What does Clostridium perfringens in water mean in practice?
Its spores persist longer than many vegetative bacteria and may reveal past or intermittent source contamination.
When does it matter?
A positive result requires assessment of the source, filtration and disinfection rather than only a one-off dose increase.
Which solutions are related to it?
Protect the source, reduce turbidity, apply effective filtration and disinfection and repeat the test.
