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.

Based on the most recent data (After Remediation) for Ferrara – ER-site, the site is assessed as: Monitor — consider action. Chemistry: dominant level is Unclassified (0 high-risk, 0 risk, 0 no-risk, 6 unclassified of 6 measurements). Ecotoxicology: dominant category is C (Medium toxicity). The most sensitive organism is Daphnids. Across the recorded phases, ecotoxicity is improving across phases. Recommendation: the site is not clear yet — keep it under active monitoring, compare with the following phases, and verify potential contaminant sources. Biology / supportive methods (provisional): nitrification exceeds ±20% — significant effect on the nitrifying community. These indicators are shown for reference and do not yet affect the overall stance.
