Scoped to one remediation method. Before = baseline samples matching the method's sample type; a phase the method doesn't have shows as “no data”.

Each column is one sampling date; a cell shows the worst result recorded across that date's samples. A phase with no samples for the selected method shows as “—”. Supportive methods are shown for reference and do not yet move the overall stance.

58.1% Exceeds ±20% — significant effect on the nitrifying community

No samples recorded for this stage.
Biodiversity is read as a trend — rising Shannon / Simpson from the before stage onward indicates recovery. Expected levels per phase are in admin → Biology phase profiles.

| VZ1 | water | Before Remediation | — | — | — | — |
| VZ2 | water | Before Remediation | — | — | — | — |
| VZ3 | water | Before Remediation | — | — | — | — |
QR ≤ 0.5 acceptable. QR > 0.5 → check AHB: ≥ 10³ CFU/g = bioremediation not suitable (strongly inhibited); < 10³ = not suitable without microbial augmentation (bioaugmentation, repeat measurements, assess inhibition).
| Sample | Type | Phase | Inhibition / stimulation | Evaluation | Conformity |
|---|---|---|---|---|---|
| VZ1 | water | Before Remediation | 8.3% | Within ±20% | Conforming |
| VZ2 | water | Before Remediation | 58.1% | Exceeds ±20% — significant effect on the nitrifying community | Nonconforming |
| VZ3 | water | Before Remediation | 56.4% | Exceeds ±20% — significant effect on the nitrifying community | Nonconforming |
The inhibition or stimulation of nitrification must not exceed ±20%. Values beyond this indicate a significant effect of the sample on the nitrifying microbial community.

Conclusion
Auto-generated draftBased on the most recent data (After Remediation) for Ferrara – ER-site, the site is assessed as: Remediation recommended. Chemistry: no classified measurements available for this phase. Ecotoxicology: dominant category is E (Very high toxicity). The most sensitive organism is Algae. Across the recorded phases, ecotoxicity is stable across phases. Recommendation: the contamination level still warrants action — continue or adjust the remediation strategy, identify the main contaminant, and re-sample to confirm a downward trend. Biology / supportive methods (provisional): values recorded. These indicators are shown for reference and do not yet affect the overall stance.
