Environmental remediation is the removal of harmful waste from the environment. This includes the elimination of waste products from the soil, the protection of groundwater, and the removal of pollutants from surface water. For successful environmental remediation, you should have a remediation plan. A remediation plan will help in getting rid of pollutions from the environment. A remediation plan will also help to achieve the following:
1. Soil remediation
Soil remediation is the removal of pollutants from the soil. This practice helps in protecting the biota; a polluted environment is harmful to all living organisms.
Soil remediation will also help prevent soil degradation. There are different techniques used in soil remediation. Here are some of them:
Thermal desorption method
Soil vapor extraction method
Solidification and stabilization method
2. Groundwater remediation
Groundwater is water held within rock crevices below the earth’s surface. Therefore, groundwater remediation is the process used in removing pollutants from or preventing the contamination of underground water. Examples of groundwater are; aquifer water and well water. Groundwater can be used for drinking, industrial processes and irrigation since the water is usually clean.
Groundwater can get contaminated by chemicals. For instance, excessive use of fertilizers and pesticides or spills from industries may seep into the ground and contaminate the groundwater. Polluted groundwater is a threat to the community health because it may cause a number of diseases. For you to avoid these harmful effects of contaminated groundwater you may consider applying these techniques to remove the contaminants:
Pump and treat method
Use of dual-phase vacuum extraction method
Chemical precipitation method
Carbon absorption method
Membrane separation methods among others
3. Sediment remediation
Sediments are natural organic or inorganic material found at the bottom of water bodies. Sediment remediation is the process in which sediments are treated from harmful contaminants. Examples of sediments are; silt, clay, sand, and decaying matter. Contamination of sediments is mainly caused by oil spills, agricultural runoffs, industrial spills, and pesticides.
4. Surface water remediation
Surface water is the water found above the ground. Surface water remediation simply means treatment and removal of contaminants from water found on the ground. Examples are lakes, rivers, catchment water, storm run-off, and oceans. Surface water should be treated to avoid diseases like malaria and bilharzia because when the water is polluted the area becomes a breeding site for mosquitoes and snails leading to the diseases.
Importance of environmental remediation
Helps reduce the risks of people getting sick from drinking contaminated water
Plants that grow on contaminated soil can also cause health problems
Important living organisms in the soil may die due to ground contamination
In the age of rampant ground, water, and air pollution, environmental remediation is a holy grail for Mother Nature. Every effort towards environmental remediation is important.
