The rising harmfulness of plastic polymer nanoparticles threatens the crucial water source known as groundwater. The underground space receives plastic polymer nanoparticles through environmental airfalls and water treatment residue while plastic waste breaks down to enter the system where the particles migrate through sediments and subsurface water strata. Both recent and long-term movements of plastic polymer nanoparticles throughout subsurface environments remain insufficiently understood worldwide. The review examines plastic polymer nanoparticle actions within subsurface environments by studying their movement mechanisms alongside their effects on groundwater pollution levels. Research with soil columns in laboratory settings and field trials and numerical models demonstrates that the movement of nanoparticles depends upon three main factors: particle sizes between 10-200 nm as well as soil texture characteristics and organic carbon content. The combination of increased DOC concentrations leads to stable particles yet clay-rich substrates show a tendency to keep particles within their boundaries. Continuous fluid retention in aquifers ends in concentrated contamination areas. Critical physical as well as chemical processes determine nanoparticle movements in the environment thus posing major threats to water supply networks. The evaluation stresses the importance of combined research fields and enhanced waste disposal practices and intensified governmental regulations because they minimize these dangers. The research states that assessments of groundwater vulnerability need to incorporate knowledge about nanoparticle behavior.
