Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

A numerical model for the fate and transport of chlorinated phenols in groundwater

Creator:: Lee, Sang Bong
Abstract:: The objective of this study was to develop a numerical model for the movement and fate of chlorinated phenols in groundwater. In the first part, a numerical model for several different equilibrium and nonequilibrium sorption processes under isothermal conditions is developed for one-dimensional, steady-state water flow in soil columns. The...

Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

Creator:: Cole, Jason David
Abstract:: A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

Groundwater flow model for the lower Malheur Basin near Ontario, Oregon

Creator:: Walker, David S.
Abstract:: The shallow, poorly-confined, sand and gravel aquifer underlying the lower Malheur River basin is contaminated by nitrate and metabolites of the herbicide dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985, respectively. The aquifer supplies water for the Ontario municipal water system, domestic and industrial uses, and irrigation. In response...

Radon-222 as an indicator for nonaqueous phase liquids in the saturated zone : developing a detection technology

Creator:: Hopkins, Omar Snowden
Abstract:: Radon-222 gas has unique properties allowing it to be used as an indicator for the presence of organic phase liquids in the saturated zone. It naturally occurs in soils. It is radioactive, making quantitative detection straight forward. A noble gas, it is chemically inert and does not react with aquifer...

Nitrate and pesticide transport under pear production in clay and sandy soil

Creator:: Cao, Weidong
Abstract:: Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...

Down-borehole permeable barrier reactor : primary substrate selection for aerobic dichlorophenol degradation

Creator:: Kaslik, Peter J.
Abstract:: In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary substrate for dichlorophenol cometabolism. Serum bottle tests comparing the effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed phenol to be the most effective followed by imitation vanilla flavoring,...
