If a pool has a total available chlorine of 2.2 and a free available chlorine of 1.4, what is the level of chloramines?

To determine the level of chloramines in a pool, you subtract the free available chlorine from the total available chlorine. Total available chlorine is the sum of free available chlorine and combined chlorine (which includes chloramines).

In this scenario, the total available chlorine is 2.2, and the free available chlorine is 1.4. By performing the calculation:

Total Available Chlorine - Free Available Chlorine = Combined Chlorine (Chloramines)

So, 2.2 - 1.4 equals 0.8. This indicates that the level of chloramines in the pool is 0.8.

This understanding highlights the importance of monitoring both total and free chlorine levels to ensure effective sanitation in your swimming pool, as the presence of chloramines can affect water quality and swimmer comfort. High levels of chloramines often indicate that additional treatment may be necessary to maintain water clarity and safety.
