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.

Answer

Does Swiss transfer of a listed site need separate review?

LPE32dbis has its own transfer or division conditions. Read the actual listed status and legal branch rather than presuming universal prohibition.
