When should lifeguards perform regular water quality tests?

Lifeguards should perform regular water quality tests at the beginning of each opening shift to ensure that the water is safe for swimmers. Conducting these tests consistently at the start of each day helps to monitor essential water parameters such as pH levels, chlorine concentration, and the presence of contaminants. This proactive approach allows for immediate corrective actions to be taken if any issues are detected, thereby minimizing the risk of health problems for patrons.

Testing only upon receiving a complaint or after significant weather events like heavy rain may lead to missed opportunities for addressing potential water quality issues before they affect swimmers. Weekly testing may not capture fluctuations that could occur daily or even hourly, especially in busy facilities or during heavy use. Thus, regular testing at the beginning of each shift is a crucial practice for maintaining a safe swimming environment.
