Disposal of coal mine wastewater to the headwaters of a high conservation value waterway caused water pollution and ecological degradation of a World Heritage listed upland river. Below the mine, macroinvertebrate family richness decreased by 65% and abundance by 90%. Upstream of the waste discharge had very low electrical conductivity (EC) of 30.0µS/cm and pH was acidic (5.6) in contrast to that below the mine which showed EC 11 times higher (342 µS/cm) and a shift in pH to 7.2.
