3 Contaminated Soil Remediation Strategies

The manufacturing processes used to create commercial goods can sometimes be harmful to the environment. In order to ensure that the environment is returned to its pre-existing, non-contaminated condition, companies must engage in remedial activities.

Here are three types of remediation strategies that your own company can use when dealing with contaminated soil in the future.

1. Traditional Excavation

One of the easiest ways to restore a contaminated area to pristine condition is to remove any soil that has been exposed to polluting contaminants. This can be done through traditional excavation. To complete this type of remediation, you will need access to an excavator and several dump trucks.

Once the contaminated dirt is removed from the site it will need to be deposited in a regulated landfill. These landfills are designed specifically to house contaminated soils, and many regulated landfills work to remove contaminants from the soil over time. Although traditional excavation may be a simple way to get rid of contaminated soil, moving your soil off site can cost $1,200 per truckload.

2. Bioventing

When your soil has been contaminated by volatile organic compounds (VOCs), which are a group of carbon-containing compounds that evaporate at room temperature, you may want to consider investing in bioventing as a remediation strategy.

Bioventing is a form of soil aeration. Concentrated injections introduce oxygen into the soil during bioventing. When the VOCs come into contact with the oxygen, they begin to degrade. Eventually, VOCs will completely disappear from your soil. Bioventing has been approved for use as a soil remediation strategy in 38 states, and can also be used in all 10 Environmental Protection Agency regions.

3. Bioaugmentation

Introducing selected biological organisms into your soil can help you target the specific contaminants that have found their way into the environment surrounding your manufacturing facility. The process of introducing biological organisms into the soil is commonly referred to as bioaugmentation.

Though commonly used to treat contaminated wastewater stores, as a soil remediation strategy, bioaugmentation can be very effective. If your soil samples test positive for compounds like phenols, chlorinated aromatics, or aromatic hydrocarbons, then investing in bioaugmentation could be an easy way for you to manage these contaminants in the future.

Contaminated soils present a real problem for the environment surrounding your manufacturing facility. Be sure that you consider excavating, bioventing, or bioaugmentation as remediation strategies to clear contaminants from your soil in the future. Contact a company like A. G.
