Pollution and the global health impacts from toxic environmental pollutants are presently of
great concern. At present, more than 100 million people are at risk from exposure to a …

Human activities have released large amounts of toxic organic and inorganic chemicals into
the environment. Toxic waste streams threaten dwindling drinking water supplies and impact …

Chlorinated solvents such as trichloroethene (TCE) and tetrachloroethene (PCE) are
widespread groundwater contaminants often released as dense nonaqueous phase liquids …

In the late 1970s and early 1980s, North America began to grapple with the legacy of past
disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive …

The fate and persistence of chlorinated organics in the environment have been a concern for
the past 50 years. Industrialization and extensive agricultural activities have led to the …

Experiments to assess metabolic reductive dechlorination (chlororespiration) at high
concentration levels consistent with the presence of free-phase tetrachloroethene (PCE) …

Publisher Summary This chapter focuses on field applications of in situ bioremediation of
deeper layers of soil and groundwater. In situ bioremediation of the unsaturated zone is well …

To learn more about the physiological state of Geobacter species living in subsurface
sediments, heat-sterilized sediments from a uranium-contaminated aquifer in Rifle …

The ability of bioremediation to treat a source area containing trichloroethene (TCE) present
as dense nonaqueous phase liquid (DNAPL) was assessed through a laboratory study and …

Dehalococcoides species are responsible for the reductive dehalogenation of an impressive
range of common, persistent environmental contaminants. These microorganisms are …
