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.
Groundwater Vulnerability Assessment to Cemeteries Pollution through GIS-Based DRASTIC Index
Researchers used geographic information system (GIS) tools and the DRASTIC index to assess how vulnerable groundwater is to pollution from cemeteries. The study mapped areas where burial practices could allow contaminants from decomposing materials to reach underground water sources. The findings provide a framework for evaluating environmental risks associated with cemetery locations and protecting drinking water resources.

Using AHP multi-criteria analysis with GIS remote sensing data, groundwater potential zones in Uttarakhand, India were delineated, with 28.67% of the state classified as having good potential and 12.37% as very good potential for groundwater development.
Analysis of Groundwater Quality in the Coastal Aquifer of the Effutu Municipality, Ghana
Researchers analyzed groundwater quality in the coastal aquifer of the Effutu Municipality, Ghana, comparing water quality parameters against WHO permissible limits and using principal component analysis to identify key drivers of water quality variation. The study provides data to assess groundwater suitability for domestic and drinking purposes in an area facing freshwater management challenges.
GIS Analysis of Organo-Contaminants and Iron Linked to Groundwater and Sediment at Boreholes in Aluu, Delta Region, Nigeria
Researchers used GIS spatial analysis to characterize organo-contaminant and iron concentrations in groundwater and borehole sediments from 10 sites at 45 m depth in Aluu, Nigeria, providing baseline data on contamination sources linked to gastrointestinal illness in communities relying on this groundwater for drinking.
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.
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 Groundwater Contamination in the Southeastern Coast of Brazil: A Potential Threat to Human Health in Marica Municipality
Researchers assessed groundwater contamination in Marica Municipality along Brazil's southeastern coast, finding that rapid urbanization and inadequate sanitation have led to significant sewage pollution. The study suggests that elevated levels of dissolved organic carbon, nutrients, and bacteria in the aquifers pose a potential threat to public health, since groundwater serves as the primary freshwater source for local residents.
Coastal Vulnerability Assessment: A Case Study of the Nigerian Coastline
Researchers assessed the vulnerability of the Nigerian coastline to sea-level rise and associated hazards including erosion, flooding, and saltwater intrusion using analytical methods. The study quantified and classified coastal vulnerability across the Nigerian shoreline to support evidence-based coastal management.
Groundwater dependent ecosystems in coastal Mediterranean regions: Characterization, challenges and management for their protection
Researchers reviewed the status of coastal groundwater-dependent ecosystems (wetlands and lagoons sustained by aquifer discharge) in Mediterranean regions, identifying plastic pollution, over-extraction, and weak governance as critical threats, and calling for new legal definitions and transdisciplinary management frameworks to protect them.
Hydrogeochemistry and Health Risks Assessment of Some Groundwaters Suitability for Drinking Within the Urban Region of Unguja Island, Zanzibar
Researchers assessed groundwater quality and health risks in Zanzibar, finding contamination from nitrates, heavy metals, and microbial sources in wells used for drinking. While focused on chemical and microbial contaminants, groundwater in coastal regions is increasingly being assessed for microplastic contamination as well.
Human health risk perspective study on characterization, quantification and spatial distribution of microplastics in surface water, groundwater and coastal sediments of thickly populated Chennai coast of South India
Researchers characterized microplastics in surface water, groundwater, and coastal sediments along Chennai's densely populated coast in South India, finding widespread contamination with fibers as the dominant shape and identifying urban proximity as a key factor in microplastic abundance.
Assessing microplastic pollution vulnerability in a protected coastal lagoon in the Mediterranean Coast of Egypt using GIS modeling
Researchers measured microplastic distribution in Lake Burullus, a protected coastal lagoon in Egypt, and used GIS modeling to assess vulnerability to non-point source pollution. Microplastic concentrations near drainage points were five times higher than in open water, with eight thermoplastic polymer types identified, and vulnerability maps revealed drainage proximity as the dominant risk factor.
Patterns and variability in the microplastic contamination along the southwest coast of India with emphasis on submarine groundwater discharge sites
Researchers analyzed microplastic contamination in beach sediments along the southwest coast of India, including submarine groundwater discharge (SGD) sites, finding average loads of 230 particles per 100 g dominated by blue polyethylene fibers. Both SGD and non-SGD sites showed microplastic contamination, with SGD zones potentially acting as conduits for microplastics from groundwater to the coast.
Microplastic contamination in urban groundwater: Risk assessment, citizen perception and policy imperatives – a case study of Kozhikode City, Kerala State, India
Researchers examined microplastic contamination in 120 open wells used for drinking water in an Indian city and found particles present in over 73% of samples. Polypropylene was the most common polymer detected, and concentrations varied widely across the city. The study also surveyed citizen awareness and found that most residents were unaware of microplastic contamination in their water supply, pointing to the need for public education and policy action.

This review examines how saltwater intrusion into coastal groundwater aquifers in dry climates affects the behavior and movement of heavy metals. While focused on heavy metals rather than microplastics directly, the findings are relevant because microplastics in these same aquifers can carry and release heavy metals as salinity changes, potentially contaminating drinking water sources for coastal communities.
