Phases: Historical and technical assessment
Building costs: -
From 1980 until 2013, Marly was home to a cutting-edge factory producing film and photographic paper. Owing to the site's industrial past, it was deemed to require further investigation and was entered in the Register of Contaminated Sites. Ecosens carried out a historical survey of the site in order to determine which hazardous substances had been deployed in the past, where they had been used and in what quantities. This information was compiled in a “hotspots” matrix to give an overview of the potential areas of contamination and form the basis for planning the technical assessment.
During the technical assessment, excavation shafts and rotary coring were carried out and evaluated onsite, and samples of earth, soil air and groundwater were taken and analysed for contaminants. The structure of the building itself was also examined for evidence of contamination.
