Our flagship product is NOVEL-EM monitoring system - intended for mine site waste area
water monitoring, leakage detection and improving environmental safety. System is in use
at several Finnish mine sites. Monitoring is based on accurate indirect measurements
of ground water layer electrical conductivity, integration of other related
measurements and deducing the water quality and chemistry changes. Also embankment dam structures
can be investigated and leakage points and routes detected.
