At this point, is it reasonable to assume then that due to the non-selective nature of TVC analysis, coupled with the delineation between environmental and what may be contaminants of human importance, TVC tests may be useful indicators for system safety? Unfortunately, research suggests a poor correlation between the organisms recovered from a TVC test and a selective test used for the identification of pathogens in human health.
We should not lose sight of the fact that water utility companies provide mains water in fit state to consume, as such why would we routinely sample mains cold water.

In all cases the value on monitoring is to establish data which characterises a water supply in terms of seasonal and longer term changes. Drinking water supplies derived from surface waters tend to support higher numbers of heterotrophic bacteria than those derived from ground water sources.
