Short overwiew (longer version in German)

The patented non-adulterating groundwater sampling system protects the aquifer from contact with the chemically altered casing water and enables a depth-oriented, isobar retrieval of unadulterated groundwater samples.

The sampling system consists of two main components:

  • a GW-Station that is permanently installed in the well screen of the monitoring wells and creates a vertically separated space that prevents mass transfer between aquifer and casing water and
  • a mobile GW-Shuttle for all monitoring wells that docks at the GW-Stations, takes up a water sample under in-situ pressure (isobar sampling) and transports it to ground level.

The system is applicable for retrofitting existing intact monitoring wells constructed conforming to standards.
