Draft International & European Standard CEN/prEN ISO/DIS 24212 - Remediation techniques applied at contaminated sites has been published for comment. A copy of the standard is available from michael.a.smith@btinternet.com. Comments must be submitted to the Secretary of BSI committee EH4, Joanna Macnamara (Joanna.macnamara@bsigroup.com), by 8 June 2023.
It is a very long document so there is no obligation to review the whole document. A single comment on a single paragraph that interests you can be of value. Any general view as to whether the draft standard should be adopted as a British Standard would be welcome. All comments that are received will be collated and reviewed within EH4 before being submitted to CEN and ISO.
Scope
The document provides guidance on key aspects of remediation techniques and their implementation. It briefly describes principles, the main characteristics and the advantages and limitations to be considered in the selection within an option appraisal of individual or combinations of in situ and on-site remediation techniques, including:
- the type of contaminants to be dealt with;
- current and/or intended site use;
- local legal, policy, socio-economic and environmental contexts.
- It follows the principles for sustainable remediation in ISO 18504.
The scope of this document is restricted to the remediation of contaminated sites, i.e., where soil, or soil gas, ambient air or groundwater are contaminated. It identifies which phase/matrix can be targeted by a technique, e.g., fluid, (groundwater, gas, non-aqueous phase) or solid and which contaminant it can applied to. The document also provides information on hazards that can be associated with the implementation of a remediation.
This document does not provide:
- an exhaustive list of remediation techniques;
- guidance on sites contaminated with radioactive substances, pathogenic or infectious agents, or “pyrotechnic devices (e.g. unexploded ordnances)”;
- guidance on ex situ techniques that are set up off-site;
- a framework that covers all individual situations; or prescribe which technique(s) to use in a specific context.
