Samples of drinking water from different sources in greater Cairo, Egypt, and bottled drinking water were tested for total coliform, fecal coliform, and coliphage populations. Of the 147 samples tested, 4 samples were positive for both total coliforms and coliphage, 65 samples were negative for total coliforms, fecal coliforms, and coliphage, and 78 samples were positive for coliphage and negat...

BACKGROUND Over four million Canadians receive their drinking water from private water supplies, and numerous studies report that these supplies often exceed the minimal acceptable standards for contamination. Canadians in rural areas test their water intermittently, if at all, and treatment of water from private supplies is not common. Understanding the perceptions of drinking water among resi...

Sarin is now a weapon of the terrorist. Its acute effects are primarily due to unrestricted cholinergic activity at both muscarinic and nicotinic receptors. Treatment is based on the use of large doses of atropine and pralidoxime which may lead to practical problems of sufficient drug supplies for the average hospital. Ventilation may be necessary and present problems. Victim decontamination in...

a good account given as to site, plans, area per patient, arrangement of the administrative units, detail of structure as foundations, walls, floors, roofing, stairs, partitions, windows, woodwork, painting, water supplies, heating, lighting, signalling, plumbing and sewerage, ventilation, refrigeration, elevators. Then follows a chapter on the divisions of a general hospital, administrative de...

BACKGROUND In Canada, the legal responsibility for the condition of private water supplies, including private wells and cisterns, rests with their owners. However, there are reports that Canadians test these water supplies intermittently and that treatment of such water is uncommon. An estimated 45% of all waterborne outbreaks in Canada involve non-municipal systems. An understanding of the per...

This is a vast subject and I cannot hope to do more than touch the fringes of it in the short space allotted to me. Clearly, water is the most important and widely used raw material of all. It is vital in every sense of that word. I t is a primary requirement of vegetable life and of animal life (and here I include human life). I need not stress its many domestic uses. Water is essential in pro...

The review of available data on the concentrations of asbestos in U.S. water supplies suggests that the majority of water consumers are not exposed to asbestos concentrations over 1 million fibers/Liter. A few populations, however, may be exposed to concentrations over 1 billion fibers/L. Of the 538 water supplies for which waterborne asbestos data are available, 8% have concentrations of fiber...

Significant advances in water treatment over the last century have resulted in massive improvements in the microbiological safety of public drinking water supplies in the UK and the developed countries. Incidences of illness due to poor treatment or post-treatment contamination are rare, but when they occur tend to attract considerable media attention. A well managed water treatment works and s...

OBJECTIVE To assess the safety and efficacy of a chlorine dioxide water treatment system in controlling Legionella in a hospital water supply. DESIGN For 17 months following installation of the system, we performed regular water cultures throughout the building, assessed chlorine dioxide and chlorite levels, and monitored metal corrosion. RESULTS Sites that grew Legionella species decreased...
