CEN/TC 444/WG 8 - Assessment

This document provides guidance on developing and using conceptual site models (CSMs) through the various phases of investigation, remediation (if required), and any subsequent construction or engineering works.
It describes what CSMs are, what they are used for and what their constituents are. It stresses the need for an iterative and dynamic approach to CSM development.
This document is intended to be used by all those involved in developing CSMs and by those who rely on using them such as regulators, landowners, developers, and the public (and other relevant parties). Ideally, this includes representatives from all phases of the investigative and remedial processes, for example, preliminary assessment, detailed investigation, baseline human health and environmental risk assessments, and feasibility study, and, any subsequent construction or engineering work.
NOTE 1    This document is applicable whenever the presence of "potentially harmful" or "hazardous" substances are present irrespective of whether they are naturally occurring or present due to human activity (i.e. are "contaminants").
NOTE 2    Although most of the principles described for developing CSMs in this document can apply to other domains, such as groundwater resources management, the present document is specifically written for the management of potentially contaminated sites or known contaminated sites.

This document gives general guidance on the selection of procedures for the establishment and maintenance of programmes for long-term monitoring of soil quality. It takes into account the large number of objectives for soil-monitoring programmes.
This document is intended to help provide a basis for dialogue between parties which might be involved in a monitoring scheme.

This document provides guidance on the principles behind, and main methods for, the evaluation of sites, soils and soil materials in relation to their role as a source of contamination of groundwater and their function in retaining, releasing and transforming contaminants. It is focused on contaminated land management identifying and listing relevant monitoring strategies, methods for sampling, soil processes and analytical methods.

This document gives guidelines for the principles and main methods for the determination of background values for inorganic and organic substances in soils at a local/regional scale. The site scale is excluded.
It gives guidelines for sampling and data processing strategies. It identifies methods for sampling and analysis.
This document does not apply to the determination of background values for groundwater and sediments.

ISO 11504:2017 gives guidelines with regard to the choice of fractions and individual compounds when carrying out analysis for petroleum hydrocarbons in soils, soil materials and related materials, including sediments, for the purpose of assessing risks to human health, the environment and other possible receptors. Since many products based on petroleum hydrocarbons often contain substances that are not hydrocarbons, the recommendations also encompass such compounds where relevant.
ISO 11504:2017 also includes relevant background information on which the recommendations are based together with guidance on the use of the fractions recommended in the assessment of risk.
ISO 11504:2017 does not set criteria or guidelines for use as assessment criteria, since this is typically a national or regional regulatory issue. This document also does not include recommendations as to the specific model for the exposure assessment or the specific parameter values to be used; with respect to guidance on this matter, reference is made to ISO 15800.

This European Standard specifies requirements for a waste testing programme regarding mainly objectives, planning and report with the intent to ensure reliable and comparable results when using the reference methods that have been developed and/or adopted by CEN/TC 292.
The planning and report aspects of this European Standard are applicable to any waste testing programme dedicated to the determination of one or several parameters. They are also applicable to all testing steps for each parameter from sampling up to reporting whether these steps are taking place in the field (e.g. sampling) or in the laboratory (e.g. analysis-quantification).
This European Standard does not address aspects of safety for activities in the field and inside laboratory.
NOTE   The term planning a testing programme is used here with the general meaning of organizing a testing programme and being in accordance with the terms testing plan, sampling plan, laboratory plan used in the present European Standard.

ISO 17402:2008 provides guidance for the selection and application of methods to assess bioavailability for the characterisation of contaminated soil and soil materials. ISO 17402:2008 does not give a selection of the best applicable methods, but specifies boundary conditions and principles of methods to be used and gives the minimal requirements for the development of methods. The results obtained from such methods can be used as an estimate of bioavailability in a risk-assessment approach.
The contaminants considered in ISO 17402:2008 are metals, including metalloids, and organic contaminants, including organometal compounds. This International Standard is also applicable to metals originating from natural geological and pedological processes (natural pedo-geochemical content).
ISO 17402:2008 can also be applied to sediments.
