Are constructed wetlands an effective management strategy for restoring and protecting the Everglades from phosphorus over-enrichment caused by agricultural stormwater runoff? The $13.85...
Rehabbing for Remediation
Workers for Moses Lake detected trichloroethylene (TCE) in three of the city's water wells. The concentrations were low, around 5 to 15 parts per billion, just above the maximum...
A Method for Locating Spikes in a Measured Time Series
Raw directional wave sample time series are frequently contaminated with spikes from various sources. The standard procedure in correctly editing these time series includes locating and...
Bio-Remediation of Simulated Fire Training Facility
A leaking aviation fuel underground storage tank system utilized for fire fighting training at the Will Rogers World Airport was removed by Oklahoma City Department of airports personnel....
Airports and Air Quality Issues - the European Perspective
This paper presents a detailed review of air quality studies at European Airports since 1986. It also provides a brief analysis of the air quality section of a recent ACI (Europe) environmental...
Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...
Groundwater Management and Systems Operations Optimization Utilizing Supply, Well Reliability, and Demand Distribution as Decision-Making Criteria
Houston, Texas has a water supply system comprised of both ground and surface water sources serving a population of 2.2 million people through 5,000 miles of water lines and 357,000 water...
Dry Weather Stormwater Management - Yakima, WA
The city of Yakima recently completed a Comprehensive Stromwater Management plan to: 1) assess current and projected local runoff quality and 2) develop strategies to improve receiving...
Wind Lake Improvement Plan Dredging Project Wind Lake, Wisconsin
Dredging has been used historically to improve navigation, however, it usefulness as a water quality improvement tool has not been widely proclaimed. Although costly to undertake, dredging...
Optimal Groundwater Reclamation with Captial Costs
A dynamic optimal control model for groundwater remediation was extended to incorporate treatment facility capital costs. Incorporation of the capital costs had the greatest impact on...
Optimization of the Design and Operation of Soil Vapor Extraction Systems
Volatile organic compounds (VOC's) immobilized within the soil unsaturated zone constitute a significant source of groundwater contamination. Soil vapor extraction systems (SVES's), which...
Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
Fort Bend County Surface Water Supply Study
Fort Bend County encompasses approximately 876 square miles in southeast Texas near the Gulf of Mexico. The County's sole source of potable water is groundwater, which supplied 28 million...
Mitigation of Non-Point Source Pollution Impacts on Groundwater Aquifers: A Case Study
This paper presents methodologies applied to a regional-scale project to study the potential impacts of storm runoff on groundwater aquifers that store sole source water supplies in Morris...
Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...
Aquifer Remediation Design: Nonlinear Programming and Genetic Algorithms
Nonlinear programming and genetic algorithm solutions of a pump-and-treat aquifer remediation design model are presented and discussed. These models find the minimum cost design of the...
