The global outbreak of coronavirus infectious disease-2019(COVID-19)draws attentions in the transport and spread of Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2)in aerosols,wastewater,surface water and solid wastes.As pathogens eventually enter the subsurface system,e.g.,soils in the vadose zone and groundwater in the aquifers,they might survive for a prolonged period of time owing to the uniqueness of subsurface environment.In addition,pathogens can transport in groundwater and contaminate surrounding drinking water sources,possessing long-term and concealed risks to human society.This work critically reviews the influential factors of pathogen migration,unravelling the impacts of pathogenic characteristics,vadose zone physiochemical properties and hydrological variables on the migration of typical pathogens in subsurface system.An assessment algorithm and two rating/weighting schemes are proposed to evaluate the migration abilities and risks of pathogens in subsurface environ-ment.As there is still no evidence about the presence and distribution of SARS-CoV-2 in the vadose zones and aquifers,this study also discusses the migration potential and behavior of SARS-CoV-2 viruses in sub-surface environment,offering prospective clues and suggestions for its potential risks in drinking water and effective prevention and control from hydrogeological points of view.
