Our on-site interventions

Data acquisition, monitoring, data processing are all key steps in

  • characterising aquifers and related water tables,
  • establishing reliable, relevant recommendations

An indispensable prerequisite for any calculation, the acquisition of field data must be done in line with current regulations and good practice.

The relevance of the investigation programmes and the quality of their implementation condition the representativeness and relevance of the conclusions of our analysis and expertise assignments.

Optimising investigation campaigns

Field data acquisition is carried out by Fondasol's hydrogeological engineers, with the support of geotechnical investigation teams trained in hydrogeological issues.

This approach combining expertise from multiple fields enables us to optimise the investigation campaigns. This is also the approach for our decision aid tool Solscore, which provides a trend and immediate information on the risks linked to the subsurface conditions by drawing on Fondasol's database.

All our campaigns are carried out in compliance with the specific regulations  linked to the conduct of investigations or taking of samples in the works and final phases (Environment Code or Water Law, etc.).
