Remediation techniques applied at contaminated sites

This document provides requirements and guidance on key aspects of remediation techniques. It describes the principles, main characteristics, 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. This document is applicable 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 liquid) or solid, and which contaminant it can applied to. This document also provides information on hazards that can be associated with the implementation of 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 prescribes which technique(s) to use in a specific context.

Techniques de dépollution appliquées aux sites pollués

Le présent document fournit des exigences et des recommandations relatives aux principaux aspects des techniques de dépollution. Il décrit les principes, les principales caractéristiques, les avantages et les limites à prendre en compte lors de la sélection, dans le cadre d'un bilan coûts-avantages des techniques de dépollution in situ et sur site, individuelles ou combinées, notamment: — le type de polluants à gérer; — l'usage des sites actuel et/ou prévu; — le contexte local juridique, politique, socio-économique et environnemental. Le présent document est applicable à la dépollution des sites pollués, c'est-à-dire lorsque le sol, les gaz du sol, l'air ambiant ou les eaux souterraines sont pollués. Il identifie la phase/matrice qui peut être ciblée par une technique, par exemple un fluide (eaux souterraines, gaz, liquide de la phase organique non miscible) ou un solide et le polluant auquel cette technique peut s'appliquer. Le présent document fournit également des informations sur les dangers qui peuvent être associés à la mise en œuvre d'une dépollution. Le présent document ne donne pas: — de liste exhaustive de techniques de dépollution; — de recommandation sur les sites pollués par des substances radioactives, des agents pathogènes ou infectieux, ou par des «dispositifs pyrotechniques» (par exemple, des munitions n'ayant pas explosé); — de recommandation sur les techniques ex situ mises en œuvre hors site; — un cadre couvrant toutes les situations individuelles ou prescrivant la ou les techniques à utiliser dans un contexte spécifique.

Overview

ISO 24212:2024 - Remediation techniques applied at contaminated sites provides requirements and guidance for selecting and implementing in situ and on-site remediation techniques. The standard covers principles, main characteristics, advantages and limitations of remediation options for contaminated soil, soil gas, ambient air and groundwater, and identifies which phase or matrix (fluid or solid; e.g. groundwater, gas, NAPL) and which contaminants each technique can target. It also addresses hazards and risk management during remediation and good practice for strategy appraisal, testing and monitoring.

Key technical topics and requirements

  • Remediation strategy appraisal: Good-practice steps for identifying feasible strategies, evaluating options and selecting a final remediation strategy based on site objectives and constraints.
  • Selection criteria: Consideration of contaminant type, current/intended site use, and local legal, policy, socio‑economic and environmental contexts.
  • Technique descriptions: Structured summaries of common approaches (examples included in the standard):
    • In situ chemical oxidation (ISCO)
    • In situ chemical reduction (ISCR)
    • Enhanced in situ bioremediation (EISB)
    • Monitored natural attenuation (MNA)
    • Incineration
    • In situ thermal remediation (ISTR)
      Each technique entry covers principle, scope/applicability, technology description, design considerations, key monitoring parameters, advantages/limitations, EHS aspects and compatible combinations.
  • Hazard and risk management: Identification and controls for hazards related to contaminated media, asbestos, dust, odours, contaminated waste, equipment, unexpected finds (including UXO), ground stability, confined spaces, chemicals, manual tasks, noise and long‑term monitoring.
  • Testing and validation: Emphasis on laboratory testing and pilot tests to verify effectiveness and refine design before full-scale implementation.
  • Limitations and exclusions: Not exhaustive; excludes guidance for radioactive, pathogenic/infectious agents, and pyrotechnic devices (e.g. unexploded ordnance) remediation; and does not cover off‑site (ex situ) techniques established off-site.

Practical applications

ISO 24212 is designed to support:

  • Option appraisal and technique selection during site investigation and remediation planning
  • Design consideration and monitoring program development for on-site and in situ remediation projects
  • EHS planning and risk assessment during remediation implementation Use cases include brownfield redevelopment, groundwater clean‑ups, industrial site remediation and long‑term management of contaminated land.

Who should use this standard

  • Environmental consultants and remediation engineers
  • Site owners and developers
  • Regulatory agencies and permitting authorities
  • Environmental health & safety (EHS) professionals
  • Project managers overseeing contaminated site remediation

Related standards

ISO 24212 complements national guidance and other ISO standards on environmental management, site investigation and contaminated-land frameworks. It should be used alongside local regulatory requirements and technical guidance for detailed design, permitting and health‑and‑safety compliance.
