Title:
GROUNDWATER SAMPLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/043381
Kind Code:
A1
Abstract:
The present invention relates to a water sampling device that can accurately collect corresponding groundwater samples from a desired target depth in groundwater, in which the opening and closing of a sampling bottle at a certain depth can be remotely controlled through two springs and two strings that can eliminate the restoring force of springs. In particular, the device of the present invention can accurately collect corresponding groundwater samples from a desired target depth in groundwater and, during retrieval after sampling, the inflow of contaminants or groundwater at other different depths can be prevented, and thus the reliability of the collected samples is excellent. In addition, the water sampling device according to the present invention enables precise sampling of groundwater containing DNAPL substances, such as TCE or PCE, located at relatively deep depths in groundwater.
