Abstract
The disclosure provides a method for sampling groundwater. The method includes extracting groundwater from a monitoring well in a first flow rate; monitoring groundwater level in real-time, and calculating a decrease of the groundwater level during the extracting in the first flow rate based on the real-time monitored groundwater level; when the decrease of the groundwater level is equal to a first value, extracting groundwater from the monitoring well in a second flow rate, the second flow rate being smaller than the first flow rate; and when the groundwater level is in an equilibration state, extracting groundwater from the monitoring well and using the extracted groundwater at this time as a representative groundwater.
