Evaluating Environmental Quality Standards (EQS) requires more than raw data — it requires transparent calculations, validation mechanisms, and intuitive visualization.
For Brussels Environment, I developed an innovative Power BI system to calculate and monitor chemical pollution parameters in surface water, representing a first of its kind in Belgium.
The Challenge
Surface water datasets:
• Come from multiple sources
• Require complex regulatory calculations
• Must detect errors and inconsistencies
• Need to be interpretable by both scientists and decision-makers
The Solution
I designed a Power BI solution that:
• Calculates minimum, maximum, and annual average concentrations
• Evaluates EQS compliance automatically
• Computes inflow/outflow percentages, BCR contributions, and BCR load
• Detects inconsistencies across databases
• Consolidates heterogeneous data into a single analytical model
Interactive dashboards provide a holistic and transparent view of surface water quality.
Impact
This system:
• Standardized EQS calculations
• Improved error detection and data consistency
• Enhanced regulatory transparency
• Supported evidence-based environmental policy decisions
Power BI became not just a visualization tool, but a regulatory-grade analytical system.
