Contaminated soil treatment

Introduction

Soil pollution is when humans introduce harmful objects, chemicals or substances, directly or indirectly into the soil in a way that causes harm to other living things or destroys soil or water ecosystems. Soil pollution is often considered as a hidden danger, because it is a kind of pollution that is not easily visible to the eye, although its effects can be catastrophic.

Soil contamination is when the concentration of chemicals, nutrients or elements in the soil becomes more than it normally or naturally is, as a result of human action. If this contamination goes on to harm living organisms, we can call it pollution.

Types of contaminated soil

Relocation sites of petrochemical plants, coking plants, iron and steel plants, pesticide plants and gas stations in cities, surrounding pollution caused by solid waste accumulation and dust ball deposition in mining, soil pollution caused by urban informal waste, and many other reasons have resulted in a large number of sites polluted by residual organic matter, heavy metals and combined pollution of organic matter and heavy metals. Harmful and serious substances in soil exceed the self-purification ability of soil, resulting in physical, chemical and biological changes of soil and endangering human health.
After the change of such polluted land into public land such as residential, commercial, school, medical and so on, people living on this land are seriously affected. Therefore, it is necessary to restore such polluted land before using it.

What causes contamination?

Pesticides and herbicides (and other farming chemicals) often end up contamination soils. Direct discharge of wastewater by industries can also cause that. Leakages in sewage systems, underground storage tanks and leaching of soluble substances from landfills can also result in contamination. Rainwater or floods from other polluted lands and water bodies spread contaminants to soils in other locations.

The effects of soils contamination

Soil contamination can result in soil and land pollution, and affect the health of plants that depend on them. It can also harm living organisms in the soils and humans that come into contact with them by touching, breathing or eating crops from contaminated soils. Contaminants in soils can also get infiltrated into ground water and pollute them.

Depending on the extent and volume of soil contamination, it can be remedied by

Incineration

Oxidative removal of organic pollutants through aerobic combustion.

Landfill

Entering the landfill site for landfill.

Curing/stabilization

The process of curing/stabilizing contaminated soil in a manner that does not harm the environment.(such as vitrification, and then buried deep).
