Soil Protection and Contaminated Sites Rehabilitation - Technical Documents


Reports and inventory

Reports

The MELCC makes reports, including general and/or specific statistics on the management of sites that have been contaminated by anthropic activity, available to the public. Data in the reports comes from the Système de gestion des terrains contaminés (GTC), the Répertoire des dépôts de sols et de résidus industriels (DSRI) and various other ministerial information systems. In general, the inventoried sites are selected on the basis of contaminant levels found during characterization that exceed the values listed in Schedule I of the Land Protection and Rehabilitation Regulation (or criterion B of the Guide d’intervention – Protection des sols et de réhabilitation des terrains contaminés).

The reports shed light on a variety of facts and issues that can affect the land. However, whenever the data shown is partial in nature, care must be taken in interpretation.

Inventory evolution of Gerled industrial residue landfills from 1983 to 1998

Guides and Guidelines

General

Soil and underground water characterization

Notice to readers
The current PDF document is a facsimile of the 2003 Guide de caractérisation des terrains produced by the Ministère de l’Environnement (former name of the MELCC) and published by Les Publications du Québec. The original publication is out-of-print and is now available only in facsimile form online.

The guide sets out the objectives and elements that need to be taken into account in land characterization studies, particularly in regard to soil quality assessment and impacts on underground and surface water.

Readers will find therein the notions needed for conducting a characterization study, as well as a description of procedures and planning methods for such studies.

The guide is meant to be used by various land stakeholders, such as project proponent experts, consultants, industry representatives, owners, municipalities and financial institutions.

These guides describe planning and sampling best practices aimed at ensuring quality control and the validity of derivative scientific information.
