USGS technician monitoring a low flow in a stream while standing on a pebble island in stream in summer.
September 24, 2016

Data on low-flow characteristics are used by water-resources managers for a variety of purposes, including water-supply planning, making decisions about wastewater-discharge and water withdrawal permits, and evaluating in-stream flow requirements. The Michigan low-flow network currently consists of seven sites where streamflow is typically measured only during low-flow periods. In addition to...

USGS Water-Quality equipment with cover opened at edge of river near a footbridge.
September 24, 2016

The USGS operates a network of real-time water-quality monitoring stations that measure up to five physical parameters. The parameters are temperature, specific conductance, pH, dissolved oxygen, and turbidity. One to four of those parameters are measured at 26 sites, while all five parameters are measured at 13 sites. These data are used for decision making about hydroelectric power...

Tracer-based characterization of hyporheic exchange and benthic biolayers in streams

Shallow benthic biolayers at the top of the streambed are believed to be places of enhanced biogeochemical turnover within the hyporheic zone. They can be investigated by reactive stream tracer tests with tracer recordings in the streambed and in the stream channel. Common in-stream measurements of such reactive tracers cannot localize where the...

Potentially exploitable supercritical geothermal resources in the ductile crust

The hypothesis that the brittle–ductile transition (BDT) drastically reduces permeability implies that potentially exploitable geothermal resources (permeability >10−16 m2) consisting of supercritical water could occur only in rocks with unusually high transition temperatures such as basalt. However, tensile fracturing is possible even in...

Acetylene fuels TCE reductive dechlorination by defined Dehalococcoides/Pelobacter consortia

Acetylene (C2H2) can be generated in contaminated groundwater sites as a consequence of chemical degradation of trichloroethene (TCE) by in situ minerals, and C2H2 is known to inhibit bacterial dechlorination. In this study, we show that while high C2H2 (1.3 mM) concentrations reversibly inhibit reductive dechlorination of TCE by Dehalococcoides...
