Synergy successfully executed a comprehensive remediation scope addressing significant contamination, including friable and non-friable asbestos, heavy metals, and landfill gases. This ensured the site’s suitability for future use. The project involved the remediation of significant contamination issues due to the site's previous unlicensed use as a landfill and former chicken farm.

Contaminants included non-friable asbestos, heavy metals, PFAS, microbials, and landfill gases. The selected remediation strategy involved removing specific fill materials containing both friable and non-friable asbestos, along with oversize demolition wastes. Following disposal, the landfill area was reshaped before installing the cover layer to ensure clean water diversion and maintain the integrity of the cap (with a 50-year lifespan). Key activities, including reviews, inspections, monitoring, sampling, and testing, confirmed the successful completion of the remediation. The site is now suitable for handover to NSW National Parks and Wildlife Services.

Synergy provided deliverables in appropriate timeframes and worked in a proactive manner during the project. Additionally, Synergy managed unexpected circumstances such as ecological incidents as a result of vandalism and unexpected finds resulting in re-design in an efficient and effective manner. As a result, would recommend Synergy as a remediation contractor for future projects
