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”.
Overall assessment
Remediation method: Enhanced anaerobic in situ biodegradation (PZSEC 162)

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.

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.
