For Whom the Bugs Toil
Bioventing is soil ventilation intended to enhance the biodegradation of petroleum hydrocarbon contaminants in soils by providing a supply of oxygen. Soil microbes are capable of consuming...

Nature's Payback (Available in Geoenvironmental Engineering Special Issue)
Environmental compensation is now a major concern for utilities and other developers who must compensate for impacting wetlands, streams and other environmentally-sensitive areas. To meet...

Manufactured Gas Plants: Yesterday's Pride, Today's Liability
Manufactured gas plants were the pride of the industrialized world until cleaner, natural gas pipelines were built beginning in the 1930s. Most gas plants had closed by the 1960s, leaving...

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...

Natural Gas Systems
This section provides an overview of natural gas systems, including their major components and subsystems. Also present is a guide for a post-earthquake investigation of gas systems....

Pipeline Needs, Technology Opportunities for Natural Gas Transmission Systems

Pipeline Research Needs

Pipeline Safety and Protection

Ground-Water Treatments Gain Ground
Ground water is the main source of the nation's public water supplies and is also used extensively for agricultural and industrial purposes. Yet our reserves are constantly...

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...

Biological Clogging and Rehabilitation of Drains and Well Systems and the Implications on Groundwater Quality

A Multiperiod Approach for the Solution of Groundwater Management Problems using the Outer Approximation Method
In a previous work the Outer Approximation method was presented (Karatzas and Pinder, 1993 and 1996) for the solution of groundwater management problems where the selected pumping rates...

Comparison of Stochastic Programming and Robust Optimization Models for Groundwater Plume Containment
Stochastic optimization models for containing a groundwater contaminant plume through the installation and operation of pumping wells are developed. Two related formulations are presented—stochastic...

Flexible Water Deliveries: One District's Experience
The Merced Irrigation District (MID) has implemented two significant incentive programs in 1995 to provide surface irrigation water to farmers who have shifted to private wells for irrigation....

Artificial Recharge of a Buried Glacial Aquifer in South Dakota
The Huron Project of the High Plains States Groundwater Demonstration Program was designed to artificially recharge a buried glacial aquifer in eastern South Dakota High flows from the...

Production of Nitrous Oxide Gas under Sequencing Batch Reactor System
N2O, like CO2, H2O, and CH6,...

Optimal Well Locations for Groundwater Mound Control

Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...

Wellhead Protection Area Predictions and Implications for the Biscayne Aquifer in Miami, Florida
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....

Wellhead Protection: Local and Community Efforts
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....
