Louisiana (LA) 7-60 Certified Pool Operator Test Review |
Questions & Answers | Latest Update 2026 | Exam Prep |
Graded A+
1. What does the Saturation Index indicate in pool maintenance?
Filtration efficiency
Temperature regulation
Chemical composition
Water balance
2. If a pool has a high TDS level, what action should a Certified Pool Operator
take to improve water quality?
Increase the chemical dosage to balance the TDS.
Ignore the TDS level as it does not affect water quality.
Add more chlorine to the pool to mask the high TDS.
Dilute the pool water by adding fresh water to lower the TDS level.
3. What two minerals are primarily measured by Calcium Hardness in pool
water?
Iron and copper
Chlorine and bromine
Sodium and potassium
Calcium and magnesium
4. Describe the importance of checking the Saturation Index regularly in pool
and spa maintenance.
, The Saturation Index is only important for spas, not pools.
Regularly checking the Saturation Index helps ensure proper water
balance, preventing corrosion and scaling.
Checking the Saturation Index is unnecessary if chlorine levels are
adequate.
The Saturation Index only affects the appearance of the water.
5. What is the recommended level of Total Alkalinity for maintaining pool water?
100 ppm
150 ppm
200 ppm
50 ppm
6. Describe why out-of-range chemical readings can lead to a pool closure by
health inspectors.
Out-of-range chemical readings only affect the pool's appearance.
Out-of-range chemical readings are only a concern for pool
maintenance.
Out-of-range chemical readings indicate unsafe water conditions
that can harm swimmers.
Out-of-range chemical readings are irrelevant to pool safety.
7. Describe what Total Dissolved Solids (TDS) indicates about the quality of
pool water.
TDS indicates the concentration of all dissolved substances in pool
water, which can affect water quality and clarity.
TDS is a measure of the pool's water circulation efficiency.
, TDS refers to the amount of chlorine present in the water.
TDS measures the temperature of the pool water.
8. What substances are measured by Total Alkalinity in pool water?
Calcium and magnesium
Carbonates, bicarbonates, and hydroxides
Chlorine and bromine
pH and temperature
9. Describe the role of muriatic acid in pool maintenance and its effect on pH
levels.
Muriatic acid is only used for cleaning pool surfaces.
Muriatic acid is used to increase chlorine levels in the pool.
Muriatic acid is used to lower the pH levels in pool water, helping to
maintain proper water balance.
Muriatic acid raises the pH levels to prevent corrosion.
10. To adjust the tested Total Alkalinity in the pool to an acceptable level, which
chemical would be most appropriate?
Sodium Hypochlorite
Sodium Carbonate
Sodium Bicarbonate
Sodium Chloride
11. Cyanuric acid (stabilizer) protects free chlorine (FC) against the effects of:
Ultraviolet rays from the sun
