The land was adjacent to the former Berger Paint Factory located at former Alfred Street, Rhodes, refer to Attachment 1. Past activities carried out in the paint factory resulted in the factory site as well as the adjoining Homebush Bay sediments being heavily contaminated with lead.
The factory site was remediated and redeveloped and now forms part of the Rhodes Shopping Centre. The adjoining bay sediments area was declared an Investigation Area and subsequently a Remediation Site (No.15013 dated 19 November 2002 and No.21050 dated 17 December 2003, respectively). The main concern was very high concentrations of lead in the surface sediments.
Orica entered into a voluntary remediation agreement on 3 May 2004. The remediation requires the removal of the surface sediments to a depth of no less than 30 cm or to the underlying shale bedrock. The remediated area will then be backfilled with clean material that is mixed with organic matter (“the clean capping layer”) and revegetated with mangrove.
The remediation of the bay sediments was completed in the second half of 2006. Levels of lead at the base of the excavation vary and remain high. The actual levels of lead and the sampling locations are shown in Attachment 3 and Attachment 4, respectively. The lead contamination in the sediments at depth however should pose no threat to human health or to the environment as long as the clean capping layer is in place and remains intact. |
