Water Electrical Conductivity (EC)
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 11 benchmarks together — the OptimalRange form drives the primary score, while 10 guard(s) constrain the result.
Evidence & Context
Any sustained elevation of EC above the natural background range (i.e., consistently >30 µS/cm) should be considered a trigger for investigation and a potential indicator of diminishing environmental health.
Water EC level above which ecological harm begins in Australian alpine and subalpine aquatic ecosystems.
This benchmark defines the minimum water electrical conductivity level in Australian alpine streams above which ecological harm is likely, signaling the need for investigation.
Based on evidence of ecological harm to sensitive alpine macroinvertebrates at sustained EC levels above natural background.
