Corps Developing Wildlife Habitat to Solve Disposal Problems
The large volume of sediments dredged each year by the Corps of Engineers from navigable waterways can be considered a resource instead of a waste product, and used as a substrate for...
EPA Launches Program to Control Hazardous Wastes
In January 1979, the federal Environmental Protection Agency will issue its long awaited guidelines on the control of hazardous wastes. These guidelines will propose a so-called manifest...
Geotechnical Practice for Disposal of Solid Waste Materials
The papers for this conference are grouped under the themes of four of the general sessions: 1) Geotechnical properties affecting disposal and utilization; 2) utilization in dams, embankments,...
Alternatives to End-of-Pipe Treatment
End-of-pipe treatment must be replaced by innovative, in-process changes if industrial plants are to creatively meet the upcoming 1983 EPA pollution control requirements. By-product recovery,...
Waste Clearinghouse Promotes Recycling Efforts
Industrial waste management has emerged as a major problem for all industrial nations. The EPA recently estimated that approximately 260,000,000 dry tons of waste materials are generated...
ASCE Sharpens Committee Management
With some 500 committees and $500,000 a year spent on committee travel, ASCE has a management challenge. To avoid waste and boost performance of committees, recently the Society asked...
California's Food Industry: Wastewater Management Challenge
The demand for food products throughout the United States and the world has been partially responsible for the continuous growth of agriculture and food processing in California. This...
Energy Utilization and Conservation in Wastewater Treatment
Rising costs of energy, and its limited supply in the United States, is requiring engineers to investigate the application of energy efficient processes for wastewater treatment. Energy...
Reviving the Septic Tank
Although collection and secondary treatment systems serve most U.S. Metropolitan areas, approximately 25% of the population still depends on individual sewage waste disposal systems. Estimates...
Cost-Effectiveness of On-Site and Community Sewerage Alternatives
Some research and development work has taken place, over many years, on individual on-site treatment and disposal systems as well as non-conventional systems. Most recent work, however,...
New Gravity/Pressure Unit Cuts Sludge Dewatering Costs
A new device for dewatering sludges from either industrial or municipal waste treatment plants promises to cut both initial capital and operating costs over more traditional methods such...
Wastewater Ozonation: A Process Whose Time Has Come
For many years, ozonation has been a technically viable solution to difficult waste treatment problems. Not until recently, though, has ozonation found growing acceptance as a cost-effective...
PL 92-500 to Cost Metal Finishing Industry $45 Billion
The 1972 amendments to the Water Pollution Control Act will have far their greatest impact on the metal finishing industry. To meet the 1983 requirement of best available technology is...
County Treats Shredfill Leachate
The project in Cowlitz County, Washington, is the first sanitary shredfill (landfill) to have full environmental control. Shredding refuse has long been deemed superior to ordinary landfilling...
Industrial, Municipal Wastes Combined
The design of the facility in South Paris, Maine, is based on a modified secondary activated sludge treatment process. Because of the quality of the specific industrial wastes being treated,...
Land Application of Residual Materials
Proceedings of the Engineering Foundation Conference held in Easton, Maryland, September 26-October 1, 1976. Sponsored by the American Society of Civil Engineers.
Designing More Reliable Waste Treatment Plants
In the past, many municipal waste treatment plants have not operated reliably. A 1969 Federal Water Pollution Control Administration Study, for instance, showed that 25% of 1500 plants...
Corps Guidelines for Dam Safety Inspection Need Revamping
A protest (1) that Proposed Guidelines for Safety Inspection of Dams, Federal Register, August 1974, pp. 31334-31346, ignores well-publicized conclusions of a preexisting ASCE task committee...
New Method Dewaters Dredged Material, Cuts Lagooning Space
Disposal of the millions of cubic yards of dredged material produced each year in the maintenance of the nation's waterways is becoming a serious problem. Traditional methods...
Tough Pollution Laws Spur Use of Impermeable Liners
Consultants have increasingly been using flexible, synthetic linings for a variety of civil engineering applications. The U.S. Dept. of Agriculture has been using membranes to line irrigation...
