The Total Dissolved Solids (TDS) of the Swimming pool should not exceed
- A500 mg/L
- B1500 mg/LCorrect
- C750 mg/L
- D2000 mg/L
Solution
Concept
Maximum total dissolved solids in swimming pools
Formula
NONE
Step-by-step solution
1. Total Dissolved Solids (TDS) measures the combined total of all organic and inorganic substances dissolved in water. 2. For swimming pools, high TDS levels cause water clarity issues, scaling, and corrosion of fixtures. 3. Standard swimming pool water quality standards specify that TDS should not exceed 1500 mg/L. Answer: B
Explanation
Standard water quality standards for swimming pools mandate that the total dissolved solids level should not exceed 1500 mg/L to ensure swimmer comfort and safety. High concentrations of dissolved solids above this limit can lead to murky water, reduced sanitizer efficiency, and severe corrosion or scaling on pool equipment. Maintaining TDS within this limit helps preserve water clarity and chemical balance.
Why the other options are wrong
A) 500 mg/L is the desirable limit for drinking water, not the swimming pool threshold. C) 750 mg/L is below the standard upper limit for swimming pool water. D) 2000 mg/L exceeds the acceptable maximum threshold for swimming pool TDS.
Shortcut
The standard upper limit for Total Dissolved Solids in swimming pools is 1500 mg/L.
Common mistake
Confusing the swimming pool TDS limit of 1500 mg/L with the standard drinking water limit of 500 mg/L.
Correct answer: B) 1500 mg/L
