What is the primary function of performing regular chlorine testing in pool water?

The primary function of performing regular chlorine testing in pool water is to maintain proper sanitizer levels. Chlorine serves as a disinfectant that kills bacteria, algae, and other harmful pathogens in the water, ensuring the safety and cleanliness of the pool for swimmers. By regularly testing the chlorine levels, pool operators can confirm that the concentration is within the ideal range, which is crucial for effective sanitation.

Maintaining proper sanitizer levels helps to prevent outbreaks of waterborne illnesses and ensures that the water remains clear and inviting. If chlorine levels are too low, the pool may become a breeding ground for harmful microorganisms. Conversely, if levels are too high, it can lead to irritation of the skin and eyes for swimmers. Thus, regular assessments allow for timely adjustments, ensuring a balanced and safe swimming environment.
