Residents in Ipswich have renewed complaints of contaminated water flowing from a dump west of Brisbane into nearby Six Mile Creek, which then flows into the Bremer and Brisbane rivers.

The Cleanaway New Chum Solid Waste Landfill facility has been fined twice in the past for breaching water flow restrictions, with penalties totalling just over $26,500.

Ipswich Residents Against Toxic Environments secretary Geoff Yarham told the ABC that the penalties were a slap on the wrist for a company of that size.
