Soil excavation is a process of digging soil with an aim of cleaning the soil, making trenches for water drainage and infrastructural purposes. The excavated soil may be used for treatment or for disposal in a landfill. Excavation has various advantages as it helps to unravel the harmful debris that could contaminate groundwater and also pollute the soil. Agriculture makes the back born of different economies in the world. Soil fertility is of key importance for plant growth and development. When a soil is contaminated, agriculture is affected negatively and hence affect productivity of a nation.

The excavation process might take long depending with status of the contaminated soil. It may take long if the soil is highly toxic and requires extra safety precaution. It will also take some time to dig a deep, large or below the water. Time will also be consumed if the soil contains a lot of rocks, debris etc. Excavation is a process that involves various stages including;

Identification of contaminated areas: This involves a thorough research of the site by identifying what could have led to soil contamination and testing the soil for impurities.

Choosing the right instrument for exaction: After the soil has been found to be contaminated, right equipment is used to dig the soil. Depending with the purpose of excavation there are different types of excavators. This equipment are mainly leased as they are costly and purchasing them for a single project might not be cost effective. Therefore, various companies offer these hire business e.g. Eastern Plant Hire. The contaminated or unwanted soil is excavated by standardized excavators such as backhoes and excavators track hoes. It all depends on the location of the site e.g. a site surrounded by buildings will require a smaller excavator. Some sites may have soil contaminated in a deeper situation requiring use of long arm excavators which can dig up to one hundred feet below ground. In some cases, soil might be excavated from below the water table which require pumping of water to facilitate dry excavation.

Soil transportation: When the soil is disposed of, it may be loaded directly into a dump truck to the landfill. It is deposited elsewhere for treatment and covered to prevent soil erosion through water, or by the wind. If excavation is aimed at infrastructural purposes, the soil is used to fill holes and landscaped to prevent erosion.

In conclusion, excavation is a soil engineering technique with more benefits such as cleaning the environment for healthy plants and landscaping to make planet earth beautiful.
