Using Geophysics to Assess Geohazards Before Construction: Increase Your Odds for Success!
Understanding subsurface conditions is the key to any successful construction project, including new construction, excavation, and drilling. The consideration and understanding of the subsurface geology...

Optimization of Well Placement in Groundwater Long Term Monitoring Networks
Long Term Monitoring (LTM) networks play critical roles in tracking the migration of contaminants in groundwater, evaluating the efficiency of the existing remediation techniques, and...

Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....

The Cyanic Threat
In the past terrorists have attempted to contaminate drinking water supplies in the United States with cyanide - one of the most lethal poisons known to man. So far they have been unsuccessful....

Rapid Delivery
Facing nearly dry wells and a moratorium on development that was about to expire, a small town in the pacific Northwest, using the design/build delivery method, was able to quickly design...

Use of Piles and Deep Well Pumping in Slide Stabilization

A Risk-Based Approach to Subsurface NORM Disposal
(No paper) Naturally occurring radioactive materials (NORM) has become an environmental concern for the petroleum industry. NORM scales results when naturally occurring radium co-precipitates...

Rising Water and Nitrate Levels within an Alluvial Aquifer near Phoenix, Arizona
(No paper) An analysis of water level data from more than a hundred water supply wells show that water levels have been rising at a considerable rate since 1980 in some portions of the...

Oil in the Soil
An oil well blowout in northern Italy contaminated about 1,500 ha of agricultural land primarily used to cultivate rice. The cleanup team decided to use bioremediation techniques because...

Pump-and-Treat Rescue
The pump-and-treat method of remediation has been regarded for years as unsuccessful and untrustworthy. But a recent project in Chicago showed that in conjunction with horizontal wells...

The WELLSIM Model for Analyzing Well Hydrodynamics

A Risk/Cost Analysis of a Hazardous Waste Site

Preparing for Pier A
Earthquakes, oil wells, contamination and unstable soil were among the challenges engineers faced as they prepared a site at California's port of Long Beach for the Pier A...

Contaminant Mean Arrival Times at Pumping Wells in Heterogeneous Formations

Detailed 3-D Field Experiments with a Groundwater Circulation Well for Aquifer Remediation

Analysing the Impact of Well Hydraulic Properties on Well Inflows in Fissured Porous Aquifers

Newport News: Brackish Water Gets Fresh
Rapid growth was straining freshwater supplies in Newport News, Virginia. Studies showed Newport News Waterworks that they could be facing a 30 mgd deficit by 2040 and ran a 50% chance...

Remediation of a Contaminated Thin Aquifer by Horizontal Wells

Making a Map of Public Health Hazards
Accurately deducing the long-term exposure of community members to health hazards has always been a challenge for engineers. In 1993, the town of Somers, Conn., discovered a residential...

A New Direction in Remediation
Engineers have always had to rely on wells for onsite soil and ground water remediation systems. During the past several years, horizontal drilling technology, adapted from oil recovery...
