Dredging of Port Phillip Bay weekly update

|All dredged sediment will be placed in the Port of Melbourne Dredged Material Ground and capped with clean sand from the south of Port Phillip Bay.|
A small backhoe dredge will remove the sediment and a dredge vessel or Trailing Suction Hopper Dredge will remove the clean sand that will be used to cap the contaminated sediment.
Six northern beaches will be tested weekly for 12 heavy metals from November 2009 to June 2010. The results will be available below.
Results from a similar 19 month program conducted during the Channel Deepening Project showed that the Bay’s beaches were in very good condition and that metal and organic chemicals readings were consistent with historic levels for the Bay.
The program must comply with an Environmental Management Plan (EMP) and the Office of the Environmental Monitor will scrutinise dredging works to ensure they follow the requirements set out in the EMP. To assist with this task, the Office has commissioned two independent audits. The first of these, for the period 19 October 2009 to 6 August 2010 is available here. The second report, covering the period 7 August 2010 to 18 January 2011, is available here.
