What term describes the measurement for the overall effectiveness of sanitation chemicals in water?

The term that describes the measurement for the overall effectiveness of sanitation chemicals in water is total chlorine. This measurement encompasses both the free chlorine and combined chlorine levels. Free chlorine refers to the amount of chlorine available to sanitize and disinfect the water, while combined chlorine consists of chlorine that has reacted with contaminants and is no longer effective as a sanitizer.

Total chlorine is crucial because it provides a comprehensive assessment of the chlorine present in the pool water, allowing pool operators to understand the total amount of disinfectant available for maintaining water quality. By knowing the total chlorine level, operators can make informed decisions regarding chlorine addition and overall pool sanitation practices, ensuring that the water remains safe and clean for swimmers.

The distinction of total chlorine is important in maintaining proper quality in commercial pools, where sanitation is paramount for health and safety.
