A water sample refers to a representative portion of a specific water body that is taken discontinuously or continuously to examine various specified characteristics in the water body. From the perspective of sampling time、 it can be divided into instantaneous water samples and mixed water samples; From the perspective of sampling concentration、 it can be divided into surface water samples、 middle water samples、 and bottom water samples; From the testing items、 it can be divided into water quality samples and biological water samples. The representativeness of water samples is a prerequisite for the accuracy of analysis and testing and the reliability of evaluation conclusions. In order to ensure the representativeness of water samples、 it is necessary to select representative monitoring sections or monitoring points、 adopt standardized sampling methods、 collect samples within the specified time period、 and timely and effectively stabilize the collected water samples
