Down on the Farm
A `total approach' to sludge handling, from nitrogen management to sub-surface injection lines, helps grow corn in Colorado. Engineers have gone a long way to keep things...
Coal Gas Legacy
The remains of a former coal gasiication plant were uncovered during redevelopment of a site for the new City Hall in Waterloo, Ont. The coal tar waste was a dense, immiscible tarry fluid...
What's Wrong With Superfund
In nine years of the federal government's Superfund program, $4 billion has been spent and only 38 of the 1,175 sites on the national priority list have been cleaned. There...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Fast Tracking Military Waste
The installation restoration program, the military version of Superfund, helped fast track the cleanup contracts for four military hazwaste sites located at Hanscom Air Field, Bedford,...
The Saga of Senate Bill 2067
With the advent of the California Superfund program, liability related to toxic waste cleanup became a critical issue in California. The state had no authority to indemnify consultants...
The Model Cleanup
