Land Pollution is the deterioration (destruction) of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.
It occurs when waste is not disposed of properly, or can occur when humans throw chemicals onto the soil in the form of pesticides, insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface.
- One gallon of oil can pollute 4 acres of soil
- One gallon of paint can pollute 1 acre of soil
- One gallon of gasoline can pollute 3 acres of soil
- One gallon of road salt can pollute 48/3125 acres of soil
- One ton of salt can pollute 8/5 acres of soil
Soil pollution can be caused by the following (non-exhaustive list!):
- Oil drilling
- Mining and activities by other heavy industries
- Accidental spills as may happen during activities, etc.
- Corrosion of underground storage tanks (including piping used to transmit the contents)
- Acid rain (in turn caused by air pollution)
- Intensive farming
- Agrochemicals, such as pesticides, herbicides and fertilizers
- Industrial accidents
- Road debris
- Drainage of contaminated surface water into the soil
- Waste disposal
- Oil and fuel dumping
- Nuclear wastes
- Direct discharge of industrial wastes to the soil
- Landfill and illegal dumping
