Significance of Geologic Features on the Contaminant Migration from Landfill Sites
Contaminants (leachate) migration pathways in various media at hazardous waste and landfill sites are primarily defined by the local geologic features at such sites, namely:stratigraphy,...

Analysis of Exceptional Meteorological Conditions on July and August in Conakry
Conakry is a zone that receives more precipitation than other countries in West Africa. Sometimes the quantity is more than 4,000 mm per year. Strong rainfalls are observed between July...

Hazardous Soil Remediation: A Cooperative Effort between Industry and Government
E. I. du Pont de Nemours and Company's Antioch Works (Dupont) is on the San Joaquin River 30 miles east of San Francisco, California. For about 25 years, ending in 1981, Dupont...

Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...

Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...

Regional Groundwater Management with Health Risk Assessment
A regional groundwater system may have several areas which are contaminated with organic chemicals. In general, the objective of groundwater management is to supply the demand for water...

System of River Floods Warning in Ukraine
The diversity of climatic, geomorphologic, and soil conditions causes significant space differences in the conditions of river flood formation in Ukraine. The Carpathians region is the...

The Use of Monitoring of Russian Water Objects for the Decrease of Disaster Consequences
The project of the United States Monitoring System for Water Resources was created. This system united the possibilities of different kinds of existed systems for observation of water...

A Cost-Effective approach to In Situ Remediation of Soil and Groundwater at a Diesel Fuel Spill Site
A bioventing and groundwater treatment system designed to enhance the natural biodegradation of diesel fuel residuals in soil and prevent further groundwater degradation was installed...

Draining Himalayan Glacial Lakes Before They Burst
Glacial lakes are a common feature of the Himalaya in general and the Khumbu Himal region of eastern Nepal in particular. Some of these glacial lakes are naturally unstable because of...

Management of Contaminated Groundwater Using Natural Attenuation
Many state and federal regulations governing remediation of contaminated groundwater give preference to the implementation of remedial alternatives which are capable of providing protection...

The South Bay Ocean Outfall
For more than 60 years, raw sewage has flowed down the hills of Tijuana, Mexico into the Tijuana River, crossing the U.S.-Mexican border. The sewage contaminates the low-lying river valley...

Release Rates of Radionuclides through a Porous Material-Filled Borehole in a Radioactive Waste Repository

Understanding How to Maintain Compliance in the Current Regulatory Climate

Legal Weight Truck Cask Response to Regulatory Format Thermal Events, Part 2: Containment Seal

Solid Waste and Materials Systems Alternatives Study Summary

Probabilistic Approach for Cancer Risk Assessment
Carcinogenic chemicals have entered ground water systems from surface spills and leaching from subsurface disposal sites. Of particular interest in this study was the contaminant tetrachioroethylene...

A Framework for Sanitation and Health Risk Assessment
This paper summarizes some historical, cultural, and operational responses to risk. Zero risk and zero pollution ideas developed as arguably escapist reactions to stresses of economic,...

Glacier-Generated Floods and Debris Flows
Sudden release of glacially impounded water causes catastrophic floods, known as outburst floods, and ocasionally spawn debris flows that pose significant hazards in mountainous areas....

Preparation of Notification Models Using Continuous Modeling Techniques
Public health departments in many states now require that operators of collection systems notify them of discharges from combined sewer systems soon after these events occur. This allows...
