BACKGROUND Access to adequate quantities of water has a protective effect on human health and well-being. Despite this, public health research and interventions are frequently focused solely on water quality, and international standards for domestic water supply minimums are often overlooked or unspecified. This trend is evident in Inuit and other Arctic communities even though numerous transmi...

BACKGROUND As the population and demand for safe drinking water from domestic wells increase, it is important to examine water quality and contaminant occurrence. A national assessment in 2006 by the U.S. Geological Survey reported findings for 55 volatile organic compounds (VOCs) based on 2,401 domestic wells sampled during 1985-2002. OBJECTIVES We examined the occurrence of individual and m...

The regional water allocation planning is one of those complex decision problems where holistic approach to water supply management considering different criteria would be valuable. However, multi-criteria decision making with diverse indicators measured on different scales and uncertainty levels is difficult to solve. Objective of this paper is to develop scenarios for the future imbalances in...

Fecal-oral pathogens are transmitted through complex, environmentally mediated pathways. Sanitation interventions that isolate human feces from the environment may reduce transmission but have shown limited impact on environmental contamination. We conducted a study in rural Bangladesh to (1) quantify domestic fecal contamination in settings with high on-site sanitation coverage; (2) determine ...

Naturally occurring arsenic contamination is common in ground water in the upper Midwest. Arsenic is most likely to be present in glacial drift and shallow bedrock wells that lie within the footprint of northwest provenance Late Wisconsinan glacial drift. Elevated arsenic is more common in domestic wells and in monitoring wells than it is in public water system wells. Arsenic contamination is a...

Sydney’s water supply is under great pressure as the demand continues to rise. Demand mitigation strategies have had some success, but domestic consumption remains high. This paper discusses the attitudes of households to their water consumption in a search for ways in which domestic demand for water may be reduced. Evidence on attitudes of households in different kinds of housing was obtained ...

Abstract As the world increasingly faces water shortages, it is critical to develop realistic estimates of consumption based on water-use activities rather than top-down imposed limits. This study quantifies absolute basic (ABC) an individual, irrespective location or source, with a focus personal measured household consumption. A theoretical model stochastically describe 21 was developed, corr...

The international maritime disputes in the South China Sea have now escalated following China’s construction of man-made islands and a new United States Naval presence that includes a guided missile destroyer. However, territorial claims between the nations surrounding these waters are not new. As both a major global shipping lane (it is considered one of the most trafficked sea lanes in the wo...

Male-specific bacteriophage (MSB) densities were determined in animal and human fecal wastes to assess their potential impact on aquatic environments. Fecal samples (1,031) from cattle, chickens, dairy cows, dogs, ducks, geese, goats, hogs, horses, seagulls, sheep, and humans as well as 64 sewerage samples were examined for MSB. All animal species were found to harbor MSB, although the great ma...

In China, domestic ducks and wild birds often share the same water, in which influenza viruses replicate preferentially. Isolation of 2 novel reassortant highly pathogenic avian influenza (H5N5) viruses from apparently healthy domestic ducks highlights the role of these ducks as reassortment vessels. Such new subtypes of influenza viruses may pose a pandemic threat.
