Estimation of Pollution from Highway Runoff?Initial Results
One of the first tasks in the present effort was to assemble a data base of highway runoff characteristics. In the paper that data base is described, the data are summarized, and best...
Global Water Issues
Five critical global water-related issues are discussed. First is the issue of climatic changes and drought. Unfortunately, the opportunities to construct major irrigation projects are...
Housing and Hazardous Waste Contamination
Problems and Remedies
When hazardous waste sites are discovered in close proximity to residential areas, scientists and engineers are often faced with conducting complex studies involving many government agencies...

This book contains the papers presented at the Engineering Foundation Conference, Urban Runoff Quality, held June 22-27, 1986 in Henniker, New Hampshire. Topics covered include data needs...
Cleaning the Nut Island Outfalls
As an early component of a comprehensive program to reduce pollution in Boston Harbor, two 80-year-old cast-iron outfalls, each 60 inches in diameter and a mile long were cleaned in a...
Bicycle Access: New Boost for Transit Performance
Bicycle-transit linkage is a highly cost-effective strategy for boosting suburban transit performance and ridership and appears to offer significant potential for reducing transit access...
CPM Harnesses Mammoth Powerplant Job
One of the largest air quality control retrofit projects in the U. S. is at the Sammis Plant of Ohio Edison Co., along the Ohio River 40 miles west of Pittsburgh. The coal-fired plant's...
Technology and the Infrastructure Problem
Improvements in infrastructure services are modest, zero, or negative depending on the system examined. Using air transportation as an example, lack of improvement is attributed to constraints...
Earth Retention & Noise Absorption Using Evergreen Planted Walls
There is a new concept in wall design used for retaining walls, free standing noise absorbing walls and rock revetments. The Evergreen System is comprised of large prefabricated concrete...
Golden Gate Bridge: Deck Replacement
A major inspection of the Golden Gate Bridge in 1968-69 found the reinforced concrete roadway of the Bridge to have widespread defects and local failures. Further investigations found...
Carrier Selection under the Airline Deregulation Act
The two major segments of the domestic airline system in the United States, the trunklines and the local service airlines, have, over the years, been regulated by the federal government;...
Trouble in Our Own Back Yard
One million tanks will leak toxic and hazardous substances into the U.S. soil within the next four years. Prevention begins with rapid discovery and probability analysis. Various cleanup...
NPDES Permits for Accelerated Oil & Gas Development
Section 402 of the Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to develop National Pollutant Discharge Elimination System (NPDES) permits for waste discharges...
Oilspill Response Technology for the Arctic
Alaska Clean Seas is a spill response organization whose area of interest includes all of the marine environment surrounding Alaska. It provides support to members in contingency planning,...
Arctic Oil Spills in Relationship to Sea Ice Motion
Sea ice on a scale of a few kilometers must be treated as a granular material rather than a continuum. The floes are in nearly constant motion relative to a fixed frame and each other....
Ice Forces on Port Structures Resulting from Moving Ships
Results are described of experiments carried out in Thunder Bay Harbour in March, 1984, to measure ice forces on a port structure. Ice forces were measured by installing five pressure...
Making Treatment Plants Work
For the most part, past design criteria that have been used were based primarily on historical information from plants that worked or general rule of thumb criteria. With the increasing...
An Ecosystem Approach to Watershed Management
An example is drawn from the Little River Research Watersheds near Tifton, Georgia. Riparian hardwood forests (low management) and upland agricultural fields (high management) are the...
A Methodology of Assessing Nonpoint Source Pollution from Agricultural Watersheds
Appraisals of water quality impacts induced by applying watershed management practices are difficult due to many factors. Lack of existing research data base, the diffusive characteristics...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
