Arresting a Toxic Plume
At an abandoned gravel pit in New Hampshire turned into a dump site for hazardous liquid chemical wastes (as well as drummed solid waste), engineers had to race against the clock to stem...
In Third World Villages, a Simple Handpump Saves Lives
Millions die each year and many more suffer in the developing countries from diseases spread by contaminated water. In fact, it is estimated that 80% of all disease in the world is due...
Lining Tunnels: Toughest Concreting Job?
Concrete linings for water supply tunnels must resist sulphate and other chemical attack, not contribute pollutants to the water it is carrying, and not leak for its design life, which...
Frost Inducing Slides on Membrane-Lined Canal Slopes
Freezing beneath a polyvinyl chloride membrane lining caused water in the subgrade soil voids to migrate upward and to form thin ice lenses under the lining. During a spell of warm weather,...
Progress Since 1979 in Sweden
During the past 20 years hard effort has been devoted to the protection of rivers and lakes from pollution. This effort has mainly been focused on the obvious sources of pollution i. e....
