Remediation of contaminated sites

Remediation service for contaminated sites

We specialize in the remediation of contaminated sites. Thanks to our experience at the national level, we offer technical and operational support in the implementation of the different phases governed by Title V Part four of Legislative Decree 152/06 and subsequent amendments.

During the process of remediating contaminated sites:

  • we ensure full compliance with current regulations;
  • guarantee the safety of the people involved;
  • preserve the environment.

Operational and administrative procedures of the remediation process

We support the client throughout the entire procedural process required by the legislation relating to the remediation of contaminated sites. The phases of the remediation process are subject to approval within the framework of specific Service Conferences involving the relevant public authorities.

The remediation process provided for in art. 242 of Legislative Decree 152/06 and subsequent amendments and additions, takes place according to the following main phases:

1. Communication to the Competent Authorities about the polluted site

The person in charge of the contamination, within 24 hours from the occurrence of a potentially contaminating event or the identification of a historic contamination, immediately notifies the Competent Authorities. He is also required to implement the necessary prevention and emergency safety measures to contain the effects of the contamination in the environmental matrices of soil, subsoil, and groundwater.

2. Implementation of preliminary investigation

Carrying out a preliminary investigation related to the parameters subject to pollution in order to verify compliance with the Threshold Contamination Concentrations (TCC).

3. Presentation of the Characterization Plan

In case the exceeding of the CSC is ascertained, it is necessary to communicate it to the competent authorities and to provide for the presentation of the Characterization Plan. This document is aimed at planning the necessary investigations to identify the areas and volumes of soil affected by contamination, as well as any contamination of groundwater.

4. Preparation of the Risk Analysis

Based on the characterization data, a specific Site Risk Analysis is prepared to determine the Risk Threshold Concentrations (CSR) for each contaminant that has exceeded the CSC.

In case the concentrations detected on the site are lower than those determined by the Risk Analysis, the site is not contaminated. A site is contaminated when the values of the risk threshold concentrations (CSR) are exceeded.

5. Presentation of the Operational Remediation Project

If the site is found to be contaminated, it is necessary to submit an Operational Remediation or operational or permanent safety project in order to bring the risk resulting from the current contamination of the site to an acceptable level.


We are registered in the Environmental Managers Register in Category 9 - remediation of contaminated sites for the implementation of remediation projects or for securing purposes.

Some of our interventions

In our construction sites, the use of aggregates from the Pradamano recovery plant is frequent (for example for embankments and road sub-bases, backfills, restorations) or from the Monfalcone recovery plant (silt and sand for use in non-structured works).

In our remediation works of contaminated sites, we apply sustainability principles not only in the processes, but we also include them in the methodological choices and in the new characterization technologies (in the geological/hydrogeological, chemical and biological sphere), without forgetting the importance of information visualization and management tools to support decision-making strategies.

The remediation activity contributes to the ecological transition: it reduces the risks associated with environmental contamination, and restores compromised ecosystems to a healthy and sustainable state.
