1. 1. You operate a 120,000-gallon pool, and upon performing your
hourly chemical tests you observe the following readings: Total
Available Chlorine reading is 1.6 free available chlorine reading is 1.5
pH is 7.4 Your supervising lifeguard has just informed you that you
have had a fecal incident occur; a solid stool has been discharged
into the pool. According to the Centers for Disease
Control, as the CPO,
you should do the following:: clear the pool and raise the free chlorine to 2 ppm

raise the free
chlorine to 5 ppm, how much sodium hypochlorite
would be needed to raise
the free chlorine in the pool in question #1

manager informs you that he is receiving complaints about a strong
chlorine odor in the pool area, and several members have complained
of eye irritation. The most
likely cause of these complaints is:: high levels of
chloramines in the pool
