Journal ArticleDOI
Microbiology, chemistry and biofilm development in a pilot drinking water distribution system with copper and plastic pipes
Markku J. Lehtola,Ilkka T. Miettinen,Minna M. Keinänen,Tomi K. Kekki,Olli Laine,Arja Hirvonen,Terttu Vartiainen,Pertti J. Martikainen +7 more
TL;DR: The formation of biofilm was slower in copper pipes than in the PE pipes, but after 200 days there was no difference in microbial numbers between the pipe materials, and thereafter there were no differences between the two pipe materials.
Journal ArticleDOI
The effects of changing water flow velocity on the formation of biofilms and water quality in pilot distribution system consisting of copper or polyethylene pipes.
Markku J. Lehtola,Michaela Laxander,Ilkka T. Miettinen,Arja Hirvonen,Terttu Vartiainen,Pertti J. Martikainen +5 more
TL;DR: The formation of biofilms increased with the flow velocity of water and the increase in microbial numbers and contents of ATP was clearer in the PE pipes than in the copper pipes, indicating that the mass transfer of nutrients is in major role in the growth of bioFilms.
Journal ArticleDOI
Norovirus Outbreaks from Drinking Water
TL;DR: Norovirus contamination calls for viral monitoring of drinking water in Thailand for the first time.
Journal ArticleDOI
Mycobacteria in Water and Loose Deposits of Drinking Water Distribution Systems in Finland
Eila Torvinen,Sini Suomalainen,Markku J. Lehtola,Ilkka T. Miettinen,Outi Zacheus,Lars Paulin,Marja-Leena Katila,Pertti J. Martikainen +7 more
TL;DR: The results indicate that drinking water systems may be a source for recently discovered new mycobacterial species and correlation with the concentration of assimilable organic carbon in the water leaving the waterworks.
Journal ArticleDOI
Survival of Mycobacterium avium, Legionella pneumophila, Escherichia coli, and caliciviruses in drinking water-associated biofilms grown under high-shear turbulent flow.
Markku J. Lehtola,Eila Torvinen,Jaana Kusnetsov,Tarja Pitkänen,Leena Maunula,Carl-Henrik von Bonsdorff,Pertti J. Martikainen,Sandra A. Wilks,C. William Keevil,Ilkka T. Miettinen +9 more
TL;DR: It is proved that pathogenic bacteria entering water distribution systems can survive in biofilms for at least several weeks, even under conditions of high-shear turbulent flow, and may be a risk to water consumers.
