An Evaluation of Hazardous Waste Land Treatment Closure Options
The purpose of this research was to evaluate changes in the persistence and mobility of the residues remaining when hazardous waste land treatment (HWLT) sites are closed. This evaluation...
Design and Implementation of a Risk-Based Remedial Action Program for Underground Tank Removal at a Dioxin-Contaminated Site
The unknown or uncertain conditions often inherent in hazardous waste site remediation projects complicate the job of the responsible professional to adequately assess and manage associated...
Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Groundwater Monitoring Network Design Using Coupled Monte Carlo Simulation and Optimization
This paper presents a method for the design, under uncertainty, of a groundwater well network for compliance monitoring at a waste disposal site. A numerical model of contaminant transport...
Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...
Geostatistical Global Estimates and Sampling Design
In the environmental assessment of a contaminated site, several different evaluation criteria could be considered such as: estimation of the overall average contaminant concentration in...
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...
Project Evaluation?Don't Miss the Boat
The hydroelectric developer is faced with many decisions during the evaluation stage. These include determining the size of the project, financial analysis to be used, type and number...
An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...
Licensing the Moose River Hydroelectric Project
This paper describes environmental considerations in the licensing and permitting of the Moose River Hydroelectric Project, a 12.2 MW development in Central New York State. It illustrates...
EPRI's Hydro Relicensing Strategy
The most successful relicensing program is anticipated to involve an aggressive, proactive strategy as follows: select a small, responsive management team to make the decisions concerning...
Evaluation of Hydro Facilities for Sale to Another Utility
STS Hydropower had been contacted by a major industrial client near one of the STS regional offices for the purpose of evaluating both the technical and financial status of several operating...
New Martinsville Hydroelectric Project
The New Martinsville Hydroelectric Project consists of a dual bulb unit, 34 MW powerhouse constructed at an existing lock and dam navigation facility. The project was completed on budget...
Devil Canyon Powerplant Enlargement
This paper presents the design and construction aspects of the enlargement of the existing Devil Canyon Powerplant from 120 MW to 280 MW. Subjects covered include site geology, powerhouse...
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...
Safer Dams
During the last 11 years, thousands earth dams have been inspected. Here are four that were rehabilitated. Army Corps inspections are phase I of the program, and have been completed. The...
Guidelines for Failure Investigation
The
Assessing Site Assessments
Laier and Sibley contend that the growth in environmental site assessments, fast becoming routine in many types of real estate transactions, could create a windfall market for engineering...
