and anthropogenic contaminants while identifying key gaps in remediation technology and monitoring capacity.
Fate of Microplastics in Deep Gravel Riverbeds: Evidence for Direct Transfer from River Water to Groundwater
Researchers tracked microplastic particles vertically through gravel riverbeds using depth-profile sampling, finding that MPs move directly from river water into subsurface gravel sediments and onward toward groundwater, documenting a pathway for plastic particles to enter drinking water aquifers.
Microplastics transport during Managed Aquifer Recharge – A potential cause of groundwater contamination?
Researchers measured microplastics at multiple stages of a major managed aquifer recharge system in Switzerland and found that plastic particles from the Rhine River can penetrate through the treatment process into pumped groundwater, raising concerns about drinking water quality.
Many oil wells, one evil: comprehensive assessment of toxic metals concentration, seasonal variation and human health risk in drinking water quality in areas surrounding crude oil exploration facilities in rivers state, Nigeria
Researchers assessed toxic metal concentrations in drinking water near crude oil exploration facilities in Nigeria, finding seasonal variations and levels exceeding safety thresholds that pose serious health risks to surrounding communities.
Microplastics in Drinking Water: Assessing Occurrence and Potential Risks
This review paper examines how widespread microplastics are in drinking water — from rivers and lakes to groundwater — and what health risks this contamination may pose. The authors call for urgent research into how microplastics move through water treatment systems and ultimately reach taps, emphasizing that current sampling and analytical methods are inconsistent, making it hard to compare studies or set safety thresholds. For people drinking tap or bottled water daily, understanding and regulating this exposure pathway is a pressing public health priority.
US drinking water quality: exposure risk profiles for seven legacy and emerging contaminants
Researchers profiled the risk exposure patterns for seven contaminants found in US drinking water, including both legacy pollutants and emerging threats, finding that contamination is widespread even in developed water systems. Understanding which contaminants affect which communities is essential for targeting public health protections and clean water policies.
Abundance, Distribution and Drivers of Microplastic Contaminant in Urban River Environments
Researchers surveyed microplastic distribution in urban river environments and identified key drivers of accumulation hotspots, finding that land use, hydrology, and infrastructure factors concentrated microplastics at predictable locations that could inform targeted management interventions.
Assessment of the groundwater recharge processes of a shallow and deep aquifer system (Maggiore Valley, Northwest Italy): a hydrogeochemical and isotopic approach
Researchers analyzed water chemistry and isotopes across shallow and deep groundwater systems in northwest Italy, tracing how water from distant mountain recharge zones mixes before reaching a heavily used drinking water well field. The study clarifies potential pathways for pollutants to reach drinking water supplies, providing critical information for protecting this major regional water resource.
Assessment of vulnerabilities of central himalayan springs towards microplastic pollution.
This research assessed how vulnerable springs in the central Himalayas are to microplastic contamination, identifying environmental and geographic factors that increase exposure risk. Mountain springs are critical drinking water sources for millions of people, so understanding their susceptibility to plastic pollution has direct public health implications.
Spatio-temporal evaluation of trace element contamination using multivariate statistical techniques and health risk assessment in groundwater, Khulais, Saudi Arabia
Researchers assessed trace element contamination in groundwater across 19 sites in the Khulais region of Saudi Arabia over two seasons. Using statistical analysis, they identified both agricultural runoff and natural geological sources as contributors to elevated levels of toxic metals in the water. The health risk assessment found potential non-carcinogenic and carcinogenic risks for local populations who rely on this groundwater for drinking and agriculture.

Predicting microplastic masses in river networks with high spatial resolution at country level
Scientists built a computer model to predict microplastic levels in every section of Switzerland's rivers and lakes for seven different plastic types. They found that the amount of microplastics in any given spot depends heavily on local features like nearby lakes, land use, and river connections, not just population density. This kind of detailed mapping helps identify pollution hotspots and assess where human exposure through drinking water might be highest.

Scientists mapped the distribution and characteristics of microplastics throughout the Han River watershed in South Korea, including tributaries and sections that serve as drinking water sources, and found widespread contamination varying by location and flow conditions.

Spatial Variability and Combined Risk of Metal elements and Microplastics along the River Severn (UK)
Scientists found that the River Severn in the UK contains both toxic metals (like lead and zinc) and microplastics throughout its length, with the highest pollution levels near cities and old mining areas. These pollutants tend to cluster together in "hotspots," meaning people living downstream could be exposed to multiple types of contamination at once through their drinking water. This research helps identify the most polluted areas so water managers can focus cleanup efforts where they're needed most to protect public health.
