This slide presentation outlines a study with the objectives of:
determining the capabilities of each product to
detect total coliform and E. coli in three
chemically diverse Wisconsin groundwaters;
determining the ability of each product to
accurately quantify the number of total coliforms
and E. coli in Wisconsin groundwaters;
determining the ability of each test to suppress
Aeromonas spp.; and,
determine the unit cost per test. Chemical analysis was conducted each
time a collection was made from each site, and
analysis was done for alkalinity, pH, hardness,
conductivity and soluble iron content. Chemical characteristics of the
groundwater sampling sites are given. Elements of the project design are outlined and include: each site was sampled twice,
once for the total coliform detection objectives and
once for Aeromonas spp. suppression experiments;
samples were dispensed and spiked with five total
coliforms separately at two different levels of
contamination, and each was spiked in triplicate for the total
coliform objectives; and,
the Aeromonas spp. objectives consisted of
dispensing 100mL samples and spiking with six different
contamination levels of two different strains of
Aeromonas spp. in triplicate. Results indicated that:
some methods were unable to detect certain
species of total coliform from groundwater
sources;
major differences were seen in the ability of
each test to quantify amounts of total coliform
and E. coli; and,
vast dissimilarities were seen between methods
and strains to suppress Aeromonas spp. The presentation goes on to outline these discussion points:
some methods were unable to detect certain
species of total coliform in Wisconsin
groundwaters;
major differences were seen in the ability of
each test to quantify amounts of total coliform
and E. coli; and,
vast dissimilarities were seen between methods
and strains to suppress Aeromonas spp.. Includes tables, figures.
