e I Environmental Site Assessment report. Which is why site assessment is such a crucial factor in environmental remediation. Make no mistake [link widoczny dla zalogowanych], this is rocket science, and it is essential if you want mankind to be able to keep pollution at a bare minimum.The different remediation technologies include dredging or excavation, SEA (surfactant enhance aquifer remediation), pump and treat [link widoczny dla zalogowanych], solidification and stabilization, in situ oxidation, and soil vapor extraction. Let's discuss each in more detail.1. Dredging or ExcavationDredging is the process of hauling and transferring the contaminated soil from an unregulated site to a regulated landfill—it's exactly what its name says it is. But on the other hand dredging can also mean simply aerating the contaminated material in the case of VOCs (volatile organic compounds). Recent technology developments [link widoczny dla zalogowanych], however, allows remediators to remediate VOCs on-site and no longer have to haul them off somewhere to a regulated area.2. SEAR - Surfactant Enhanced Aquifer RemediationThe Surfactant Enhanced Aquifer Remediation is the process of injecting specialty surfactants or hydrocarbon mitigation agents into the subsurface of the contaminated material. What it does is improve the desorption of N
