What is petroleum contamination?
“Subsurface contamination by petroleum hydrocarbons is one of the most common forms of pollution in modern society. It is caused by fuel, oil and gas leaks and spills and commonly occurs around industrial sites where these products have long been used or stored.
What does petroleum do to soil?
Soils contaminated by petroleum hydrocarbons can affect soil health. And it can do so at much lower concentrations compared to the effects on human health. These types of petroleum products can clog the soil so that water and air is difficult to move to plant roots, resulting in drought-like symptoms.
What is soil contamination?
Soil contamination occurs when human-made chemicals, such as hydrocarbons and heavy metals, find their way into the earth, altering the natural soil environment. Generally, soil contamination is cited as a consequence of non-organic farming practises, industrial activity and improper waste disposal.
How is petroleum contaminated soil treated?
Washing with organic solvents such as ethanol- water mixture and ethyl acetate-acetone-water mixture exhibited significant removal of hydrocarbons from the contaminated soil [18-20]. Soil washing does not only treat the oil contaminated soil but also remove the heavy metals from the soil.
How does soil get contaminated?
In urban areas, soil contamination is largely caused by human activities. Some examples are manufacturing, industrial dumping, land development, local waste disposal, and excessive pesticide or fertilizer use. When soil is contaminated with these substances, it can hurt the native environment.
What causes contaminated soil?
What happens if soil is contaminated?
If your soil is contaminated, there’s a chance that the toxic materials can be absorbed into the plants you’re growing. These chemicals are detrimental to soil health and could damage, or even kill, the plants you’re growing.
How do you dispose of contaminated soil?
Evacuation and Proper Disposal. The quickest and possibly simplest method of reducing the amount of petroleum-contaminated soil is by excavating the contaminated soil and shipping it to an appropriate landfill for disposal or to a facility where the contaminated soil can be incorporated into paving material.
Why is contaminated soil a problem?
Contaminated soils can leach toxic chemicals into nearby ground or surface waters, where these materials can be taken up by plants and animals, contaminate a human drinking water supply, or volatilize and contaminate the indoor air in overlying buildings.
What are the pollutants that contaminate soil?

- Lead (Pb)
- Mercury (Hg)
- Arsenic (As)
- Copper (Cu)
- Zinc (Zn)
- Nickel (Ni)
- PAHs (polyaromatic hydrocarbons)
- Herbicides/Insecticides.
What is done with contaminated 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 …
When is soil contaminated with petroleum products not hazardous waste?
1. Contaminated soil resulting from a petroleum storage tank release or from a spill qualifies for an exemption from the limits and/or testing specified in subdivisions D 2 a, b, and c of this section where the total volume of contaminated soil from a cleanup site is less than 20 cubic yards, and the contaminated soil is not a hazardous waste. 2.
What is the TC rule for petroleum contaminated soil?
The Toxicity Characteristic (TC) Rule identifies benzene and lead as compounds which may cause petroleum-contaminated waste to be hazardous. Analysis of additional parameters may be necessary for petroleum-contaminated soil located at sites where other contaminants may be present.
What is 9vac20-81-660 soil contaminated with petroleum products?
