Security Issues in Drinking Water Distribution Networks

This paper formulates the security problem of sensor placement in water distribution networks for contaminant detection. An initial attempt to develop a problem formulation is presented, suitable for mathematical analysis and design. Multiple risk-related objectives are minimized in order to compute the Pareto front of a set of possible solutions; the considered objectives are the contamination...

Measurement of Fluoride Concentration in Semnan Drinking Water Distribution

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...

Water quality modeling in the dead end sections of drinking water distribution networks.

Dead-end sections of drinking water distribution networks are known to be problematic zones in terms of water quality degradation. Extended residence time due to water stagnation leads to rapid reduction of disinfectant residuals allowing the regrowth of microbial pathogens. Water quality models developed so far apply spatial aggregation and temporal averaging techniques for hydraulic parameter...
