Deck Park Covers Phoenix Freeway
The last link in interstate I-10, the coast to coast highway from Florida to California, will be completed in Phoenix, Arizona in 1989. The last eleven-mile section through Phoenix has...

The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...

State-of-the-Practice Mitigation Measures for Collapsible Soil Sites
Mitigative alternatives for collapsible soil sites are reviewed considering shallow, as well as deep, collapsible soil deposits. In the case of deep soil deposits the overburden pressures...

Occupational and Environmental Exposures to Radon: A Perspective for Mitigators
Occupational exposures to radon and radon decay products and the associated high incidence of radiation induced lung cancer form the basis for our present-day concern for limiting exposures...

Technical Issues Related to Emission Releases from Subslab Radon Mitigation Systems
Surveys of government and private sector radon mitigation activities indicate that subslab radon mitigation systems account for more than 50 percent of all installed systems. Such systems...

A Real-time Approach to Groundwater Monitoring, Prediction, and Remediation
This paper outlines a integrated approach to the problem of predicting and controlling groundwater contamination. The key to this approach is to derive contaminant predictions by combining...

Mitigation of Ice Effects at Hydroelectric Intake Structures
The design and operation of hydroelectric facilities throughout the northeast United States and Canada must contend with winter conditions for a large part of their yearly operation. During...

Radio Telemetry as a Tool for Fisheries Mitigation
Monitoring discrete fixed locations requires automated receivers and data loggers while manned, mobile receivers are more suited to general movement or habitat studies. Of the three tagging...

Augering Answers
Leaking storage tanks, a long time environmental problem, are now being addressed nationally with cleanup regulations. Clearly, inexpensive and quick remediations are needed. This article...
