C- 2 Golder Associates (2001) conducted an audit and suggested additional monitoring bores and some remediation work. The monitoring bores have been constructed, but the remediation work has not been done. Continued monitoring (IT Environmental 2004) suggests that the plume is continuing to expand. Wills Terrace stormwater outfall Three monitoring bores were drilled in the Todd River near the Wills Terrace stormwater outfall on behalf of Shell Australia to check for hydrocarbons carried down the drain from the Shell depot. It should be noted that the Shell depot is not the only possible source of this contamination. Summarised results are shown in Table C-1 . Hydrocarbons have been detected erratically.

(3) The bore is described as dry, but the SWL in MW32 clearly shows that water level is above the bottom of the screen. Presumably the bore has sanded up.
