INTERGEO will lead the compilation and preparation of water technologies, contribute a Greek case study for comparison and benchmarking, and support the case studies with their experience in environmental technologies.

INTERGEO Environmental Technology Ltd. was founded in 1987 aiming to provide consulting services on environmental technology and ground engineering. Today, INTERGEO is represented by 30 offices in 24 countries worldwide. INTERGEO is engaged in hundreds of projects throughout Europe and worldwide. INTERGEO companies have successfully performed more than 4.800 investigations projects and completed more than 1.200 soil and groundwater remediation projects. The key personnel consist of engineering geologists, civil engineers, geotechnical engineers, hydrogeologists, mining engineers, mechanical engineers, environmental scientists, chemists, biologists, physicists, geophysicists and drilling specialists. The high specialization and experience of the employed personnel guarantees efficient execution of the project concerned. We work for a broad range of clients in the private and public sectors. Our list includes oil and gas industries, real estate companies, mining and construction companies, municipalities, insurance companies, etc. The aim of the company is to provide excellent technical services combining the real needs of the customer with cost-effective solutions.


  • Environmental Site Assessment: Water - Soil - Air sampling,
  • Analytical services - fixed and mobile environmental laboratories
  • Soil and groundwater remediation with physical, chemical and biological methods
  • Hydrogeological, Geophysical and Water Management investigations
  • Environmental Risk Assessment in industrial installations, procedures and accidents

Especially in the field of bioremediation INTERGEO Group has developed and applied a series of different types of biopiles for on and off site applications in order to remediate contaminated soil and sludges stemming from industrial process in over 200 cases. Furthermore, in situ remediation techniques (Soil Vapour Extraction, Bioventing, Air-/Biosparging, Bioslurping) have been extensively implemented throughout Europe in over 500 cases of contaminated soils.

INTERGEO ENVIRONMENTAL TECHNOLOGY LTD. was established in Thessaloniki, Greece in 1990, as a subsidiary company of INTERGEO SALZBURG, aiming to provide the same services as the parent company and to transfer experience and know-how in Greece on the of environmental and geotechnical-engineering fields. For the proper execution of all these projects an INTERGEO branch office was introduced in Athens in 1998 whereas local company representatives have been employed in Alexandroupolis and on the islands of Corfu, Crete, Mytilene, Rhodes and Zakynthos.

The key personnel consist of geologists, hydrogeologists, environmental scientists, chemists and process engineers.

INTERGEO ENVIRONMENTAL TECHNOLOGY LTD.has been engaged in many projects all over the Greek territory as well as in other neighboring countries like Southern Cyprus, Bulgaria, Serbia and Albania.
