TLDR
The drinking water distribution system of the city of Metz in France was sampled intensively during six, monthly surveys which were designed to determine the spatial and temporal distribution of total heterotrophic bacteria in the network.About:

Journal ArticleDOI
Biological Stability of Drinking Water: Controlling Factors, Methods, and Challenges
E.I. Prest,Frederik Hammes,Mark C.M. van Loosdrecht,Johannes S. Vrouwenvelder,Johannes S. Vrouwenvelder +4 more
TL;DR: How knowledge gained from novel techniques will improve design and monitoring of water treatment and distribution systems in order to maintain good drinking water microbial quality up to consumer’s tap is discussed.
Journal ArticleDOI
Biofilms and bacterial drinking water quality
TL;DR: The results indicate that biofilm growth and detachment accounted for most, if not all, the planktonic cells present in the bulk water of a chlorine free system.
Journal ArticleDOI
Chlorine decay in drinking-water transmission and distribution systems: pipe service age effect.
TL;DR: The results showed that pipe service age was an important factor that must not be ignored in some pipes such as cast iron, steel, cement-line ductile iron (CLDI), and cement-lined cast iron ( CLCI) pipes especially when the bulk decay is not significant relative to the wall decay.
Heterotrophic Plate Counts and drinking water quality
TL;DR: Heterotrophic Plate Counts and drinking water quality as discussed by the authors, which is a method for counting the number of plate points in a plate set, has been shown to improve water quality.

Effect of Disinfectant, Water Age, and Pipe Material on Occurrence and Persistence of Legionella, mycobacteria, Pseudomonas aeruginosa, and Two Amoebas
Hong Wang,Sheldon Masters,Yanjuan Hong,Jonathan Stallings,Joseph O. Falkinham,Marc Edwards,Amy Pruden +6 more
TL;DR: In this article, the influence of pipe materials, disinfectant type, and water age on occurrence and persistence of three opportunistic pathogens (Legionella pneumophila, mycobacteria, P. aeruginosa, and both amoebas) was examined.

Journal ArticleDOI
A new medium for the enumeration and subculture of bacteria from potable water.
TL;DR: Results from parallel studies with spread, membrane filter, and pour plate procedures showed that R2A medium yielded significantly higher bacterial counts than did plate count agar, and the magnitude of the count was inversely proportional to the incubation temperature.
Journal ArticleDOI
Bacterial density in water determined by poisson or negative binomial distributions.
TL;DR: The question of how to characterize the bacterial density in a body of water when data are available as counts from a number of small-volume samples was examined for cases where either the Poisson or negative binomial probability distributions could be used to describe the bacteriological data.
