Remediation techniques applied at contaminated sites (ISO/DIS 24212:2023)

This document provides an overview of principles and characteristics on most commonly used
remediation techniques. In particular, it provides:
— standard terminology, principles, scope, and key aspects on design/dimensioning and monitoring for
each remediation technique, but also an overview of the known advantages/limitations of each
technique;
— informative advice on the remediation option appraisal stage, i.e. how to assess and choose the
most relevant single or combined remediation technique taking into account the type of pollutant as
well as the local legal, policy, socio-economic and environmental context.
The scope of this document is restricted to the remediation of contaminated land — that is
demonstrably breaking the source-pathway-receptor linkages — in a manner that has been shown to
be sustainable on a site-specific basis in a specific legal context.

Sanierungstechniken an kontaminierten Standorten (ISO/DIS 24212:2023)

Dieses Dokument enthält Leitlinien zu den wichtigsten Aspekten von Sanierungstechniken und ihrer Umsetzung. Es beschreibt kurz die Grundsätze, die wichtigsten Merkmale sowie die Vorteile und Grenzen einzelner oder kombinierter In situ- und On site-Sanierungstechniken, die bei der Auswahl und Bewertung der möglichen Optionen zu berücksichtigen sind. Diese beinhalten:
—   die Art der zu behandelnden Verunreinigungen;
—   die derzeitige und/oder beabsichtigte Nutzung des Standorts;
—   lokale rechtliche, politische, sozioökonomische und ökologische Zusammenhänge.
Es folgt den Grundsätzen für eine nachhaltige Sanierung nach ISO 18504.
Der Anwendungsbereich dieses Dokuments beschränkt sich auf die Sanierung von Altlasten, d. h. von kontaminiertem Boden, kontaminierter Boden- oder Umgebungsluft oder kontaminiertem Grundwasser. Es gibt an, auf welche Phase/Matrix eine Technik abzielen kann, z. B. Flüssigkeit (Grundwasser, Gas, nichtwässrige Phase) oder Feststoff, und auf welche Verunreinigungen sie angewendet werden kann. Das Dokument enthält auch Informationen zu Gefährdungen, die mit der Durchführung einer Sanierung verbunden sein können.
Dieses Dokument enthält nicht:
—   eine vollumfängliche Liste der Sanierungstechniken und  verfahren;
—   Leitlinien für Standorte, die mit radioaktiven Substanzen, Krankheitserregern bzw. infektiösen Stoffen oder „pyrotechnischen Gegenständen (z. B. nicht detonierten Kampfmitteln)“ belastet sind;
—   Leitlinien zu Ex situ-Verfahren, die außerhalb des Standorts durchgeführt werden;
—   Rahmenbedingungen, die alle einzelnen Situationen abdecken, oder die vorschreiben, welche Technik(en) in der jeweiligen Situation anzuwenden ist/sind.
