From contaminated soil to solution: Everything you need to know about Environmental Remediation Systems

In practice

In a landfill that received more than 320,000 tons of industrial waste between 1974 and 1987the challenge was to treat an effluent with a highly variable compositionAs a direct result of the diversity and complexity of the waste disposed of over the years, EP stepped in with a treatability study conducted by the PDI team, developing the best technical solution for the case. Since 2010, we have complete operation of the WWTPwith an average flow rate of 10 m³/h, guaranteeing:

• Stability of treatment even in complex scenarios;
• Compliance with environmental parameters;
• Support for site remediation actions.

Today, this project is an example of how science and engineering can transform an environmental liability into a sustainable and safe operation.

How the environmental remediation system works

Remediation systems can work in two ways:

• Mitigation: creating barriers or temporary solutions to prevent contaminants from reaching sensitive areas.

• Removal/Treatment: Actions that seek to eliminate or degrade the contaminants present in the soil and/or groundwater.

This is a technical process that requires detailed assessment of the site, identification of compounds, technical and economic feasibility analysis, selection of the best technology and ongoing monitoring. Therefore, there is no generic solution – each case requires a tailor-made project.

Where is remediation applied?

Remediation techniques are particularly suitable for:

• Chemical and petrochemical industries;

• Areas contaminated by gas stations;

• Oil and gas sectors;

• Mining;

• Disused industrial areas;

• Environmental licensing projects or redevelopment of urban areas.

The complexity of remediation projects

Implementing an effective remediation system goes far beyond installing equipment. It requires a multidisciplinary approach, taking into account:

• • The origin and extent of contamination;
  • The type of soil and hydrogeological characteristics;
  • The critical parameters to be monitored;
  • Choosing the right inputs and technologies;
• The operation and maintenance plan.

All this under constant pressure for fast, efficient and environmentally responsible deliveries.
