Safe Piped Water: Managing Microbial Water Quality in Piped Distribution Systems
TLDR
The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this paper, as well as the practices of water supply organizations that can directly or indirectly influence their presence.Abstract:
The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this book, as are the practices of water supply organisations that can directly or indirectly influence their presence and growth. The information and conclusions are intended for policy makers and those responsible for formulating "Water Safety Plans" for the supply of drinking-water. It is also relevant to engineers and scientists who are responsible for water supply planning, operations and monitoring.
The review shows that there are often public health reasons for adopting a more proactive approach to many of the traditional practices used in designing, operating and maintaining distribution networks, and to modifying the composition of the water that is fed into the network.

Mycobacteria in drinking water distribution systems: ecology and significance for human health.
TL;DR: Although the presence of EM in tap water has been linked to nosocomial infections and pseudo-infections, it remains unclear if these EM provide a health risk for immunocompromised people, in particular AIDS patients.
Water safety plan manual: Step-by-step risk management for drinking-water suppliers.

TL;DR: Water safety plans (WSPs) as discussed by the authors are the most effective means of consistently ensuring the safety of a drinking-water supply is through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer.

Potential impacts of changing supply-water quality on drinking water distribution: A review
Gang Liu,Ya Zhang,Willem Jan Knibbe,Cuijie Feng,Wen Tso Liu,Gertjan Medema,Walter van der Meer +6 more
TL;DR: The contaminants that develop in the water distribution system and their characteristics are reviewed, as well as the possible transition effects during the switching of treated water quality by destabilization and the release of pipe material and contaminants into the water and the subsequent risks are reviewed.

TL;DR: In soil, fertilizers containing inorganic nitrogen and wastes containing organic nitrogen are first decomposed to give ammonia, which is then oxidized to nitrite and nitrate, which are taken up by plants and used in the synthesis of organic nitrogenous compounds.

TL;DR: Both bloody and nonbloody diarrhea may be common manifestations of this infection, which is probably underdiagnosed because of the failure of routine stool cultures to identify the organism.

TL;DR: In water microcosm experiments, Campylobacter isolates differed by up to twofold, as determined by culturing; this difference increased to fourfold when particular combinations of temperature and oxygenation were used.
