The "invisible waters" of Rome : monitoring of groundwater, a precious resource to be protected and enhanced

The Geological Survey of Italy and the Municipality of Rome signed an agreement to monitor the groundwater of the city. The subsoil of the capital of Italy is not only rich in ruins of the Roman civilization, but also in groundwater. The monitoring network has more than 200 monitoring points between wells and piezometers, some of which are continuously monitored. Groundwater level, temperature, pH and electric conductivity data are collected and recorded on a web app that will soon be available online. In order to raise the public awareness of this activity, ISPRA produced a documentary video entitled "What flows under our feet?" in which the monitoring details are explained.
