Groundwater is very important in Estonia.
Groundwater supports nature and agriculture.
Many people drink groundwater.
Scientist Magdaleena Männik invented a new tool.
This tool shows where water needs to be protected.
Water needs protection before it gets polluted.
Polluted water is difficult and expensive to clean.
The new tool helps identify risk areas.
Estonia has old water protection rules.
These rules date back to the 1980s.
The new tool is precise and uses modern methods.
Water does not recognize national borders.
Therefore, cooperation with neighboring countries is important.
Agriculture can damage water.
Fertilizers can pollute water.
The new tool shows where the risk is greater.
Some regions are naturally safe.
In other regions, the risk is higher.
Magdaleena's work helps better understand water protection.
It helps make better decisions.
