Which of the following is a common method for removing contaminants from soil?

  1. Phytoremediation

  2. Incineration

  3. Landfilling

  4. Vitrification


Correct Option: A
Explanation:

Phytoremediation is a process that uses plants to absorb and break down contaminants from soil.

What is the process of removing contaminants from groundwater called?

  1. Bioremediation

  2. Pump-and-treat

  3. Air stripping

  4. Soil vapor extraction


Correct Option: B
Explanation:

Pump-and-treat is a process that involves pumping contaminated groundwater to the surface, treating it, and then reinjecting it into the aquifer.

Which of the following is a common method for removing contaminants from air?

  1. Scrubbing

  2. Filtration

  3. Adsorption

  4. Condensation


Correct Option: A
Explanation:

Scrubbing is a process that involves passing contaminated air through a liquid or solid medium to remove contaminants.

What is the process of removing contaminants from solid waste called?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Composting


Correct Option: A
Explanation:

Incineration is a process that involves burning solid waste at high temperatures to destroy contaminants.

Which of the following is a common method for removing contaminants from hazardous waste?

  1. Stabilization

  2. Solidification

  3. Encapsulation

  4. Vitrification


Correct Option: A
Explanation:

Stabilization is a process that involves chemically treating hazardous waste to reduce its toxicity and mobility.

What is the process of removing contaminants from a site called?

  1. Remediation

  2. Restoration

  3. Reclamation

  4. Revitalization


Correct Option: A
Explanation:

Remediation is the process of removing contaminants from a site to make it safe for human health and the environment.

Which of the following is a common type of remediation technology?

  1. Excavation

  2. Pump-and-treat

  3. In situ treatment

  4. Bioremediation


Correct Option: A
Explanation:

Excavation is a process that involves digging up contaminated soil or groundwater and removing it from the site.

What is the process of using microorganisms to break down contaminants called?

  1. Bioremediation

  2. Phytoremediation

  3. Mycoremediation

  4. Zoremediation


Correct Option: A
Explanation:

Bioremediation is a process that uses microorganisms to break down contaminants into harmless substances.

Which of the following is a common type of in situ treatment technology?

  1. Soil vapor extraction

  2. Air sparging

  3. Bioventing

  4. Permeable reactive barriers


Correct Option: A
Explanation:

Soil vapor extraction is a process that involves removing contaminants from soil by applying a vacuum to the soil.

What is the process of using plants to absorb and break down contaminants called?

  1. Phytoremediation

  2. Phytoextraction

  3. Rhizofiltration

  4. Phytostabilization


Correct Option: A
Explanation:

Phytoremediation is a process that uses plants to absorb and break down contaminants from soil, water, and air.

Which of the following is a common type of phytoremediation technology?

  1. Landfarming

  2. Constructed wetlands

  3. Green roofs

  4. Phytoremediation walls


Correct Option: A
Explanation:

Landfarming is a process that involves spreading contaminated soil over a large area and allowing plants to grow on it.

What is the process of using fungi to break down contaminants called?

  1. Mycoremediation

  2. Fungal bioremediation

  3. Mycofiltration

  4. Mycorestoration


Correct Option: A
Explanation:

Mycoremediation is a process that uses fungi to break down contaminants into harmless substances.

Which of the following is a common type of mycoremediation technology?

  1. Fungal bioremediation of soil

  2. Fungal bioremediation of water

  3. Fungal bioremediation of air

  4. Fungal bioremediation of hazardous waste


Correct Option: A
Explanation:

Fungal bioremediation of soil is a process that involves using fungi to break down contaminants in soil.

What is the process of using zero-valent iron to break down contaminants called?

  1. Zoremediation

  2. Iron remediation

  3. Zero-valent iron treatment

  4. Iron-based remediation


Correct Option: A
Explanation:

Zoremediation is a process that uses zero-valent iron to break down contaminants into harmless substances.

Which of the following is a common type of zoremediation technology?

  1. Permeable reactive barriers

  2. In situ chemical reduction

  3. Groundwater treatment

  4. Soil remediation


Correct Option: A
Explanation:

Permeable reactive barriers are a type of zoremediation technology that involves installing a wall of zero-valent iron in the ground to intercept and treat contaminated groundwater.
