The toxicity of selected gasoline components to glucose methanogenesis by aquifer microorganisms
Six model hydrocarbons, representing various classes of chemicals found in gasoline, and methyl ethyl ketone, were assayed for their inhibitory effect on glucose methanogenesis in slurries prepared from aquifer sediments and ground water. Biogas (CH4and CO2) production was monitored with an automated pressure transducer system. Benzene, 1-methyl naphthalene, and methyltert-butyl ether (MTBE) were

Concentrations and loads of selected trace elements and other constituents in the Rio Grande in the vicinity of Albuquerque, New Mexico, 1994
The Pueblo of Isleta and the New Mexico Environment Department
have established water-quality standards for the Rio Grande,
which flows through Albuquerque, New Mexico. Trace-element
concentrations historically have been greater than maximum
permissible concentrations allowed by these standards. It is not
known if these concentrations are due to sources from the
Albuquerque metropolita

Hydrology and geochemistry of aquifer and stream contamination related to acidic water in Pinal Creek basin near Globe, Arizona
Hydrologic and geochemical research has identified and characterized the physical and chemical processes that control the evolution and movement of metal contaminants in ground water beneath Miami Wash and lower Pinal Creek. The dissolution of calcite in the alluvial aquifer has slowed and neutralized part of the acidic plume, and the sorption of some metals such as nickel and copper to other soli

Laboratory and quality assurance protocols for the analysis of herbicides in ground water from the Management Systems Evaluation Area, Princeton, Minnesota
Laboratory and quality assurance procedures for the analysis of ground-water samples for herbicides at the Management Systems Evaluation Area near Princeton, Minnesota are described. The target herbicides include atrazine, de-ethylatrazine, de-isopropylatrazine, metribuzin, alachlor, 2,6-diethylaniline, and metolachlor. The analytical techniques used are solid-phase extraction, and analysis by gas

Temporal changes in the configuration of the water table in the vicinity of the management systems evaluation area site, central Nebraska
To improve understanding of the hydrologic characteristics of the shallow aquifer in the vicinity of the Management Systems Evaluation Area site near Shelton, Nebraska, water levels were measured in approximately 130 observation wells in both June and September 1991. Two water-table maps and a water-level-change map were drawn on the basis of these measurements. In addition, historical data from U

Factors affecting tritium and 14carbon distributions in the unsaturated zone near the low-level radioactive-waste burial site south of Beatty, Nevada
Interpretations of the distributions of tritiated water vapor (HTOV) and 14carbon dioxide gas (14CO2) concentrations in the unsaturated zone adjacent to the low-level radioactive-waste burial site south of Beatty, Nevada, suggest that observed concentrations of 14CO2 could be explained by either diffusive or advective transport of the radioactive gas from the site.The distribution of HTOV cannot b
