Closure of Hazardous Surface Impoundments and Creation of an On-site Permanent Disposal Facility?A Case History
Remington Arms Co. is currently undertaking a RCRA closure program for nine surface impoundments in Lonoke, Arkansas. The impoundments contain a variety of listed hazardous wastes from...
Hazardous Waste Impacts on the Highway Planning and Property Acquisition Process
Since the advent of increased public awareness concerning hazardous waste and the enactment of statutes governing these wastes, hazardous waste has become an important component impacting...
Computerized Data Processing, Displays and Groundwater Flow Analyses of the Stringfellow Hazardous Waste Site
Several types of data, maps, and figures were obtained from various sources involved in the investigations and monitoring at the site. This information was discretized, and a computerized...
Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...
An Expert System for Groundwater Management with Applications to Collier County, FL

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...
The Utilization of a Deflocculant to Decrease the Permeability of a Clay Liner
A hazardous waste landfill was completed in Oklahoma during 1988. The clay liner was constructed to fulfill the RCRA requirements for permeability of equal to or less than 1E-07 centimeters...
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...
The Water Erosion Prediction Project: Model Overview
A new generation of water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The WEPP models are a new erosion prediction technology...
Attitudes and Health Effects of Water Reuse
This paper is concerned with public attitudes toward water reuse for irrigation and with the consequences of human contact with reclaimed wastewater. Initially, attitudes are considered...
Parameter Identifiability in Conceptual Rainfall?Runoff Models
Computers have played a major role in the evolution of hydrologic rainfall-runoff models. Besides providing the computational power required for the simulation of the complex interacting...
TVA Weekly Scheduling Model Application Experience
Development of TVA's Weekly Scheduling Model was completed in 1980. Eight years of experience covering a wide variety of applications has now been accumulated. Since the basic...
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
