Full Description

In developing a methodology to assess microbial based risk to consumers from recycled water, a technique to enumerate pathogens should be employed. In drinking water applications the typical indicator organisms tested for are total and fecal coliform. While these are good indicators of contamination, they are relatively large in size (0.1-10 microns). The Information Collection Rule (ICR) has recommended the use of MS-2 bacteriophage as an indicator organism as it is similar in size and shape to human enteric viruses, but is not a human pathogen. This paper analyzes a membrane filtration method for the concentration and enumeration of indigenous coliphage as a way to monitor virus removal through low and high pressure membrane systems. Includes 8 references, tables, figures, appendix.
