The paper presents commonly used methodology for assessing damage of water supply networks after a seismic event. relies on deriving and applying so-called vulnerability function. An overview the existing functions is given together with parameters, primarily related to soil deformations, which are influencing assessment. Also, critical review possibility their use given. Finally, by using two ...

This section looks back to some ground-breaking contributions to public health, reproducing them in their original form and adding a commentary on their significance from a modern-day perspective. In this issue, Michael A Lennon reviews the first trial of a fluoridated public water supply. Extracts of the report of the trial by Francis A Arnold et al. in 1956 are reproduced below by permission ...

Previous to 9-11, it was assumed that a combination of small-scale bench testing plus dimensional analysis would be sufficient to model fate and transport of chemical and biological (CB) contaminants in water systems. Water security is a life safety issue. Water supply systems on military installations and forward facilities are vulnerable to both conventional, industrial and military CB agent ...
