Hygienic Analysis of some of the Potable Waters of Brookings
<p>Introduction: While it is universally recognized that there is a difference between good and bad drinking water, few realize how important a part water plays in producing or destroying health. Comparatively recent investigation has shown that water forms the most active agent in the production …

Solar-driven humidification dehumidification desalination for potable use in Haiti
Worldwide water scarcity, especially in the developing world, provides the impetus for utilizing inexpensive desalination technologies on a wider scale to contribute to freshwater supply. Small-scale desalination technologies, such as solar-driven humidification dehumidification (HDH), are needed …

Non-Uniform Copper Corrosion in Potable Water: Theory and Practice
While it has long been known that water flow can influence non-uniform corrosion of copper pipe (Rushing 2002, Marshall 2004), it has never previously been considered a primary contributor to the problem. This work is the first to describe a fundamentally important phenomenon in aqueous non-uniform …

Determination of the Influence of Polyurethane Lining on Potable Water Quality
… about the effects of polyurethane to reline potable pipes. Polyurethane has only recently begun to be approved by the U.S. Environmental Protection Agency for use in drinking water piping, although it has been used in the United Kingdom since 1999. The American National Standards …

An Evaluation and Pressure-Driven Design of Potable Water Plumbing Systems
Potable water distribution systems are broken into major and minor distribution networks. Major water distribution networks refer to large-scale municipal pipe systems extending from the treatment plant to the upstream node of the water service line for buildings. Minor water distribution systems, …

MEASURING AND MODELING POTABLE WATER DEMAND IN THE UNITED STATES VIRGIN ISLANDS
… and model-based approach to measure and estimate potable water flows in the United States Virgin Islands (USVI). The USVI potable water system is considerably more complicated than typical systems in the mainland United States. For this reason, we conduct a first-principles analysis on water …

Insights Into Non-Uniform Copper and Brass Corrosion in Potable Water Systems
Non-uniform corrosion of copper and brass in potable water systems poses both economic and environmental problems associated with premature plumbing failures and release of metals. With respect to copper pitting corrosion, it was found that forensic testing (i.e., in pipe-loops) is the only …

Risk-based Renewal Prioritization Models (RPM) for Potable Water Pipeline Infrastructure Systems
Water pipelines are critical infrastructure assets buried across the United States, responsible for delivering safe drinking water at adequate pressures from source to customers. A majority of these pipelines were installed in the mid-twentieth century without adequate financial planning for future …

Development of Soluble Manganese Sorptive Contactors for Enhancing Potable Water Treatment Practices
Without proper removal at a water treatment facility, the soluble manganese (Mn) concentration can reach and exceed the Secondary Maximum Contaminant Level (SMCL) of 0.05 mg/L in the water distribution system. At this level, soluble Mn can be oxidized to solid Mn-oxide particulates, leading to …
