Evaluation of Iron Corrosion Release Models for Water Distribution Systems
Customer complaints of red water problems remain to be a frequent occurrence for water utilities. While material sources may vary, it is generally accepted that iron rust resulting from corrosion of iron based pipes is the predominant cause of red water issues. Recent efforts have lead to the …

Conditioned taste and visual aversions in chicks: effects of social transmission of acquired behavior
… Following aversion conditioning to a visual (red water) or taste (3% vinegar) CS, 80 chicks individually observed an audience of two conspecifics ingest the aversive CS or observed a nondrinking audience in the presence of the CS. Observation of a drinking audience reduced the magnitude of the …

Relative Effects of Water Chemistry on Aspects of Iron Corrosion
… of all publicly and privately owned potable water pipes in the U.S. is on the order of $2.4 trillion dollars, and costs associated with deteriorating iron pipes is billions of dollars per year. Problems arising from iron corrosion include reduced lifetime of the material, scale buildup and …

A questionnaire and a concentrator sampling technique used to evaluate water quality degradation in water distribution systems
… examination of microbially-caused degradation of water quality within water distribution systems were considered: the results of a questionnaire were analyzed and a sampling technique utilizing a concentrator was evaluated. A questionnaire, completed by water treatment plant operators in Virginia, …

The Effect of Water Chemistry on the Properties of Iron Particles and Aqueous Iron Suspensions Derived From the Oxidation of iron(II)
… the stability and mobility of iron particles in water, and the color and turbidity of aqueous iron suspensions. Their properties are also important in source water iron removal effectiveness, particle deposition rates, and the transport of adsorbed contaminants such as organic matter, e.g., …

Exploration of the spatial epidemiology of tick borne pathogens of livestock in Southern Cumbria
… evidence, Babesia divergens (the agent of red water fever in cattle) was notfound at any of the sites. However, the discovery of B. venatorum in a new area of the UK is ofpotential medical importance. In addition to the confirmation of B. OO-2012, and a B. odocoilei- likespecies; this, to …

The Influence of Water Chemistry on H2 Production and Uptake during Anaerobic Iron Corrosion
… and aesthetic problem facing utilities. In the water distribution system, problems caused by iron corrosion include "red water", scale buildup, and pipe failures. It is necessary to improve our mechanistic understanding of anaerobic iron corrosion in order to better address these concerns. …

Role of Chloride in Galvanized Iron Plumbing Corrosion and the Use of Fingerprinting Methods to Identify Water Lead Sources
In many source waters across the United States (US), chloride levels are increasing and this change could be problematic for galvanized iron pipe (GIP) installed in consumers' homes and buildings. The higher levels of chloride might increase the rate of galvanic corrosion between the sacrificial …

Lead and Copper Contamination in Potable Water: Impacts of Redox Gradients, Water Age, Water Main Pipe Materials and Temperature
Potable water can become contaminated with lead and copper due to the corrosion of pipes, faucets, and fixtures. The US Environmental Protection Agency Lead and Copper Rule (LCR) is intended to target sampling at high-risk sites to help protect public health by minimizing lead and copper levels in …
