Impact/Purpose:
The objective of this work was to develop and describe a systematic framework for optimizing the evaluation of data at contaminated sites. It is restricted to characterization of the contamination source in soil and is focused to account explicitly for uncertainties and to optimize statistical methods.
Description:
The Swedish guidelines for the evaluation of data for the purpose of a risk assessment at contaminated sites are of a qualitative character, as opposed to the USEPA’s Data Quality Objective Process. In Sweden, this can sometimes be a problem because the demands on data quality are unclear and often guided by the experience of the consultant or by the persons at the regulatory agency, rather than by national guidelines. A framework for evaluating data from contaminated sites is thus useful, both for consultants and for the regulatory agencies. Such a framework can facilitate not only a common ground for demands on data evaluation, but also a transparent and scientific basis for data evaluation where statistical methods and uncertainty analysis are in focus.
