This is a fundamental study of the mechanism of protein particle
removal during flow through sandy soil. Mathematical models for
diffusion-adsorption and diffusion-convection-adsorption processes
were developed and compared with experimental data....

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...

A method was developed for assessing the vulnerability
of groundwater to contamination from contaminant sources
at the soil surface, using a numerical groundwater flow
model linked to a digital map database. The method was
applied using the...
