Water Nitrate

AUS-TDG-CON-WNI General High confidence

Benchmark Value

0.15 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

NOʒ-N (mg/L) ... 0.15 ... ANZECC 2000 Guidelines are for South West Australia from Table 3.3.6, Volume 1, Chapter 3 National Water Quality Management Strategy

Metric Definition:

Concentration of dissolved nitrate-nitrogen (NO3-N) in milligrams per litre, representing the regional default trigger value for South-west Australia.

Benchmark Definition:

Provides the regional default reference trigger value for physical and chemical stressors in river systems of South-west Australia.

Justification:

Provides the regional default reference trigger value for physical and chemical stressors in river systems of South-west Australia.
