To increase the operating lifetime of landfills and to lower leachate treatment costs, an increasing number of municipal solid waste (MSW) landfills are being managed as either aerobic or anaerobic bioreactors. Landfill gas composition, respiration r

Pilot-scale tests for the land disposal of Se-enriched sediments from the San Luis Drain were performed in the San Joaquin Valley, California. Three test plots were instrumented and monitored on a dirt-road embankment near the sediment source area, p

Research in a San Francisco Bay intertidal marsh has shown the accumulation of Se and trace metals (Cu, Ni, Zn, Pb, Cd, Fe) on bagged litter of five common estuarine marsh plant species, over periods of months to a year. Metal concentrations increase

A conceptual model of the geometry and physics of water flow in a fractured basalt vadose zone was developed based on the results of lithological studies and a series of ponded infiltration tests conducted at the Box Canyon site near the Idaho Nation

Selenium stable isotope ratios can serve as indicators of Se sources and reduction of Se oxyanions, much as sulfur and nitrogen isotope ratios do in sulfur and nitrogen biogeochemical studies. A new analytical method, which allows precise Se isotope

Selenium stable isotope ratio measurements should serve as indicators of sources and biogeochemical transformations of Se. We report measurements of Se isotope fractionation during selenate reduction, selenite sorption, oxidation of reduced Se in soi

In an effort to enhance the usefulness of neutron logging for environmental applications, a new combination of backfill and casing materials for access boreholes has been developed. The combination of acrylic casing and polyurethane foam backfill has

Near‐surface environmental investigations often require monitoring of the spatial distribution of water content and identification of preferential fluid flow paths. Water content estimates are needed, for example, to model and predict pollutant tra

The speciation and association of Se in soil determines its availability to biota. Oxidized forms are generally more biologically available. Surface and subsurface soils from Se-contaminated Kesterson Reservoir were incubated for 2.5 yr at temperatur

Two approaches were taken to estimate evaporation of water from the surface of a salt-encrusted and Se contaminated soil in a playalike environment at Kesterson Reservoir, California. Direct evaporation flux measurements were made using a lysimetric
