❓ A parliamentary question regarding the potential contamination of the Yarragadee aquifer by the Dalyellup Residue Disposal Facility. The Minister assures that contamination is highly unlikely due to natural up-welling and westward groundwater flow.

QuestionView source ↗
I refer to the Dalyellup Residue Disposal Facility, sited south of Bunbury and operated by Millennium Organic Chemicals as a disposal site for mine and process waste -
(1) Will the Minister table the company’s ‘Shallow Groundwater Assessment’ reports for the past five years, including the most recent Groundwater assessment report?
(2) Does the Minister consider that the disposal site poses zero risk of introducing radionuclides, heavy metals or dissolved solids into the Yarragadee aquifer?
(3) If yes, will the Minister table evidence to support this supposition?

2. The Department of Environmental Protection has advised it is highly unlikely that the disposal of material at the Dalyellup site will introduce radionuclides, heavy metals or dissolved solids into the Yarragadee aquifer because of the natural up-welling of groundwater in the area, which prevents potential contamination. Groundwater results show that groundwater in the disposal site vicinity is moving westwards towards the ocean, and there is no impact on groundwater bores to the east. Evidence to support this view is provided in the tabled reports. 3. Answered by (2).
