Water Nitrate

AUS-TGP-FOR-WNI General Moderate confidence

Benchmark Value

0.19 mg/L
Direction: Lower is desirable ↓
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

This benchmark represents the 80th percentile trigger value for nitrate-nitrogen (NO3−​-N) in upland rivers, derived using the ANZECC (2000) methodology.

Metric Definition:

Nitrate-nitrogen (NO3−​-N) concentration in water

Benchmark Definition:

This benchmark indicates the upper limit of nitrate-nitrogen concentration in water for maintaining high ecological health in Australia's Temperate Grassy Woodlands & Plains under sustainable production forestry. Values above this suggest a decline from the reference condition.

Justification:

The benchmark is derived from the ANZECC (2000) guidelines and regional application for Tasmanian upland rivers, representing a scientifically defensible value for best available condition in the biome.

Lower critical threshold is not relevant; the benchmark is the upper limit for high ecological health; toxicity thresholds are much higher; optimal range is from lowest measurable to this benchmark.
