To address the question of defining the technologies that can clean up groundwater contamination, we need to categorize the provided items into the appropriate technologies. Here are the items and their corresponding categories:

  1. Pumping contaminants out of the ground

    • Category: Extraction wells
    • Explanation: Extraction wells involve the physical removal of contaminated groundwater by pumping it out of the ground. This method is used to control the spread of contamination and to treat the extracted water.

  2. Materials that react with contaminants chemically transform them into safer, less soluble components

    • Category: Perm. reactive barriers
    • Explanation: Permanent reactive barriers are installed in the path of contaminated groundwater flow. These barriers contain materials that chemically react with the contaminants, transforming them into less harmful substances.

  3. Injection of oxygen and nutrients to promote bacterial growth

    • Category: Bioremediation
    • Explanation: Bioremediation involves the injection of oxygen and nutrients to stimulate the growth of bacteria that can naturally degrade contaminants in the groundwater. This biological process helps to clean up the contamination over time.

In summary, the technologies for cleaning up groundwater contamination are categorized as follows:

  • Extraction wells: Pumping contaminants out of the ground
  • Perm. reactive barriers: Materials that react with contaminants chemically transform them into safer, less soluble components
  • Bioremediation: Injection of oxygen and nutrients to promote bacterial growth
