Geophysical Survey in Lavrion City for the Detection of Water Resources and Underground Voids or Cavities

Lavrio city with the great history in mining and metallurgical activity from ancient times has the interest to exploit water resources and detect possible tunnels or voids in certain places where historical data indicate. A geophysical survey with 2D resistivity soundings detected the overall geological-hydrogeological environment. A combination of electrical resistivity tomography and georadar profiles has given a detailed picture of the underground indicating areas of fracture zones or cavities. Finally two drillings are proposed, one for water exploitation and one both to detect the stratigraphy and the fracture zones and exploit water of low quantity and quality.
