                                               Comparison
                      Fecal Coliform vs Salmonella - E. coli - Strep

Fecal coliform are thermotolerant (heat resistant) inhibited forms of E. coli
The difference between sludge disease organism in the  fecal coliform test at 112.1 degF and sludge
biosolids disease organisms at normal temperature is like comparing apples and oranges.

Sample 1 & 2 is a direct result of runoff from the Kansas City sludge site 1 year after sludge was applied.
Sample 4 was taken from sludged site to verify that this was human bacteria

In this apple and orange comparison fecal coliform testing is at 112.1 deg F while salmonella, E. coli and
staph were tested at 95 deg F. Since this was a one time test it was reported as colonies rather than most
probable number (MPN) as EPA does.

Sample 1: Fecal coliform    -- 90 colonies per gram
          Salmonella         -- >8,000 colonies per gram

Sample 2: Fecal coliform   -- 30 colonies per gram
          E. coli                 -- >8,000 colonies per gram

Sample 4: Fecal coliform    -- 500 colonies per gram
          Strep                   -- 1,000 colonies per gram

Sample 3: Fecal coliform    -- 6,500 colonies per gram -- area that received sludge once, 6 years earlier.
