SECTION 4 Selected Methods for Counting Indicator and
Opportinistic Organisms
Currently, three primary techniques for the routine detection and enumeration of
indicator and opportunistic bacteria currently are used. They are the MPN, MF,
and plate count techniques. Additionally,presence/absence tests for coliform
bacteria have been approved for NPDWR reporting purposes. All methods use
media designd to select for the growth and identification of specific organisms.
Generally, ea h method also includes inhibitors,restrictive temperatures, and/or
limited nutrie is to restrict growth of unwanted species. In this section, a brief
description o'each technique is followed by an overview of some methods in
current use.
Most Probable Number Tests
The MPN tes'uses a specified number of tubes(based on the expected population
in the sample containing a specific medium and sample water. After incubation,
each tube is e amined for growth of the target organism(s). The number of tubes
showing gro h are matched to a statistically determined table of numbers to yield
the most prob'ble number of organisms in the sample.
Table I lists these numbers(at 95% confidence limits) for a sampling series of
10 tubes containing undiluted sample. Usually, 10 tubes are used if the expected
population is •etween 0(zero)and 23, or 15 tubes(five of each dilution in a
dilution serie'i if the expected population is greater than 23.

Table 2 illustr.tes the MPN index for a 15-tube test—five tubes of each of three
dilutions. A d ution series of 1:1 (no)dilution (five tubes), 1:10 dilution (five
tubes),and 1:100 dilution (five tubes)can be used to estimate populations
between<2 ar,d 1600 organisms.The same 15-tube method can be used when the
expected population is greater than 1600 organisms by using a higher series of
three dilutions. (For example, 1:100-, 1:1000-,and 1:10,000-dilution series can be
used to estimate populations from less than 200 to more than 160,000 per
100 mL.)The PN method is preferred when the sample is turbid,when operator
expertise may be limited, or when sufficient data to prove comparable results by
MF technique have not be gathered.
