What’ll They Think of Next? Dewatering Contaminated Slurries Using Geotextile Tubes
Sediment must be dredged from the bottom of waterbodies to maintain their capacity and navigability. Dredging, by its nature, involves the removal of highwater-content slurries and also helps preserve...
Sediment Pollution: Solving "Rill" Problems Using RECPs
Sediment pollution causes an estimated $16 billion in environmental damage annually. Sediment is the most common pollutant in rivers, streams, lakes, and reservoirs, causing such negative effects as temperature...

Watershed-Based Permitting — A Myth or Reality?
The United States Environmental Protection Agency has promulgated the Total Maximum Daily Load process to achieve the goals of the Clean Water Act. The TMDL processis applied to water...
Mapping Aquifer Zones Based on Microbial Ecology and Geochemistry in a Landfill Leachate Plume with a Self Organizing Map
We implemented a self-organizing map to delineate aqueous geochemistry and microbial ecology in landfill leachate. In subsurface ecosystems microorganisms mitigate a myriad of chemical...
Incorporating Site Characterization Data into Contaminant Concentration Interpolations for Long-Term Monitoring Optimization
Long – term monitoring (LTM) networks are installed for groundwater remediation systems to evaluate the performance of various remediation processes and to track the variation of contaminant...
Remediation System Optimization with Alternatives
This work applies the enhanced multi-objective robust genetic algorithm (EMRGA) (Beckford and Chan Hilton, 2004) to Fort Ord's Site OU2 for optimal groundwater remediation under uncertainty....
Domestic-Well Water-Quality Data and Reports for the Environmental Public Health Tracking Network: USGS and CDC Collaboration
The mission of the Environmental Public Health Tracking (EPHT) Program is to provide information from a nationwide network of integrated health and environmental data that drive actions...
Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....
Asphalt Parking Lot Runoff Nutrient Characterization for Eight Sites in North Carolina, USA
The objectives of this study were to characterize asphalt parking lot runoff quality and determine factors influencing nutrient concentrations and loads. Event mean concentrations (EMCs)...
A Decision Framework for Stormwater Control in Urbanized Watersheds
Historically, urban growth occurred around water bodies due to factors such as easy access to transportation, water supply, and drainage. With the expanded transportation network along...
Enhancing the Solution of Large Monitoring Network Design Problems Using a New Epsilon-Dominance Hierarchical Bayesian Optimization Algorithm
Designing long-term monitoring (LTM) networks for contaminated groundwater is a challenging problem that has long been recognized to suffer from the curse of dimensionality. LTM design...
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...
Optimal Resource Allocation for the Cleanup of Petroleum Contaminated Sites
Site rehabilitation is conducted in many states using a risk-based corrective action process wherein alternative remedial actions are evaluated and implemented, depending on the level...
Characterization of Particle Class Sizes Associated with Indicator Organisms in Stormwater
The presence of pathogen indicators is the leading cause of water body impairment in the United States, accounting for over 15% of the waters currently requiring TMDL development (USEPA,...
Drinking Water Distribution Systems: A Dual-Use Vision for Implementing an Environmental Observatory for an Engineered System
The U.S. Environmental Protection Agency (EPA), under Homeland Security Presidential Directive 7, has been tasked as the lead federal agency in protecting water infrastructure in the U.S....
