In Italy the necessity to restore situations of severe environmental damage is regulated by D.Lgs 152/2006 and subsequent modifications and additions. Besides covering the remediation and environmental restoration of contaminated sites, it defines procedures, criteria and methods to carry out the essential operations to eliminate or at least reduce the concentration of pollutants.

The current legislative framework also defines reference standards regarding the development of activities aimed at detecting, within a specific site, evidence of soil, subsoil and groundwater contamination.

In case of events able to severely harm the site, pollutant concentration is measured to determine whether or not the Contamination Threshold Concentrations (CTCs) are exceeded in the environmental matrices.

In a first stage it is important to distinguish between:

• Potentially contaminated sites;

• Effectively contaminated sites.

Through sampling and analytical tests conducted on soil and/or groundwater samples the site qualifies as a potentially contaminated when CTCs are overtaken.

Thanks to the environmental characterization performed on the potentially contaminated area (which includes all the investigations to be carried out, from sampling of various environmental matrices up to analytical inspections and elaboration models) the conceivable pollution situation of soil and groundwater is ensured thus determining its source and evaluating the resulting health and environmental risk.

If the concentration of pollutants turns out to be higher than the Risk Threshold Concentration (RTCs) established on the basis of characterization plan results and risk analysis procedure the site is classified as contaminated.

Once the contaminants and their sources, migration routes and possible targets have been identified, the conventional solutions are:

• Development of Remediation Plans ( defined as the set of interventions aimed at eliminating pollutants and contamination sources or at reducing their concentration to levels lower than the limits specified by law);

• Operational Safety Commissioning for actual areas ( defined as a set of actions taken in order to ensure an adequate level of safety for the environment and for the people, pending further measures like Permanent Safety Commissioning or Remediation to be realized when the site activities are completed);

• Permanent Safety Commissioning regarding sites where production activity has ceased and Remediation is technically and/or economically unfeasible.

VDP provides environmental consulting services to define the levels of contamination and the possible measures to take in order to assure site safety commissioning and guarantees assistance to public and private institutions in all the technical and administrative procedures.
