In situ soil vapour extraction. Volatile and some semi-volatile organic compounds (VOCs and Semi-VOCs) can be removed from unsaturated soils by a process known as soil vapour extraction (SVE).
SVE as an in situ clean-up process allows contaminated soil to be remediated without disturbance or excavation (Nadim et al. ).Cited by: Bioremediation is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants.
In many cases, bioremediation is less expensive and more sustainable than other remediation alternatives. Bioremediation is the process of harnessing the natural occurrence that depends on the microbes to go about their regular life processes.
These processes include metabolic pathways that utilize these toxins as a source of energy and convert them into non-toxic substances like ethylene and chloride. Bioremediation, like any technology applied to clean up a contaminated site, must first be approved by government regulators who ultimately must agree that the technology has a reasonable chance to reduce the contaminant(s) at the site to acceptable levels.
