High total nitrogen and denitrification anomalies

Use this when high total nitrogen and denitrification anomalies is observed but the cause remains unclear. The diagnostic checks measurement and sampling, operating changes, issue location, and key evidence before suggesting likely causes and the next useful check.

You do not need every data point before you begin

The system asks one discriminating question at a time and updates the candidate causes on the right. Answer from current facts; choose unknown or defer a question when the evidence is not available.

  1. 1

    Confirm the issue

    Check whether the symptom is reproducible and whether the measurement or observation is reliable.

  2. 2

    Narrow the causes

    Continue through operating changes, issue location, and available inspection results.

  3. 3

    Read the live result

    Candidate causes, support, counter-evidence, conflicts, and next actions update as you answer.

Phase 1 · Data validity

Is the TN anomaly confirmed by applicable methods, lab QC, and independent re-sampling?

The system asks the question most useful for separating possible causes. Unknown or deferred items are not treated as the opposite conclusion.
