Water quality monitoring

What problem is Fondation Rivières trying to solve?

The quality of a watercourse can vary depending on the weather, the behaviour of its tributaries and many nearby human activities. This makes it difficult to ensure that swimming or boating in a watercourse is always safe.

Water quality is usually measured by the amount of bacteria Escherichia coli (E. coli) present. At low concentrations, this bacteria is not dangerous for health, but its presence in large quantities is an indicator of the presence of other bacteria which could cause gastrointestinal illnesses, among others.

It takes between 24 and 72 hours to know the quantity of E. coli with traditional bacteriological analysis techniques, which is hardly useful in waterways where contamination peaks are frequent, but short-lived. This explains why beaches can be closed for several days in a row while awaiting results.
