Can California Cope With Its Mounting Sludge Volume�

Abstract:

In California, prohibition of ocean disposal of sludge, stringent air quality standards, high energy cost, and scarcity of suitable sanitary landfills make the sludge management problem difficult to solve. Major regional facilities planning studies to find long-term solutions to the sludge problem are being conducted in the Los Angeles�Orange County metropolitan area and in the San Francisco Bay area. Alternatives studied include liquid sludge transport to sites outside the urban area for agricultural use or disposal, composting and marketing, and thermal processing. Lack of reasonable regulations controlling the beneficial use of sludge, and existing policies and regulations with single purpose objectives make sludge management, a multi-media problem, a difficult task.
