4 Types of Environmental Remediation

Environmental contamination is a health threat to the natural flora and fauna of the area as well as to humans. Fortunately, there are many types of environmental remediation to remove or clean up contaminated groundwater, surface water and soil. The first step in a remediation project is a site assessment to determine the extent and type of contamination. Depending on the site geology, cofferdam installation Syracuse NY may be employed to pump water out of the affected area, allowing access to the contaminated soil as well as keeping contaminated water isolated so that it may be treated.

An overview on Various Categories of Environmental Remediation ...

1. Excavation

One of the most common types of remediation is excavation. Contaminated soil is simply removed from the site and either transported to a landfill for disposal or treated for the particular contaminant that is present.

2. Pump and Treat

A second very common approach is pump and treat. Mostly used for contaminated groundwater, this method pumps contaminated water out of the environment and either treats the water directly or pumps it into a holding tank to be treated at a later time.

3. Soil Vapor Extraction

Soil vapor extraction relies on the vapor pressure difference between soil and a contaminant, especially volatile organic compounds such as gasoline, solvents and pesticides. A vacuum pump is applied to remove the vapor, which can be treated or eliminated.

4. Bioremediation

Bioremediation can involve the introduction of microorganisms to a contaminated site or altering the environmental conditions of the site to enhance the natural growth of beneficial microorganisms. In either case, remediation is achieved through a natural break-down of a contaminant by the organism, which can be bacteria, fungi or plants.

While it may seem that cleaning up environmental pollution is an insurmountable task, there are many effective techniques for remediation, often utilizing natural materials to minimize environmental impact.
