Soil corrosion refers to complex chemical reactions with certain elements that occur in soils. For instance, variables in soil characteristics and properties can have a huge impact on the corrosion activity that occurs in buried structures. Soil corrosion usually takes place with storage tanks that are stored under the ground, cables, foundations, and distribution and transmission pipelines and waterlines. Any structures that are in contact with earth are considered prone to the damaging effects of soil corrosion. Metals that are in contact with materials such as soil can develop a corrosion potential. Thus, the mechanism of soil corrosion should be known, along with the strategies that should be implemented to avoid or mitigate the corrosion of metal when it comes in contact with soil.
