The heterotrophic plate count (HPC), formerly known as the standard plate count, is a useful tool for enumerating bacteria in potable water. The document briefly reviews the development of the heterotrophic bacterial plate count for use in water quality measurements in the United States. Methodology considerations in the selection of the HPC procedure to be used include medium (high or low nutrient), incubation time, incubation temperature, and method (pour plate, spread plate or membrane filter). Applications of HPC monitoring include evaluation of treatment processes, storage and distribution water quality changes, biofilm development, growth of bacteria on construction materials and microbial corrosion.
