WFD Cycle 1 2015 Deteriorations: Water Body Status Changes in England

2015 water body status changes assessed against a 2009 baseline for England under the Water Framework Directive. The dataset includes statistical confidence and derived certainty metrics for each detected deterioration. It was created by the Environment Agency and is provided in XLSX format.

Use Cases

• Identify water bodies experiencing quality deterioration based on the 2009-2015 comparison.
• Assess the statistical confidence of reported status downgrades.
• Prioritize areas for environmental intervention based on derived certainty scores.

Strengths

• Includes statistical confidence and derived certainty metrics for each deterioration assessment.
• Focuses on a specific regulatory cycle (Cycle 1) and year (2015) for clear temporal scope.
• Geographic scope is explicitly defined as England only.

Limitations

• The dataset has been retired and superseded by another record.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
