Geostatistics in Estimating Chemical Residuals at a Site
Kriging with generalized covariances is used to evaluate the effectiveness of remediation and cleaning of a contaminated site. The goal is to estimate: a) the amount of total volatile...
Two-Dimensional Inter-Rill Flow Model for the Analysis of Agricultural Runoff
This paper presents a model describing the flow field for the inter-rill component of agricultural runoff. Given rainfall intensity, surface roughness, rill spacing, and longitudinal and...
Environmental Engineering
The 1989 Specialty Conference on Environmental Engineering was held in Austin, Texas on July 10-12, 1989 with cooperation from the University of Texas at Austin Civil Engineering Department...
Putting Waste to Use
Although it's only been nine years since Superfund was passed, a traditional hazardous waste disposal process has nontheless been established. That is, wastes are taken to...
Training the Waste Watchers
Whether an engineer is going to work at a Superfund site himself, or if his firm will be doing cleanup work at the site, that engineer will want to take the 40 hour training course as...
A Hazardous Data Explosion
During the 1980s, public concern and government regulations have spawned the huge hazardous waste management industry. But the industry has opened a Pandora's box for site engineers, most...
A Case Study of Hydropower Operation Based on Runoff Forecast
The intent of this paper is to outline a forecast approach developed to enable the operation of power storage projects, and to illustrate from employing the approach that overall system...
Geotechnical Exploration and Site Preparation Techniques for Large Mall in Karst Terrain
A large commercial mall and secondary developments were planned for construction in a karst area near Clarksville, Tennessee. A geotechnical exploration was conducted to evaluate the occurence...
Recent Progress in Coal Ash Utilization and the Effect of Environmental Issues and Regulations
This paper summarizes for civil engineers several publications that help to specify and use coal combustion by-products in construction and other applications in a technically sound, commercially...
Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...
Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...
Trends and Emerging Issues: A Longitudinal Study of Government Agencies' Perceptions of Great Lakes Water Resources and Related Issues
The perceptions of government agencies with jurisdiction over Great Lakes' shoreline has changed over time with respect to important issues related to water quality and a...
Leachate Flow Through Landfills
The problem of estimating the amount of leachate generated in a landfill site is of significance in the assessment of potential environmental impacts. Although there are a variety of regulations...
Resolution of Conflicts in Superfund Site Cleanups
In this paper, we present the typical sequence of tasks involved in the cleanup of a Superfund site under current regulations and guidance. We then pinpoint the areas where conflicts arise...
Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...
Lessons to be Learned from Lafayette Tennessee's Small Diameter Sewer System
Lafayette, Tennessee's septic tank effluent, small diameter gravity sewer (SDGS) system is believed to have been the first such project to be funded by the United States Environmental...
Foam Over Troubled Toxics
Foams are now being used to control noxious vapor emissions from hazardous waste landfills. Another use of foams is in control of vapors emitted by chemical spills and fires. This article...
Take Back the Land
Municipal sludge applied to land devastated by strip mining has brought thousands of acres of Ohio, Illinois and Pennsylvania land back to life. After two years of testing at a Palmerton,...
EPA: Siting Permanent Solutions
EPA's SITE (Superfund Innovative Technology Evaluation) program is entering its third year. It is designed to speed up hazardous waste treatment technology. The program helps...
Speaking of RISK
With sensitivity, common sense and preparation, an engineer can explain risk effectively and fairly without alienating the public. Risk communicators should use a standard set of terms...
