Environmental Remediation Technology - The Different Types Of Remediation Technologies

Not everybody knows what environmental remediation is and what it does.
It isn't exactly what you talk to your friends about on your spare time.
And even if you do talk about it, people would just label you as boring.
But environmental remediation is a very important and timely topic that deserves more exposure.

Most importantly, it's for taking care of the natural environment.

Environmental remediation is that branch of science that deals with the cleaning of environmental media such as surface water, sediment, groundwater and soil from harmful contaminants and pollution.
Why is environmental remediation being put into practice? Because it is for the general benefit of human health.
A cleaner environment means better living for all its inhabitants, including human beings.
This is the main reason why it should attract more attention from the public. Environmental remediation involves several different technologies in practice.
Some of which are..
. 1.
Solidification / Stabilization The Solidification and stabilization method is proven to be one of the most solid and dependable technologies, though it's recently set off a number of issue related to durability and possible long term side effects. In addition, solidification and stabilization uses emits CO2, which is becoming a major hurdle for its widespread use.

o Solidification - This remediation technology involves adding reagents to the contaminated media to contain the pollutants and limit access by external agents o Stabilization - This remediation technology involves adding reagents to contaminated media in order to product constituents that are chemically stable 2.

Dredging or Excavation Dredging or excavation is one of the most basic types of remediation technologies around. Excavation is exactly what its name says it is, the simple process of hauling the contaminated media such as soil from its original site to a regulated landfill, where it is treated.

Excavation can also involve aerating the contaminated media when volatile organic compounds (VOCs) are present. 3.

Surfactant Enhanced Aquifer Remediation (SEAR) The Surfactant Enhanced Aquifer Remediation, also known as SEAR, is the process of injecting agents such as specialty surfactants or hydrocarbon mitigation into the subsurface in order to boost and enhance the recovery of recalcitrant non aqueous phase liquid or NAPL. This is an permanent and cost effective answer to contaminated sites that have been treated before using other remediation technologies but has proven ineffective.
SEAR is also a proven successful first step when utilizing other multi-faceted remediation technologies such as soil vapor extraction (SVE), bioremediation enhancement, or In situ Oxidation.
Other types of more advanced remediation technologies include pump and treat, in situ oxidation, and soil vapor extraction.
