Survey of the microbiological quality of bottled water.

Three different types of bottled water had counts of psychrophilic bacteria (aerobic colony count at 22 degrees C) ranging from 10(0)-10(4) colony forming unit/1 ml. The most frequent type of bottled water to exceed limits for psychrophilic microorganisms was still table water. The growth of psychrophilic microorganisms of up to 10(4) CFU/ml began over the six month storage period.
