A Narrative Review of Groundwater and Soil Pollution

Abstract

In accordance with the migration and transformation laws of pollutants in soil and groundwater, the research progress of chemical fertilizers, pesticides, and sewage irrigation is reviewed systematically from three perspectives: the topsoil layer, the underground aquifer, and the unsaturated zone. The results of the study of migration and transformation in various water layers and unsaturated soils illuminate the current research's problems and future directions.
