Antimony (Sb) and arsenic (As) concentrations were measured in the water column and sediments at Bakers Creek (a historical point source of contamination) and at seven sites along the Macleay River from Georges Junction to Jerseyville.

Water column Sb at Bakers Creek ranged from 37 to 96 times the ANZECC guidelines for healthy aquatic ecosystems, but no site on the Macleay River exceeded the ANZECC Sb trigger value for healthy aquatic ecosystems.

Water column As at Bakers Creek ranged from 1.4 to 2.7 times the ANZECC trigger value for healthy aquatic ecosystems. The Macleay River at Jerseyville exceeded the ANZECC As trigger value for healthy aquatic ecosystems once (November 2015).

Bakers Creek

Sediment Sb at Bakers Creek ranged from 72 to 164 times the national sediment low guideline value. The national sediment low guideline value was exceeded at Georges Junction, Bellbrook, Kinchela and Jerseyville.

Sediment As at Bakers Creek ranged from 4.4 to 7 times the national sediment low guideline value. No site in the Macleay River exceeded the national sediment low guideline value during the study period.

The Macleay River Working Group comprises state and local government, industry, researchers and the community and provides a forum to discuss the As and Sb contamination issue. Derelict Mines has commissioned an assessment of historic workings of As and Sb in the Macleay Catchment and the final report is expected in early 2017.
