Mangrove Mountain Advisory Sub-Committee - Thursday 17 September 2026

Topics

• PFAS detections keep focus on Ourimbah Creek drinking water catchment
  The advisory Subcommittee is seeking more information about PFAS detections at monitoring sites 5, 16 and 17 while Council continues the catchment management plan.
  The issue concerns environmental monitoring and protection of a drinking water catchment, with further results to be provided to the Subcommittee.
• Mangrove Mountain landfill contamination status remains under review
  The Subcommittee continued considering whether the Mangrove Mountain landfill site should be classified as contaminated land, with a possible site visit proposed.
  The landfill's environmental status and any future inspection are significant for nearby residents and catchment oversight.
• EPA briefing sought on PFAS and groundwater results
  The Subcommittee may invite senior Environment Protection Authority staff to a future meeting and will receive publicly available EPA groundwater monitoring results.
  A regulator briefing could clarify monitoring results and the response to PFAS detections for the local community.

Decisions

• PFAS Management Plan outcomes noted
  The Subcommittee recommended that Council note the outcomes of ongoing PFAS monitoring in the Ourimbah Creek Catchment and the continued implementation of the Ourimbah Creek Catchment PFAS Management Plan.
  The monitoring relates to environmental conditions and drinking water protection in the catchment.
• Further PFAS and EPA information to be provided
  Publicly available Environment Protection Authority groundwater monitoring results will be provided to the Subcommittee, along with further information about detections at monitoring sites 5, 16 and 17.
  Residents will have a clearer basis for understanding PFAS detections and groundwater monitoring results.
• Catchment boundary map to be circulated
  A higher-resolution map of the drinking water catchment boundary was tabled and will be circulated electronically.
  The map will help residents identify the area covered by drinking water catchment protections and monitoring.
• Potential landfill site visit
  Council officers will request that a landfill site visit be arranged, subject to approval from Verde Terra Pty Ltd.
  A site visit could provide the Subcommittee with more direct information about the landfill and its environmental management.

Discussion

• Mangrove Mountain landfill contamination status
  The Subcommittee continued considering the classification of the Mangrove Mountain landfill site as contaminated land.
  The classification may be relevant to environmental oversight, remediation discussions and community understanding of risks.

  The meeting addressed ongoing monitoring, PFAS detections at sites 5, 16 and 17, groundwater results and implementation of the catchment management plan.
  PFAS monitoring is directly relevant to catchment health and drinking water protection.
• Possible future EPA participation
  Environment Protection Authority attendance at a future Subcommittee meeting remains subject to approval by senior EPA staff.
  A future EPA briefing could provide residents with information from the state environmental regulator.
