Evaluation of Coli-Count Samplers for Possible Use in Standard Counting of Total and Fecal Coliforms in Recreational Waters

摘要

Millipore Coli-Count Samplers were used to enumerate colonies of laboratory cultures of coliform bacteria. The samplers gave significantly lower counts than standard membrane-filter procedures for both total and fecal coliforms. Although the samplers are useful for semiquantitative analysis as indicated by the manufacturer, they are not suitable for standard examinations of recreational waters.
