Conclusion of experiment:

This project has been funded with support from the European Commission. This publication/communication reflects the views only of the author, and the Commission cannot be held responsible for any use which may be made of the information contained therein.

1. 1. Nitrates' quantity in all investigated water pools is quite similar.

2. The investigated water pools of regional park's water is not suitable to drink.In this water nitrates quantity is over the rate of suitable to drink water's nitrates' quantity.(0-10 ppm).

The experiment is made by class 3 d
