At 22C, the TVC indicates the variety of live microorganisms per ml of water at ambient temperature level, meaning the count will primarily be made up of safe microorganisms.

Samples drawn from cooling tower systems, on the other hand, ought to be nurtured at 30C according to ACo, P L8, HSG 274 Component 1.
