What are the 2 types of groundwater remediation and how are they different from each other?
There are two types of groundwater remediation: in situ (in place or on-site) and ex situ (off-site). The in-situ remediation approach involves cleaning the water where it is presently situated, rather than removing and transferring it elsewhere.
How do you remediate contaminated groundwater?
The most basic type of groundwater remediation, uses air to strip water clean (air sparging). Another method, called pump and treat, physically removes the water from the ground and treats it by way of biological or chemical means. Both of these methods have proven successful in treating contaminated groundwater.
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 are water remediation techniques?
Remediation techniques which have been commonly used include: containment, pump-and-treat, extraction, stabilization/solidification, soil washing, air stripping, precipitation, vitrification, thermal desorption and biological remediation.
What are remediation techniques?
Remediation techniques play a key role in fully cleaning up the contaminants in soils and groundwater. Techniques frequently used are: containment, pump-and-treat, extraction, stabilization/solidification, soil washing, air stripping, precipitation, vitrification, thermal desorption, and bioremediation.
What are the types of remediation?
Soil Remediation You can do it using natural means, such as using certain types of bacteria. Additionally, thermal soil remediation, air sparging, and encapsulation may be effective. The most immediate type of remediation is removal of the contaminated soil and replacement with clean fill.
What is ex situ remediation?
Ex situ remediation includes excavation of contaminated soil, which is then transported to a special landfill, where one of the appropriate forms of remediation is performed.
What is another word for remediation?
decontamination, sanitation, rehabilitation, restoration, remedial, reclamation, reorganisation, cleanup, clean-up, ‘assainissement, regeneration, abatement, correction.
