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 3 benchmarks together — the OptimalRange form drives the primary score, while 2 guard(s) constrain the result.

Evidence & Context
Based on established guidelines and empirical data from reference catchments in the Australian Alps, a reference EC value of < 30 µS/cm is proposed. More specifically, a range reflecting observed natural background levels in minimally disturbed streams, such as 2.9 – 26.5 µS/cm, represents the target for high environmental health.
Water electrical conductivity (EC) in water bodies within the Australian Alpine and Subalpine Complex under best-practice sustainable or regenerative agricultural crop production.
Water electrical conductivity (EC) benchmark representing natural background levels in minimally disturbed alpine and subalpine streams.
The benchmark is an ecologically sound inference supported by robust scientific data from pristine or minimally disturbed alpine catchments and regional water quality guidelines, despite the absence of direct empirical data from agricultural crop production sites in this biome.
