Short overwiew (longer version in German)

The patented Shuttle-Guard-System protects the aquifer from contact with the chemically altered casing water and enables a contimous groundwater monitoring via sensors and depth-oriented, isobar retrieval of unadulterated groundwater samples.

The sampling system consists of two main components:

  • a GWMon-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 is able to measure temperature, water conductivity, pressure, pH and redox potential 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. It can be combined with the GW-Station (basis version without sensors).
