“…Most of the regrowth problems seem to relate to biofilms, since opportunistic pathogens like L. pneumophila are known to multiply in biofilms, 37 animal vertebrates graze (in)directly on biofilms, 6,7 and microbial induced corrosion is caused by growth of certain bacteria (e.g. sulphate reducing bacteria) in biofilms.…”

The objective of our study was to explore microbiological parameters that are suitable as indicators for regrowth in distribution systems that receive unchlorinated drinking water in the Netherlands. Treated water and distributed water at two locations in the distribution system of 28 treatment plants were analyzed for a range of biological parameters. The results demonstrated that Aeromonas, HPCs, and Mycobacterium were significantly (more often) higher and ATP was significantly (more often) lower in the distributed water than in the treated water, whereas cell numbers remained stable during distribution. Average fungal 18S rRNA gene copies did not differ significantly between the treated and the distributed water, but fungal numbers were significantly more often higher in the distributed water than in the corresponding treated water. These results demonstrate that the distribution system has a clear effect on HPCs, Aeromonas, Mycobacterium, ATP and, to a lesser extent, on fungi in drinking water, but not on cell numbers. Furthermore, we noticed that ATP in the treated water is a better predictor for the regrowth level in the distribution system than total, membrane-intact or HNA cell numbers. In contrast to previous studies, we conclude that ATP and cell numbers seem to be poor indicators for regrowth in the drinking water environment, whereas HPCs, Aeromonas, Mycobacterium and, to a lesser extent, fungi appear to be more reliable indicators to monitor regrowth.

“…Along with the sessile and free swimming bacteriafeeding protozoans, small metazoans appear in these ecosytems, e.g. rotifers, worms (Annelida, Nematoda and Platyhelminthes) and small crustaceans (Cladocera, Copepoda, Ostracoda and Isopoda) (Van Lieverloo et al, 2012). Since metazoans graze the biofilms in the pipes, the content of their guts will reflect the respective biofilm biocenosis.…”

“…Invertebrates visible to the naked eye, for example the arthropod Asellus aquaticus, may cause consumers' complaints about the quality of drinking water and block water meters (Smalls and Greaves 1968; Levy et al 1986;van Lieverloo et al 2012). A large variety of invertebrates can proliferate in distribution systems by grazing on biofilms and sediments.…”

“…A large variety of invertebrates can proliferate in distribution systems by grazing on biofilms and sediments. Their abundance and diversity depends on water composition (natural organic matter General introduction (NOM) concentration), pipe materials and retention time van Lieverloo et al 2012;Chapter 9).…”
