If a 45,000-gallon indoor pool has a total available chlorine of 2.2 ppm and free available chlorine of 1.4 ppm, what is the level of chloramines?

  1. 0.4 ppm

  2. 0.6 ppm

  3. 0.8 ppm

  4. 1.0 ppm

The correct answer is: 0.8 ppm

The level of chloramines is not directly provided in this question, but it can be calculated by subtracting the free available chlorine (FAC) from the total available chlorine (TAC). In this case, the difference between the TAC and FAC is 0.8 ppm (2.2 ppm - 1.4 ppm), meaning that the level of chloramines is 0.8 ppm. This is because the total available chlorine includes both free available chlorine and chloramines, so by subtracting the FAC, we are left with the amount of chloramines present in the pool. The other options do not accurately reflect the calculated level of chloramines and therefore, are incorrect.
