This table compiles structured metadata for each recorded environmental impact event. The dataset integrates quantitative measures (e.g., pollutant volumes, affected surface areas), categorical variables (e.g., event type, containment and remediation status), and procedural information (e.g., enforcement actions, resolution codes, timelines). Each row represents a unique impact, harmonized across official enforcement records (OEFA) and participatory monitoring sources. Geographic coordinates are standardized, and duplicate entries were removed through cross-validation. The table includes identifiers, source reliability checks, temporal markers, spatial descriptors, and compliance outcomes, enabling reproducibility and comparative analysis of environmental incidents and associated accountability processes
