Why do the membrane filtration and the colilert IDEXX technique for measuring fecal coliforms in waste water produce discrepant results?

The membrane filter / agar plates produce colonies from bacteria that can grow on the agar you are using (not all fecal coliforms can). The Colilert will turn color if the bacteria have the enzyme to metabolize substrates in the Colilert (not all do). If all fecal coliform bacteria could grow on the agar and all fecal Coliforms had the right enzymes you'd get the same numbers.
