Environmental remediation

Pollutants in the soil, subsoil and water

Image
The contaminated sites remediation is the set of all those specialized and targeted operations that allow the land and areas recovery compromised by various contamination phenomena, with potential risks for the environment and human being health.

According to the legislation, decontamination is "the set of interventions with the aim to eliminate the pollution sources / polluting substances or reducing this concentration in the soil, subsoil and groundwater to a level below the values ​​classified by the Threshold Concentrations Risk / Contamination "( 240 Article of Legislative Decree 152/2006).

A definition that has a complex link between environmental, economic and various regulatory issues, where it's important to evaluate the situation in its complexity and resolve it thanks to specialized technicians and professionals.

ISOVIT technicians thoroughly analyze the compromised situation area using the most suitable technologies to obtain the best site environmental requalificatione, including an in-depth cost / benefit analysis, especially for the very high critical area.

 

THE DECONTAMINATION PHASES

 
1. Preliminary Investigation Plans draft and execution.

Initial communication to the competent institutions and definition of the characteristics site. Assessment of the distribution and resolution of any contamination.

2. Characterization Plans Design and execution.

Reconstruction of all activities production occurred on the site (places of accumulation and storage of waste and / or raw materials, underground and / or above ground tanks and tanks, dispersing wells, underground utilities networks, etc.) and verification of possible danger centers presence, according to precise sampling and analysis protocols.

3. Land reclamation and safety projects Design and implementation.

Characterization data collected. Preparation of interventions with the aime to remove and contain the spread of contaminants to prevent direct contact with humans (removal of waste, emptying of tanks, collection of hazardous substances, pumping of underground and surface floating liquids, installation of fences and containment works , roofing and temporary waterproofing ...) with monitoring activities. Operational safety, with interventions on contaminated sites, with production activities in operation, mitigating or containment (pumping; drainage trenches; underground ventilation). Environmental remediation and restoration / permanent safety: (contaminated sites not affected by production activities for urban use).

4. Design and construction of hydraulic barrier and pump & treat systems for groundwater.

Decontamination in an emergency safety using an active dam ("hydraulic") with wells or barriers of extraction wells. The Pump and Treat (P&T) where groundwater is withdrawn, purified and discharged into a surface water body for the treatment of polluted groundwater.

5. site-specific environmental risk analyzes development.

It's the risk estimate for human health and the environment relating the potentially contaminated site: analysis of the source of contamination; of the migration paths of pollutants through environmental matrices; the contamination receptors at the site or adjacency.

6. Construction management and technical construction management.

Once the Risk Threshold Concentrations established on the basis of the risk analysis have been approved, the pollution and pollutants sources are eliminated or the concentrations of the same in the soil, subsoil and groundwater are reduced to a equal level to or below the threshold risk concentration values ​​with permanent safety measures. From the authorization to the execution of the works, with the management of relations with the control entities, the preparation of technical specifications.

7. Underground waste removal plans elaboration and execution.

Safety Emergency with removal and containment of the spread of contaminants to prevent direct contact with the population. Removal of waste underground, emptying of tanks and collection of hazardous substances.

8. Plans for the removal of underground tanks elaboration and execution.

The removal of underground cisterns / reservoirs with dismantling and removal of the plant, with building authorization for dismantling. It requires the termination of all direct or complementary activities to the plant.

9. Environmental due diligence.

An area affected by non-highlighted environmental liabilities carries remediation costs that can have significant weight. Isovit helps its customers since the investment assessment phase, employing an expert staff for the design and quantification of the necessary remediation interventions, supporting subsequent real estate and industrial operations. Through documentary studies, inspections, censuses and preliminary investigations, the state of contamination is assessed to estimate the costs of the remediation intervention.
