Deciding on the amount and type of restoration work is a key question. It requires scientific and technical understanding of the contamination and the risks posed. It may also require engagement with the local community and other agencies. Drawing on our site restoration experience, Quintessa can bring to bear a mix of key skills, “from data to decisions”. Our expertise ranges from detailed understanding of contaminant behaviour in the environment and human and environmental risks to community and stakeholder engagement and decision-aiding techniques.
