Better estimates of non-aqueous phase liquid (NAPL) mass, its persistence into the future, and the potential impact of source reduction are critical needs for determining the optimal path to clean up sites impacted by NAPLs. One impediment to constra

To assess the effects of community structure on the stability of denitrification, six chemostat cultures derived from the same denitrifying community were subjected to step increases in feed nitrate concentration and monitored for evidence that denit

We present a travel-time based reactive transport model to simulate an in-situ bioremediation experiment for demonstrating enhanced bioreduction of uranium(VI). The model considers aquatic equilibrium chemistry of uranium and other groundwater consti

A field experiment at the Oak Ridge Field Research Center has demonstrated the in situ biostimulation of U(VI) reduction with ethanol amendment, but little is known about the stimulated metabolic pathways or composition of the bacterial community med

Groundwater near the S3 ponds at the US Department of Energy's Y-12 site in Oak Ridge, Tennessee, is contaminated by high levels of nitrate (up to 160 mM) and U(VI) (∼0.3 mM). To minimize nitrate inhibition, the authors proposed extraction of conta

Ferrous iron [Fe(II)] reductively transforms heavy metals in contaminated groundwater, and the bacterial reduction of indigenous ferric iron [Fe(III)] to Fe(II) has been proposed as a means of establishing redox reactive barriers in the subsurface. T

At former Williams Air Force Base, the Air Force conducted a pilot test of thermally enhanced extraction (TEE) to reduce the mass and longevity of a multi-component NAPL fuel source in the saturated zone. Before and after the pilot test, novel tools

The stimulation of microbial U(VI) reduction is currently being investigated as a means to reduce uranium's mobility in groundwater, but little is known about the concentration at which U(VI) might inhibit microbial activity, or the effect of U(VI) o

Understanding the relationship between microbial community dynamics and functional instability is an important step towards designing reliable biological water treatment systems. In this study, the community dynamics of two dispersed-growth denitrify
