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.
Supportive methods evaluation
| Sample | Type | Method (phase) | Diversity (H′ / 1−D) | Nitrification | Respiration | Conformity |

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.

|---|---|---|---|---|---|---|
| Untreated Metfilter Effluent | water | Before Remediation | — | — | — | — |
| Electro-Fenton + Bioreactor treatment | water | After 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 |
|---|---|---|---|---|---|
| Untreated Metfilter Effluent | water | Before Remediation | 8.4% | Within ±20% | Conforming |
| Electro-Fenton + Bioreactor treatment | water | After Remediation | -11.6% | Within ±20% | Conforming |
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 Alcalá de Henares – Municipal WW, the site is assessed as: Site OK — routine monitoring. Chemistry: no classified measurements available for this phase. Ecotoxicology: dominant category is B (Low toxicity). The most sensitive organism is Lettuce aquatic. Across the recorded phases, ecotoxicity is improving across phases. Recommendation: the site is within acceptable limits — continue with routine monitoring to confirm the favourable condition remains stable. Biology / supportive methods (provisional): biodiversity rising across phases. These indicators are shown for reference and do not yet affect the overall stance.
