Key Points

  • Jamison Creek in the Blue Mountains was contaminated by a pesticide, Bifenthrin, in July 2012
  • The pesticide caused a mass crayfish kill and severe, adverse effects on aquatic macroinvertebrates
  • Eighteen months later, the macroinvertebrate community (including crayfish) has recovered well
  • The incident highlights the potential hazards of urban pesticide use and the risks associated with direct stormwater connections between urban areas and natural waterways.
