The key idea is that HAA5 is the total concentration, in drinking water, of five specific regulated haloacetic acids. Those five are monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid. The chosen wording communicates that concept by describing a sum that includes those five regulated acids. Other phrasings miss the idea of combining the five specific disinfection byproducts into one single measure, so this option best captures what HAA5 represents.
