Water Research, 2003
In July 1999, California's ocean recreational bacterial water quality standards were changed from a total coliform (TC) test to a standard requiring testing for all three bacterial indicators: TC, fecal coliforms (FC), and enterococci (EC). To compare the relationship between the bacterial indicators, and the effect that changing the standards would ...

Nematodes as a source of total coliforms in a distribution system
Canadian Journal of Microbiology, 2007In a distribution system of a large North American city, recurring total coliforms and atypical coliforms were detected at the exit (distribution pumps) of a storage reservoir. The presence of total coliforms and atypical coliforms was noted when the pumps were in operation and the water temperature was higher than 18 °C.

USEPA Approves New Method for Total Coliform Testing
Opflow, 1992This article describes Colilert, a quick and easy way to test for coliforms. Other similar tests, such as Coliquick and Colisure, perform the same function but at the time this article was printed, were still awaiting final USEPA approval.

Statistical limitations in the usefulness of total coliform data
Journal AWWA, 2009Most water systems— rates of coliform‐positive samples are well below the 5% trigger for the monthly maximum contaminant level (MCL) set by the Total Coliform Rule (TCR). This study reviewed results of 540,357 samples collected from 15 systems and represented more than 12 years of sampling.

Investigation of Total Coliform Bacteria in Aquarium Water
2014Bu çalışmada, 5 akvaryum hazırlanmış, birer hafta arayla 3 (3x5) seri deney yapılarak, toplam canlı koliform bakteri sayısı tespit edilmiştir. Akvaryumlarda 2'şer adet olmak üzere Tinca tinca L., 1758 ve Alburnus escherichi Steindachner, 1987 kullanılmıştır. Balıklar Mogan Gölü\'nden avlanarak temin edilmiştir.
