The resulting body of polluted water within an aquifer is called a plume, with its migrating edges called plume fronts. Plumes are used to locate, map, and measure water pollution within the aquifer's total body of water, and plume fronts to determine directions and speed of the contamination's spreading in it. [3]
By 2008 the chromium plume was spreading, however, and it attracted media attention by 2011. [26] In November 2010, PG&E began offering to purchase threatened houses and property in Hinkley and to provide bottled water.

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Contamination must be treated before harmful vapors seep into buildings or reach drinking water. ... Past groundwater contamination, which once spread in a plume that extended to the Columbia ...

The spill contaminated the groundwater beneath about 2,800 addresses.
One definition for PRBs is an in situ treatment zone that passively captures a plume of contaminants and removes or breaks down the contaminants, releasing uncontaminated water. [1] The primary removal methods include: (1) sorption and precipitation , (2) chemical reaction, and (3) reactions involving biological mechanisms.
