What you can do with it
Typical work that data of this type supports.
- 01
Hotspots and trends
Find where contamination is high and whether it is getting worse.
Because it has: Dissolved Oxygen
- 02
Compliance checks
Compare samples against drinking water and discharge standards.
- 03
Storage tracking
Follow storage and releases through the season.
Because it has: Lake Sensor Time Series
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Risk maps
Predict contamination where no samples exist, from geology, land use and climate.
- 02
Anomaly alerts
Catch sudden spikes in sensor or lab data automatically.
- 03
Storage from space
Estimate volume from satellite water area and altimetry.
