Application of high-resolution site characterisation tools and sampling methods for assessing microplastic migration beneath MSW dumpsites
Researchers used advanced site characterization tools, including cone penetration testing and hydraulic profiling, to track how microplastics migrate from old waste dump sites into deeper soil layers and groundwater. They found microplastics at significant depths, with high-permeability zones serving as preferential pathways for particle migration. The study demonstrates that legacy waste sites may be ongoing sources of subsurface microplastic contamination.

Researchers assessed water quality in the upper Ganges River near Haridwar using GIS-based analysis, finding that land use changes including urbanization and agriculture significantly impacted water quality parameters along a 78-kilometer stretch.
Evaluation of Soil Pollution Levels in Al-Qadisiyah Governorate, Iraq Using Contamination Index and GIS
Researchers used geo-accumulation index analysis and GIS mapping to evaluate heavy metal contamination from cadmium, nickel, lead, and zinc in 28 soil profiles collected from Al-Shamiyah city in Al-Qadisiyah Governorate, Iraq. They found that cadmium showed the highest contamination levels, ranging from non-polluted to significantly heavily polluted, with nickel concentrations elevated near major drainage infrastructure.
Assessment of potentially toxic elements in groundwater through interpolation, pollution indices, and chemometric techniques in Dehradun in Uttarakhand State
Researchers assessed potentially toxic heavy metals (including iron, cadmium, lead, and chromium) in groundwater across an industrial region of northern India, finding contamination levels linked to agricultural runoff, industrial discharge, and land use patterns that pose ongoing health risks to local communities.
Identification of Groundwater Pollution Characteristics and Health Risk Assessment of a Landfill in a Low Permeability Area
Researchers assessed groundwater quality and health risks near a landfill in a low-permeability red-bed area of Southwest China, finding elevated concentrations of heavy metals and organic pollutants in shallow aquifers used for drinking water by nearby rural residents.
Mapping the impacts of the anthropogenic activities and seawater intrusion on the shallow coastal aquifer of Port Said, Egypt
Researchers used remote sensing, geophysical surveys, and water chemistry analysis to map groundwater contamination in the coastal area of Port Said, Egypt. They found that anthropogenic activities like fish farming and urbanization, combined with seawater intrusion, have significantly degraded groundwater quality. The study provides an integrated framework for understanding how human activity and saltwater encroachment jointly threaten freshwater resources in coastal regions.

Not relevant to microplastics — this paper presents a methodology for designing hydrogeological maps of surface water and groundwater systems in northern Italy.
Implementing a GIS-Based Digital Atlas of Agricultural Plastics to Reduce Their Environmental Footprint: Part II, an Inductive Approach
Researchers implemented a GIS-based digital atlas of agricultural plastics using an inductive approach, aiming to map and reduce the environmental footprint of plastic use in farming and address alarming levels of terrestrial plastic contamination.
Portable X-ray fluorescence (pXRF) analysis of heavy metal contamination in church graveyards with contrasting soil types
Researchers used portable X-ray scanners to measure heavy metal levels in soil at two historic UK church graveyards, finding elevated iron, lead, manganese, and other metals extending up to 2 meters deep — concentrations that could pose risks for communities where old burial grounds have been converted to housing.

Groundwater systems under siege: The silent invasion of microplastics and cock-tails worldwide
This review reveals that groundwater, a critical drinking water source for billions of people, is increasingly contaminated with microplastics from surface pollution seeping downward through soil. Unlike ocean and river pollution, groundwater microplastic contamination has received far less research attention, leaving major gaps in understanding how plastics migrate underground. The findings are alarming because contaminated groundwater directly enters drinking water supplies with little to no treatment in many regions.
