Evaluation of a Bias Aware Ensemble Kalman Filter Using a Scaled Aquifer Transport Experiment
In this study, a bias-aware Ensemble Kalman Filter (EnKF) is applied to a scaled aquifer transport experiment (1-cm of the model equals 1-m at field scale and 1-day of model transport...

Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...

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...

Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...

Probabilistic Analysis of Long-Term Aquifer Recharge
Long-term time series of aquifer recharge and other aquifer fluxes (aquifer discharge, groundwater extraction) are essential to monitor and understand aquifer processes. This paper presents...

Modeling Fort Ord Site OU2's Remediation System Using Optimization
Fort Ord.s Site OU2 is located approximately 80 miles south of San Francisco near Monterey Bay in Monterey County, California. Fort Ord contains two landfills which were used for residential...

Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...

Water Quality Restoration of the Mammoth Cave Karst Aquifer: A Work in Progress
Over tens of thousands of years the aquatic ecosystem of the Mammoth Cave Karst Aquifer evolved in concordance with natural recharge supplied through 24,000 hectares of tall-grass prairie...

Optimization of the Aquifer Remediation Costs and Design with Pulsed Pumping
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce...
