Water Nitrate
Benchmark Value
Scoring Curve
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 outflow concentration of 0.2 mg/L DIN is therefore a credible and data-driven benchmark for the "best available condition" that a state-of-the-art aquaculture system with integrated bioremediation should achieve in its final discharge.
Dissolved Inorganic Nitrogen (DIN) is the sum of ammonia, nitrite, and nitrate.
A benchmark for the 'best available condition' achievable through state-of-the-art biological nutrient removal.
As direct, published data for best-practice Integrated Multi-Trophic Aquaculture (IMTA) is unavailable, this value serves as a robust, scientifically-defensible proxy based on high-performance sewage polishing wetlands in tropical Australia.
