Monitoring Environmental Quality Standards with Power BI
A Pioneering EQS Dashboard for Surface Water in Belgium

Evaluating Environmental Quality Standards (EQS) requires more than raw data — it needs 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
- 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.
