Article
Full-text available
Understanding a community's concerns and informational needs is crucial to conducting and improving environmental health research and literacy initiatives. We hypothesized that analysis of community inquiries over time at a legacy mining site would be an effective method for assessing environmental health literacy efforts and determining whether co...
Article
Full-text available
A research project that is only expert-driven may ignore the role of local knowledge in research, give low priority to the development of a comprehensive communication strategy to engage the community, and may not deliver the results of the study to the community in an effective way. To demonstrate how a research program can respond to a community...
Article
Biochar from pine forest waste (PFW) was used in greenhouse pot experiments to evaluate plant growth using two levels (2% and 4% wt/wt) of biochar amendments applied to an alkaline, loamy sand soil. Biochar soil additions induced a large decrease in the soil bulk density (from 1.59 to 1.26 g cm−3) and large to moderate increases in gravimetric and...
Article
Abstract: The objective of this research was to examine the potential for intercalation of trichloroethene (TCE) by clay minerals associated with aquifer sediments. Sediment samples were collected from a field site in Tucson, AZ. Two widely used Montmorillonite specimen clays were employed as controls. X-ray diffraction, conducted with a controlled...
Poster
Pump-and-treat systems are widely used to remediate hazardous waste sites wherein groundwater is contaminated by compounds such as TCE (trichloroethene). It is well known that removal of contaminant mass by pump and treat becomes less effective over time, with a persistent mass discharge causing greatly extended operational periods. One mechanism p...
Article
In response to the need for improved agricultural best management practices in irrigated lands, the GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) model was modified to include a component that models furrow, basin, and border irrigation practices. The irrigation component of the new model, GLEAMS-IR, was validated with res...
Article
Langbeinite is a soluble potassium‐magnesium sulfate mineral (K2SO42MgSO4) found as an evaporite in many regions of the world. Langbeinite was used as a reclaiming material in a fine textured (clay loam) saline sodic soil (Grabe Series). This amendment can be dissolved and directly into the irrigation water, displacing sodium (Na) quickly with mini...
Chapter
The sorption and transport of Cd, Ni, and Sr in two subsurface soils (Hayhook series and Borden) were investigated using batch and miscible displacement experiments. The sorption isotherms of Cd, Ni, and Sr were strongly nonlinear and well described by the Freundlich equation (S = KFCnFCnF). Electrostatic adsorption was found to be the major contri...
Article
A statistical comparison of data collected from two cotton production fields with a history of either commercial fertilizer or sludge amendments showed significantly different nitrate‐nitrogen (N) concentrations in time and space. The sludge‐amended field had high nitrate concentrations in the root zone (1.5 m) throughout the season. Whereas, the f...
Article
Complexation of cadmium, lead, and zinc (singly and in a mixture) by a monorhamnolipid biosurfactant produced by Pseudomonas aeruginosa ATCC 9027 was studied in batch solution and soil experiments. Conditional stability constants (log K-L) for metal-rhamnolipid complexation in a buffered medium (0.1 M Pipes, pH 6.8) were determined in duplicate usi...
Article
The potential of microbially-produced surfactants (biosurfactants) to complex heavy metals was investigated in this study. Batch solution studies using a model metal, cadmium, and an anionic monorhamnolipid biosurfactant produced by Pseudomonas aeruginosa ATCC 9027 showed that complexation of the metal and biosurfactant was rapid and stable and ach...
Article
A useful extraction for humic acid from anaerobic municipal solid-waste landfill leachate is presented. Extraction was accomplished by adding NaOH pellets to give a 0.57N NaOH solution under an N2 atmosphere. The separation of the humid and fulvic acid fractions was carried out using Matricel type filters (0.45-µm pore size diam). The infrared char...
