The collection of surface water samples is the key link of water quality monitoring,which directly affects the accuracy and reliability of subsequent water quality analysis.In order to ensure the quality of sampling,it is necessary to understand and apply the surface water sampling technology reasonably.This paper emphasizes the quality control measures in the sampling process.Through reasonable selection of sampling points,sampling equipment and storage methods,as well as strict compliance with sampling procedures,it is possible to ensure that the collected water samples are representative and comparable.These measures provide a reliable technical basis for surface water quality analysis,contribute to the accurate assessment of water environmental quality,and provide a scientific basis for water resources management and protection.
