Why doesn't chlorine kill these RWI germs?
Chlorine
in swimming pools does kill the germs that may make people sick, but
it takes time. Chlorine in properly disinfected pools kills most germs
that can cause RWIs in less than an hour. Chlorine takes longer to
kill some germs such as Crypto, which
can survive for days in even a properly disinfected pool. This means
that without your help, illness can spread even in well-maintained
pools. Healthy swimming behaviors are needed to protect you and your family from RWIs and will help stop germs from getting in the pool.
