REGROWTH OF FECAL COLIFORMS IN CLASS A BIOSOLIDS
Proceedings of the Water Environment Federation, 2004Eight types of Class A biosolids were tested for fecal coliform (FC) reactivation and/or regrowth at 20, 35, and 50?C for 21 days. Growth of FC did not occur at 20 or 50?C, but it was observed in two samples incubated at 35?C after a lag period of 48 hours.

Significance of fecal coliform and fecal streptococcus in water pollution monitoring
Acta Academiae Medicinae Wuhan, 1982The experimental results showed that the fecal coliform (FC) to fecal streptococcus (FS) ratio (FC/FS) in the human feces and in warm-blooded animal feces were rather different. FC/FS ratio in the human feces was greater than 7.0, and in warm-blooded animal feces was less than 1.0.

Coliform Group and Fecal Coliform Organisms as Indicators of Pollution in Drinking Water
Journal AWWA, 1960The presence of any type of coliform organism in treated drinking water suggests either inadequate treatment or access of undesirable materials to the water after treatment. Although there are some differences between strain and subgroup organisms with regard to survival under natural conditions and resistance to chlorination, in general all the ...

Surface streaking and fecal coliform levels
Canadian Journal of Civil Engineering, 1984The measurement of the dilution and die-off of fecal coliforms in high velocity, wind-generated surface currents is discussed. The dispersion in the streaks is similar to that found in oil slicks. It was found that the high velocities and slower growth rate of the dispersion in the streaks resulted in fecal coliform levels about four times higher than
