From surface to aquifer: a global synthesis of landfill leachate composition and its impact on groundwater systems

Landfill Leachate Generation, Migration and Impacts on Soil and Groundwater Systems: A Review of Global, African and Nigerian Perspective

Municipal solid waste generation is rising rapidly worldwide, and in many low- and middle income countries disposal remains dominated by open dumping without engineered containment, creating persistent conditions for the generation and uncontrolled migration of landfill leachate. This review synthesises global, Afric...

Critical review of leachate pathways, groundwater contamination, and health risks in tropical urban aquifers

Rapid, under-serviced urbanization across the tropical belt has left many cities dependent on open dumps. These dumps and poorly engineered landfills often sit above shallow, heavily used aquifers. This review uses the Doddabidarakallu municipal solid waste facility in Bengaluru, India, as an illustrative anchor case....

Emerging Contaminants in Groundwater Resources: From Occurrence and Risk Assessment to Advanced Remediation

Groundwater is a major source of drinking water, irrigation and industrial supply, yet its apparent protection from surface disturbances can be misleading. A diverse group of emerging contaminants (ECs)—including pharmaceuticals and personal-care products, endocrine-disrupting compounds, pesticides, per- and polyfluoro...

Seasonal dynamics of heavy metal concentrations from municipal solid waste landfill leachate in Varanasi: impact on groundwater quality and human health

Effects of Landfill Leachate on Groundwater Quality in Northern South Africa

In many African countries such as South Africa, untreated groundwater is one of the most utilised resources for domestic, agricultural, industrial, and mining purposes. However, with the growing population, there is a concern about the interconnectivity between waste disposal and water quality. The absence of sanitary...

Sources, Transformation, and Fate of Groundwater Nitrate Under Intensive Anthropogenic Pressures in the Lower Yellow River Basin: Insights From Hydrochemistry and Multi‐Isotope Analysis

Enhanced human activities have increased nitrate contamination in groundwater, threatening water‐supply safety and public health. This study examined nitrate sources and transformation processes in 29 shallow groundwater samples from the lower Yellow River Basin, a region subject to intensive agricultural, industrial,...
