What does the smell of water mean in practice?
The rating depends on the temperature and route of collection; the smell in warm water may have a different source than in cold water.
When does it matter?
The lack of odor does not confirm safety, and the intense odor does not clearly identify a specific compound.
Which solutions are related to it?
Samples from the source and collection points are compared, and the tests and technology are selected to suit the nature and location of the odor.
