In this paper,the sources and distribution characteristics of heavy metals in surface water and groundwater were studied.Heavy metals come from natural and anthropogenic sources and pose a significant risk to ecosystems and human health.Factors such as pH value,redox conditions and aquifer geology affect its distribution pattern,and pollution hotspots generally exist in industrial activities,agricultural activities and urban runoff areas.Then,heavy metal concentration monitoring techniques were explored,involving sampling analysis methods and remote sensing techniques,and remediation strategies including phytoremediation,chemical precipitation and bioremediation to mitigate heavy metal pollution and protect water resources.
