Point-of-use water treatment devices were investigated for types of organisms that may colonize these filters, the magnitude of microbial post colonization release in the product water during daily use or after periods of non use, and the impact of tap waters of marginal bacteriological quality on the quality of product water. Bacterial colonization relates to the bacterial flora of the drinking water supply, water temperature, ambient air temperature in under-the-sink installations of carbon filters and length of service for a given carbon cartridge. Treatment device designs that used carbon impregnated paper filters were undesirable because of more extensive bacterial colonization and release of organisms in the product water. Static water conditions also favor increased bacterial release in the first water released after periods of non use.
