ENTEROBACTERIACEAE-- TO A FARMER THIS IS A BUCKET OF PATHOGENIC COLIFORM BACTERIA
EPA allows 5% of required monthly drinking water samples to be contaminated with gram negative coliform bacteria. The
test takes 24 hours to preform. For people with improperly functioning immune systems it may be playing a game of
Russian Roulette. See the District of Columbia (DC) Test graph for the past year -- below the table of gram negative
Coliform is the name of a test -- Total coliform (including E. coli) is the working name for a small class of gram-negative
Enterobacteriacea that ferment lactose to produce gas and acid when incubated at 35 degree C for 24-48 hours.
Fecal coliform is the heat inhibited thermotolerant form of E. coli bacteria that continue to ferment some lactose to
produce some gas and acid when incubated at 44.5 degree C for only 24 hours.
Coliforms means coli-like-forms "similar to E. coli"
Fecal coliforms are thermotolerant coli-like-forms "similar to E. coli" defined by the time and temperature of the test.
Similar coli-like-forms are Citrobacter, Enterobacter, and Klebsiella.
EPA claims sludge is safe because it does not test for any bacteria listed as: 1) Infectious characteristics (RCRA); 2) disease causing
agents (CWA - CERCLA); and 3) Etiologic Agents (CDC) The Public Health Security and Bioterrorism Preparedness and Response
Act of 2002, (UDSDA 9CFR 121 & 7 CFR 331) and hazardous waste rules Part 261.

The terms coliform and fecal coliform are confusing. Coliform is a test for a class of bacteria that ferment lactose at normal body
temperature in 48 hours. Fecal coliform are E. coli bacteria that ferment lactose to produce gas (indole) and acid at an elevated
temperature well past the point the normal body has died. According to EPA there may only be two bacteria classified as a fecal

Mark Meckes, epa.gov writes: "For example, most strains of Escherichia coli will ferment lactose under the elevated temperature
test for fecal coliform and therefore will meet the definition of "fecal coliform." Similarly, some strains of Klebsiella will also ferment
lactose under these same test conditions and will meet the definition of "fecal coliform".
EPA and other experts claim the following list of coliform bacteria do not cause death or disease? They actually cause
more diseases than listed here.

Coliform Content Report
DC WASA collects over 200 samples monthly throughout the District and analyzes for coliform bacteria. The test indicates whether any
coliform are present in the sample. Most coliform bacteria are not harmful to ingest (your intestines contain coliform that aid in
digestion). EPA requires testing for coliforms because they can indicate the potential presence of more harmful microorganisms. If DC
WASA detects coliform, vigorous follow-up sampling and testing is immediately conducted to ensure no harmful microorganisms are
EPA allows up to five percent of the samples collected in a month to be positive for total coliform. The graph below shows the percent
of monthly samples testing positive for total coliform over the past year.
As shown in the graph, DC WASA consistently is below EPA's requirements regarding bacteria levels in the water. However, immune
compromised people are at a greater risk in developing illness. WASA encourages immune compromised individuals to consult with
their doctor regarding extra precautions to avoid infection.
