Contaminated land: prepare environmental due diligence
Potentially contaminated land needs an activity history, available environmental records and a defined future use. A geotechnical report is not a complete contamination assessment. France and Switzerland have different site-register and remediation frameworks. The due-diligence sheet connects reports and sale documents without certifying clean soil or deciding which party ultimately bears investigation and remediation costs.
