Sources and Consequences of Groundwater Contamination
Summary
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.
Groundwater contamination is a global problem that has a significant impact on human health and ecological services. Studies reported in this special issue focus on contaminants in groundwater of geogenic and anthropogenic origin distributed over a wide geographic range, with contributions from researchers studying groundwater contamination in India, China, Pakistan, Turkey, Ethiopia, and Nigeria. Thus, this special issue reports on the latest research conducted in the eastern hemisphere on the sources and scale of groundwater contamination and the consequences for human health and the environment, as well as technologies for removing selected contaminants from groundwater. In this article, the state of the science on groundwater contamination is reviewed, and the papers published in this special issue are summarized in terms of their contributions to the literature. Finally, some key issues for advancing research on groundwater contamination are proposed.

A Review of the Status, Effects, Prevention, and Remediation of Groundwater Contamination for Sustainable Environment
This review examines the state of groundwater contamination worldwide, including pollution from industrial chemicals, pesticides, and plastic-related contaminants. Unsafe water contributed to 1.2 million deaths globally in 2019, with low-income countries disproportionately affected. The paper discusses various cleanup methods and emphasizes the urgent need to protect groundwater, which is a primary source of drinking water for billions of people.
Environmental chemistry, toxicity and health risk assessment of groundwater: Environmental persistence and management strategies
This review examines groundwater contamination from heavy metals, pesticides, microplastics, and emerging pollutants, assessing health risks and highlighting the need for integrated management strategies to protect this critical freshwater resource.
Groundwater quality: global challenges, emerging threats and novel approaches
This review highlights global groundwater quality challenges including emerging contaminants and antimicrobial resistance, emphasizing the need for significantly improved monitoring to identify and mitigate threats from historical and future pollution sources.
Groundwater Pollution and Contamination: Sources, Impacts, Management, and the Integration of AI/ML for Future Solutions
This review covers the sources, health impacts, and management strategies for groundwater pollution, including contamination from agricultural runoff, industrial waste, and landfill leachate. While broadly focused on water quality, the paper is relevant to microplastic concerns because contaminated groundwater is a drinking water source for billions of people, and emerging pollutants including microplastics are increasingly found in these systems.
Microplastic accumulation in groundwater: Data-scaled insights and future research
This data-driven review of nearly 400 groundwater samples worldwide found that microplastics are present in both shallow and deep groundwater, with open groundwater sources showing higher contamination than enclosed aquifers. The findings are relevant to human health because groundwater supplies drinking water for billions of people, and the study identifies key gaps in our understanding of how microplastics accumulate underground.
