Abstract:: There is good evidence that a significant amount of gastrointestinal illness is transmitted via drinking water and that a substantial and increasing proportion of this is due to entry of pathogenic micro-organisms into the distribution system through leaks in pipes. The micro-organisms responsible for these infections occur at very low frequency in drinking water so are extremely difficult to detect. However, the entry of material into a water distribution system is likely to produce other changes in the organisms present within the system, either because additional organisms can enter the system or the addition of organic matter from the incoming water allows some organisms to grow. We will use molecular tools to characterise the whole microbial flora present in water samples taken from water distribution systems and identify samples that are markedly different from those collected from near to the water treatment plant and are therefore likely to have been influenced by material that has entered into the pipes from the surrounding soil.
