Multi-parameter monitoring of the old saltworks in Urcuit (Bayonne)

More precisely, Ineris will monitor:

• water characteristics (temperature and conductivity), in order to confirm that the former saltworks is not contaminating surface aquifers at the site’s output area. It will also check for accidental discharges of brine into the environment in the event of a cavity collapse;
• the pressure in three hydraulically-connected cavities, in order to watch out for changes in risk areas where collapses could be considerable.

The monitoring mechanism integrates a warning system that enables the evacuation of the site in the event of sudden and repeated changes in pressure (a possible indicator of collapse). The warning system also enables the deployment of means to control the discharge of brine into the environment in the event of collapse.
The monitoring project and all the transmitted instrument data are managed via the e.cenaris web platform, to enable remote monitoring and management of changes at the site.
