Water Turbidity
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 6 benchmarks together — the OptimalRange form drives the primary score, while 5 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
The optimal range is considered < 5 NTU, reflecting the clear water conditions of natural refuge pools between rainfall events.
Water turbidity as a measure of water clarity, quantifying the degree to which light is scattered by suspended particles such as silt, clay, organic matter, and microorganisms.
This benchmark defines the optimal water turbidity range indicating high water quality and ecological condition in urban and developed areas of the Arid Karstic Woodlands & Shrublands biome.
The optimal range aligns with the lower end of ANZECC guidelines for high conservation value ecosystems and aesthetic drinking water standards.
