What is VCUP?
The Voluntary Cleanup and Redevelopment Program was created in 1994 to facilitate the redevelopment and transfer of contaminated properties.
What is the clean up procedure for contaminated soil?
The main methods used include: containment, soil washing, thermal treatment, vapor extraction, bio-remediation, incineration, and other physical/chemical treatments.
What are the classes of soil remediation?
Traditionally, there are three main soil remediation technologies: soil washing, bioremediation and thermal desorption. Soil washing is a process that uses surfactants and water to remove contaminants from the soil.
Why is soil remediation required?
Soil remediation is required to clean and maintain top quality criteria of dirt, water and air that may consequently advantage commercial cultivation, and wild flora and fauna.
Who is responsible for cleaning up brownfields?
EPA
EPA conducts and supervises investigation and cleanup actions at sites where oil or hazardous chemicals have been or may be released into the environment. Cleanup activities take place at active and abandoned waste sites, federal facilities and properties, and where any storage tanks have leaked.
What is considered contaminated soil?
Soil contamination occurs when hazardous chemicals are buried or spilled or have migrated into uncontaminated soil. Contamination can take place during improper disposal of hazardous chemicals, during the application of pesticides and fertilizers, or through chemical and industrial processes.
How can you tell if soil is contaminated?
Apparent discolorations in soil and strong odors are other indications that the soil may be hazardous. Another possible clue of contamination may be if vegetation fails to thrive in a certain area of soil, although this depends on the vegetation and whether the soil’s natural content is hospitable to such growth.
What are the 3 types of remediation that occur?
The main three types of environmental remediation and reclamation
- Soil remediation. There are many factors that affect the soil condition.
- Groundwater and Surface water remediation.
- Sediment remediation.
- Sources.
How much does it cost to clean soil?

Can you clean polluted soil?
According to the EPA, “Treatment approaches can include: flushing contaminants out of the soil using water, chemical solvents, or air; destroying the contaminants by incineration; encouraging natural organisms in the soil to break them down; or adding material to the soil to encapsulate the contaminants and prevent …
Who cleans up the oil spill?
In the United States, the Coast Guard and the Environmental Protection Agency are two agencies that are responsible for cleaning up oil spills. When an oil spill occurs, the oil floats and forms a millimeter-thick layer on the surface of the water.
When should a soil sample be collected at the soil-groundwater interface?
If a soil sample is collected at the soil-groundwater interface and is above the 500 mg/kg threshold limit, submerged soils should be collected until the soil is fully defined to 500 mg/kg. During the remediation phase, the continued analysis of TPH in groundwater should be evaluated on a site-specific basis.
Where do I find protection of groundwater SSLs in Colorado?

What is the “resident soil” column in the EPA RSL summary table?
We will continue to use the “Resident Soil” and “Industrial Soil” sub-columns within the main “Screening Levels” column of the EPA RSL Summary Table as screening levels to determine whether levels of soil contamination at a site warrant further investigation or cleanup.
