The Importance Of Remediation Services For Environmental Sustainability

by | Dec 3, 2020 | Construction

A remediation service of a site is required when one notices any pollutants or contaminants in the soil that can pose unnecessary. Remediation can be defined as the reversing or stopping of environmental damage. When remediation services are commissioned for environmental conservation, pollutants and contaminants are removed from the groundwater, surface water, soil, and sediment. This ensures that these contaminants do not adversely affect human health. To complete the process in the right manner, it is imperative to comply with the regulatory processes, and working with a consultant who is pro in these services is also needed.

Prerequisites of environmental remediation

The following actions need to be decided first before you start the remediation process:

Deciding the consultant: It is very important to find the right consultants, who are experts at remediation services, once the federal government has agreed that remediation is required. The consultant examines the site and analyses the findings to suggest the right remediation technologies. It is the consultants who plan and execute the entire remediation process

Remediation technologies: The consultants then use innovative and modern technology to carry out the remediation process. This helps to save cost, speed up the process, and create an efficient strategy for the remediation service without much guesswork.

Types of remediation strategies

While cleaning up the site, the consultants consider many factors before deciding on the strategy—type of contaminant, mediums like soil, groundwater that have been affected, and the extent of the impact. Once all these factors are analysed, the consultant zeroes down on the potential strategies that can include:

  • Excavation – The removal of contaminants or pollutants from a site
  • In-Situ Injections – Injecting chemical oxidants into groundwater or soil to kill pollutants and contaminants
  • Bioremediation – Making use of microorganisms or specific types of plants to remove or neutralize contaminants
  • Chemical Blending – Includes blending chemicals into the contaminated area to neutralize pollutants
  • Product Recovery – The process involves removing liquid or vaporised contaminant from the medium
  • Pump-and-Treat System – A process of pumping contaminated groundwater out of the ground, treating it to remove contaminants, and then re-inserting it
  • Soil Vapor Extraction – A process of injecting air or steam into the ground and extracting and treating the vapours to purify the soil and groundwater
  • Soil Encapsulation – This process permanently covers contaminated soil to prevent direct contact and leaching of contaminants by rainwater infiltration

Post remediation checklist

Once the remediation service is over, the consultant does a further analysis to find out how much of the risk has been abated. They often offer long-term service with regular follow-ups to evaluate the effectiveness of the technologies and processes used.

The remediation processes can vary in size. While it can be massive spanning over days, some can also be of small scale lasting for just one day. The remediation process is usually conducted in industrial and construction sites to ensure that there are environmental damages that can pose human hazards. Once the remediation is completed successfully it can last for years.
