No, mussels don't shut off Warsaw's water supply if they sense toxins — but they help monitor it

Summary

Nutrition label

87% Informative

Warsaw Waterworks uses swollen river mussels ( Unio tumidus), not clams, for biomonitoring.

Mussels are highly sensitive to water pollution and help monitor water quality in the Vistula River and Lake Zegrzyski .

The alarm is triggered only if six out of eight mussels stay closed for more than four minutes and the average amount of shell closure exceeds 25% . Mussels do not directly shut off the water supply, but rather trigger an alert for further testing.

" Fat Kathy " is a documentary by Julia Pelka about the role of mussels in Warsaw 's water monitoring system.

Fat Kathy is the name of a key water intake facility on the Vistula River .

In the past, we have looked at claims that one adult oyster can filter more than 50 gallons of water in 24 hours .
