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.

Total Coliform Rule Brain Teaser
Journal AWWA, 2009This brain teaser deals with a hypothetical situation where a small public water system (one that is normally required to only assay one routine total coliform sample during a month) will have to assay five samples in one month's time. The five samples can be either one routine and four repeat samples or five routine samples and no repeats.

The Analysis of Fecal Coliforms and Coliform Total in Wells Water at the Tourism Area of Sanur
Indian Journal of Public Health Research & Development, 2018Sanur is a tourism area that located in the south of Denpasar, which includes the village of Sanur, Sanur Kaja, Sanur Kauh, and Renon, with clean water wells facilities as many as 3174 wells. Utilization of water wells in this region 87% of the total existing wells.

Reconsidering the Total Coliform Rule
Journal AWWA, 2000Amendments to the 1996 Safe Drinking Water Act (SDWA) require the US Environmental Protection Agency (USEPA) to review and revise as needed existing National Primary Drinking Water Regulations at least every six years. This article discusses the Total Coliform Rule, which is among the first regulations to be reviewed for possible revision.

New Regulations for Total Coliforms
Journal AWWA, 1990Articles in this section of the Journal are dedicated to providing current information about legislative and regulatory developments pertinent to the drinking water industry. They address needs and concerns of water utilities from a practical standpoint; they are not intended to reflect official positions or policies of AWWA. Frederick W. Pontius, AWWA

Prediction of Salmonella in seawater by total and faecal coliforms and Enterococci
Marine Pollution Bulletin, 2009The power of total coliforms (TC), faecal coliforms (FC) and Enterococci to predict the presence of Salmonella in seawater was investigated. Indicator cut-off values with the most satisfactory combination of sensitivity and specificity in predicting Salmonella presence were 1,000 CFU 100ml(-1)TC, 200 CFU 100ml(-1)FC, 500 CFU 100ml(-1) Enterococci.

Total Coliform Survival Characteristics in Frozen Soils
Journal of Environmental Engineering, 2007Survival characteristics of total coliform bacteria in soil samples, with different moisture contents (24–49%) and at different temperatures (from −28 to 20°C ), were studied. The study showed that a significant fraction of coliform bacteria survive for more than six months in soil at subfreezing temperatures.

Prepare for the Revised Total Coliform Rule
Opflow, 2014Public health is protected when system operators can respond quickly to correct situations in which coliform bacteria occur in drinking water. A key to success is being aware of where and how such events can occur.

Although the total coliform bacterial count has its shortcomings, it is our best indicator of the health hazards associated with drinking water that we have today. Some of these defects can be corrected by additional bacterial tests to determine interference or identify nonconliform lactose fermenting organisms.

Building an Improved Total Coliform Rule
Journal AWWA, 2010This article discusses a September 2008 agreement in principle (AIP) recommending a number of key changes to the Total Coliform Rule (TCR) that were agreed upon by the TCR Distribution System Federal Advisory Committee (TCRDSAC).
