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 diseases.
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 coliform.
In a message dated 7/16/2007 12:53:54 P.M. Pacific Daylight Time, 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.
A Few Coliform and Fecal Coliform Bacteria and Diseases they cause
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 present.
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.
Total Coliform Results June 2008 - June 2009 -- Gram negative bacteria that are heat tolerant at 44.5 degree C are coliform. They make up about 5% of all gram negative bacteria. Gram positive and other types of pathogens do not show in test.
