SWIMMING POOL OPERATOR
CERTIFICATION 2025 UPDATED ACTUAL
EXAM WITH CORRECT SOLUTIONS.
First step of fecal accident procedure - correct answer- Direct
all bathers to leave the pool. All affected waters must be closed
to swimming until proper procedures for contamination have
been completed
Second step of fecal accident procedure - correct answer-
Manually remove as much of the material as possible using a
net or scoop and dispose of it in a sanitary manner. Clean and
disinfect the scoop or net. After cleaning leave the net or scoop
immersed in the pool during this infection. Vacuuming the stool
is not allowed.
Establish a fecal accident log documenting....? - correct
answer- (1) the date and time of the event
(2) if the accident is a result of a form stools or diarrhea
(3) The free available chlorine concentration at the time or
observation of the event and before opening the public pool
(4) The pH
(5) The procedures followed to respond to the fecal accident
including the process used to increase free chlorine residual if
necessary
(6) The contact time

Procedures for form stool that is solid and not liquid - correct
answer- Raise the free available chlorine level to 2 ppm and
ensure that the pH is between 7.2 and 7.5
Maintain the chlorine concentration for at least 25 minutes.
Ensure this concentration is found throughout all waters by
sampling at least three widely spaced locations away from
return outlets
Procedures for diarrhea liquid or non-form stools - correct
answer- Raise the free available chlorine level two 20 ppm and
ensure that the pH is between 7.2 and 7.5
Maintain the chlorine concentration and pH for eight hours
while ensuring that the filtration system is operating. Backwash
the filter thoroughly discharging the effluent directly to waste.
Where appropriate replace the filter media
Bathers may be allowed into pool after chlorine concentration
has been returned to normal operating ranges
Acid demand - correct answer- The amount of acid required to
reduce pH and alkalinity to the correct range
Algae - correct answer- Microscopic plant like organisms that
grow in water do to warm temperatures and in adequate

sanitizer. Algae can be green blue green black or yellow green
(mustard).
Alkalinity - correct answer- A measure of the ability of pool
water to resist changes in pH. Buffering capacity of water.
Balanced water - correct answer- The correct ratio of hardness,
alkalinity, temperature, dissolved solids, and pH that prevent
pool water from being either corrosive or scale forming
Bromine - correct answer- A chemical element that exists as a
liquid in its elemental form or as part of a chemical compound
that is an oxidant and a biocidal agent used to disinfect pool,
spa and hot tub water.
Bromamine - correct answer- Bromine-ammonia compounds
formed when the bromine in the water combines with ammonia,
nitrogen or swimmer or bather waste. Unlike Chloramines they
do not smell or irritate the body. They are active sanitizers.
Calcium hardness - correct answer- The amount of dissolved
calcium in the pool. High levels promote scale and cloudy
water. Low levels promote corrosion of the pool or spa
equipment.
