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.
