"Number concentration" means the number of particles or other specified objects per unit volume. In this context, it represents the number of colony-forming units (CFU) of bacteria belonging to the species Clostridium perfringens. Because this bacteria is a normal component of the human intestinal tract, its presence in samples of sea water can be used as a tracer of sewage contamination. As such, it is commonly measured in beach water quality monitoring programs.
