This research addresses water quality issues in water distribution systems in general, and more specifically, pipe corrosion which can entail many adverse effects including reduction of hydraulic capacity, compromised structural integrity of conduits and water quality deterioration. Yet, for all its familiarity, corrosion is a complex phenomenon due to the inter-dependent set of reactions that can take place at the pipe wall with chemicals in the bulk water. The principle objective of this study is to extend the existing, but basic, 1-D corrosion-water quality model and to explore the impact of various chemical species on the formation of ferrous and ferric ions during transient conditions. In addition, the associated formation of various iron precipitates is numerically explored. Each chemical species is tracked using the ADRE which is coupled with a hydraulic model. The numerical outcome of the model is compared with the results of the existing model, with both exhibiting good agreement.

This research studied the use of multi-element sensors based on electrochemical techniques for optimizing information related to corrosion control in water distribution systems. Such on-line sensor methods could provide an affordable and reliable tool for daily monitoring and mitigate some of the costs associated with following the mandates of the EPA's corrosion control for potable water.

Low or negative pressure transients (also called surge or water hammer) create temporary opportunities for external chemical and microbial contaminants at higher pressure to enter the water distribution system, creating potential health hazard and potential weakening of distribution pipes, leading to failure. This study investigates how such events as power outages, pump shutdowns, valve operations, main flushing, firefighting, and main breaks can create significant rapid, temporary drops in system pressure. The report offers useful recommendations for using surge models to optimally locate pressure monitors and to minimize the occurrence and impact from low- and negative-pressure transients.

Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

ABSTRACT Cont.'d : Molecular weight (MW) distributions of DBPs precursor (DOM) revealed that the higher molecular weight fractions adsorbed preferentially onto goethite followed by magnetite surface. The change of MW distribution of DOM was found to be in reasonable agreement with the change of DBPs formation in iron-water systems.
