In connection with the LIFE project, between 21 and 22 October 2019, automatic groundwater probes were installed in groundwater monitoring wells, by ERTI. Automatic measurements are performed in 14 sample areas, replacing manual measurements. The probes measure the actual groundwater level every 15 minutes, which is stored in memory, so data can be read at any time. We check the condition of the devices every year with the help of ERTI.
