Capping

Installation of an impermeable cover over landfill sites and/or polluted areas.

Characterisation

Detailed chemical/physical analysis of potentially polluted areas.

CTC

Contamination Threshold Concentrations, levels of environmental matrix pollution above which site characterisation and site-specific risk analysis are required.

Decommissioning

The act of closing, reclaiming and demolishing industrial plants.

Draining trench

Excavations which enable the capture or disposal of water from/into surrounding soil, filled with natural and highly permeable inert materials (gravel or quarry debris).

Draining trench

Excavations which enable the capture or disposal of water from/into surrounding soil, filled with natural and highly permeable inert materials (gravel or quarry debris).

Emergency Safety Containment Barrier

A hydraulic barrier (system of wells for the pumping of groundwater), or a physical barrier (sheet piling, impermeable area, etc.), installed for the emergency safety containment of the polluted Site or Area

ORP

Operative Reclamation Project.

On site technology

Reclamation systems consisting of equipment dislocated throughout the site and which treats soil/water, without requiring removal from natural location.

Off site technology

A reclamation method involving the removal/extraction of the environmental matrix and its treatment in plants beyond the site

On site technology

A reclamation method involving the removal/extraction of the environmental matrix and its treatment directly at the site

Pumping

Aspiration and extraction of groundwater.

Photovoltaic

A plant which generates electric power from solar energy.

Permanent safety containment

Containment works at a site designed and implemented as a definitive reclamation operation.

Percolated substances

Liquid normally caused by the infiltration of water into a mass of waste or by the decomposition of waste.

Phytoremediation

Reclamation technique involving the use of plants for the treatment of contaminated environmental matrices.

Piezometer

An instrument which is placed vertically into the ground using a probe to measure water pressure in an aquifer.

Pump & treat

Combined system for groundwater extraction and treatment.

Risk Analysis

Health risk analysis enables the quantitative assessment of risks to human health connected to the presence of pollutants in environmental matrices, and the definition of reclamation objectives.

RTC

Risk Threshold Concentrations, levels of environmental matrix pollution above which site characterisation and site-specific risk analysis are required, as specified in Annex 5 to the fourth part of this decree.If the potentially contaminated site is located in an area affected by anthropic or natural phenomena which exceed one or more contamination threshold concentrations, said concentrations are taken to be equal to existing background values for all exceeded values.

- Risk Threshold Concentrations (RTC): the contamination levels of environmental matrices, established on a case-by-case basis, with the application of a site-specific risk analysis procedure in accordance with principles illustrated in Annex 1 to the fourth part of this decree and on the basis of characterisation plan results; if exceeded, safety containment and reclamation are required.Concentration levels defined in this manner constitute acceptability levels for the site.

Revamping

Operation involving the review and restructuring of industrial plants with the purpose of increasing the useful life of facilities in the production process.

Sheet piling

Sheets, normally made from metal, which are driven into the ground at various depths to create separation or support barriers in the event of selective excavation operations.

SIN

Site of National Interest.

Topsoil removal

Removal of topsoil.

TAF

Groundwater treatment
