What is the difference between remediation and mitigation?
Remediation and Mitigation Explained Remediation occurs when the threat can be eradicated. Mitigation is more like damage control; the issue cannot be eliminated immediately but it can be minimized. For example, the hijacking of a DNS server could lead to significant damage in a very short amount of time.
What types of technologies can be used for site remediation and how do they work?
EXTRACTION TECHNOLOGIES Two technologies commonly used for source remediation work primarily by physically extracting the contaminants from the subsurface. Multiphase extraction employs a vacuum or pump to extract NAPL, vapor, and aqueous phase contaminants, which may then be disposed of or treated.
How do you remediate a lesson?

Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater. … In this process, chemical compounds produced by the plant immobilize contaminants, rather than degrade them.
What is remediation engineering?What is an Environmental Remediation Engineer. Environmental remediation is the process of reducing radiation exposure from the environment, particularly the soil and water. … After the remediation process begins, the environmental remediation engineer is also in charge of overseeing the project from start to finish.
Article first time published onWhat is remediation in environmental science?
Environmental remediation is the removal of pollution or contaminants from water (both ground water and surface water) and soil. These waste products are removed for the protection of human health, as well as to restore the environment.
Why is environmental remediation important?
Environmental remediation refers to reducing radiation exposure, for example, from contaminated soil, groundwater or surface water. The purpose is more than just eliminating radiation sources; it is about protecting people and the environment against potential harmful effects from exposure to ionizing radiation.
Which of the following technique is successful in treating petroleum hydrocarbons?
9. Which of the following technique is successful in treating petroleum hydrocarbons? Explanation: Landfarming is an above-ground remediation technology that reduces the concentration of petroleum constituents present in soils through processes associated with bioremediation.
What is in-situ remediation?
In-situ remediation is a method of breaking down and purifying hazardous substances present in soil and groundwater. … It is a method that has little environmental impact, with no need to remove and transfer contaminated soil.
What is remediation in cyber security?
Remediation in cyber security refers to the addressing a breach and limiting the amount of damage that breach can potentially cause to your business. If you fail to notice and act upon a breach in time, it can grow so big that it becomes almost impossible to contain it.
What is remediation in vulnerability management?
Once a vulnerability has been discovered, the ideal solution is to remediate it—to fix or patch the vulnerability before it can become a security threat. … Remediation can be as simple as applying a readily available software patch or as complex as replacing a fleet of physical servers across an organization’s network.
What is a remedial plan?
A Remedial Action Plan, or Remediation Plan is a guideline that proposes a series of engineering and geological procedures, in order to feasibly perform contamination cleanup actions over a strategic period of time. … Environmental professionals, such as geologists and engineers, typically prepare these guidelines.
What is remediation teaching?
At a basic level, remediation (or reteaching) means “teaching again” content that students previously failed to learn. … Many teachers engage in remediation regularly as a natural part of instruction, without using a formal process or even explicitly recognizing their actions as intentional reteaching.
What is remediation and intervention?
Intervention is typically used to target specific learning disabilities and is thus tailored for each individual student. … Remediation is also colloquially known as “re-teaching,” as it assumes that the student has been introduced to concepts previously but has not yet mastered them.
Which of the following technique is used to remediate contamination at the boundary level of water table?
Explanation: Biosparging is the technique which is used to re-mediate contamination at the boundary level of water table, Bio-magnification is the process by which toxic substances get deposited in the food chain, Immobilization uses Bio-accumulation processes, bio-degradation is the process that leads to degradation …
What is the major focus of remediation strategy for natural gas?
Green Remediation Strategy: The strategy’s primary focus is reduction of greenhouse gas (GHG) generation, as part of compliance with the U.S. Department of Defense Consideration of Green and Sustainable Remediation Practices in the Defense Environmental Restoration Program guidance.
What techniques are used in the United States to clean contaminated water air and soil?
The main methods used include: containment, soil washing, thermal treatment, vapor extraction, bio-remediation, incineration, and other physical/chemical treatments.
What are the three types of phytoremediation?
There are five basic types of phytoremediation techniques: 1) rhizofiltration, a water remediation technique involving the uptake of contaminants by plant roots; 2) phytoextraction, a soil technique involving uptake from soil, 3) phytotransformation, applicable to both soil and water, involving the degradation of …

What is phytoremediation example?
Phytoremediation is defined as the use of green plants, including grasses and woody species, to address environmental contamination by heavy metals, metalloids, trace elements, organic compounds and radioactive compounds in soil or water [24].
What are the important data required for planning contaminated site remediation?
Broadly, site characterization or contaminated site assessment (CSA) is important for: a) Determining concentration and spatial distribution of harmful pollutants under consideration. b) Determining the extent of site remediation (zonation) based on which the suitable remediation technique is selected.
What tools do environmentalists use?
Environmental Scientists use a variety of tools including ambient air samplers, biological and water sampling equipment, chemical analysis equipment, computers, industrial emission monitors, radiation detectors, and traffic monitors.

Choosing the most effective remediation systems. Preparing reports to communicate findings.
What is remediation of soil?
Soil remediation, is a phrase that refers to different procedures designed to remove contaminants such as hydrocarbons, heavy metals, pesticides, cyanides, volatiles, creosote, and semi volatiles from dirt.
