General questionnaires on Contaminated Land Management

 Synthesis of answers to questionnaires from other Organizations

Feedback about the use of geostatistics for characterizing contaminated sites

RECORD is a cooperative research network on waste and environment composed of industrial and institutional members. In 2011-2012, the network has launched a study for “a critical feedback on the use of geostatistics for site characterization, polluted either with chemical or radioactive substances”. A survey was conducted in this framework in France and abroad among consulting offices, polluted sites owners and public environmental agencies. The purpose of this survey was to collect stakeholders feeling about the practical use of geostatistics at the different steps of site management (investigation, risk assessment, site remediation, evaluation of remediation performance). The english light version of the survey was diffused to the NICOLE and the COMMON FORUM members.
Participants: Belgium, Brasil, Canada, France, Ireland, Switzerland.
The answers to the survey are compiled into a RECORD-11-0514/1A report (in French) that can be downloaded from www.record-net.org.
Available since July 2014.


European Gasworks Survey

The Production of Gas from Coal and the Manufacture of By-Products
From Extraction to Distribution

(En, Fr and Sp version via academia.edu)

Gasworks were used for the commercial manufacture of gas from coal and oil within Europe from 1806 until the 1980’s. The gas industry extended from Great Britain to Russia and from Norway to Malta. The development of the gas industry in each country was very different and in each case a legacy of polluted land has remained. Information on the manufacture of gas is provided in:

"The Manufactured Gas Industry in Europe"
Slideshow prepared by Dr. Russel Thomas
Parsons Brinckerhoff, Bristol, UK. available from

Although this describes the situation in Great Britain, the technology used was similar across Europe.

This short survey has been prepared by Dr. Russell Thomas to assist in preparing a presentation and paper on the history of the manufactured gas industry in Europe and the environmental legacy which still remains. Detailed answers can be downloaded below:

Evaluation of groundwater screening values for volatile contaminants among different countries

Synthesis of the questionnaire - 2012
(PDF file - 482 KB)
This synthesis is part 1 of a Msc thesis untitled "The use of vapour intrusion models to evaluate groundwater screening values for volatile contaminants" carried out by U. Syikilili for Wageningen University, Netherlands.
Participants: Australia, Austria, Belgium Flanders, Belgium Walloon, Czech Republic, Denmark, Finland, Germany, Ireland, Italy, Lithuania, the Netherlands, New Zealand, Poland, Spain, and the United States of America.

The questionnaire involved several questions about the purpose for developing groundwater screening values, protected targets, protection levels, exposure pathways and derivation methods (particularly, models, assumptions, scenarios) that are used to derive the groundwater screening values.

Ten volatile contaminants that are commonly detected in groundwater in most of the
participating countries are selected, so as to be used to identify the difference in groundwater screening values. These contaminants include: benzene, ethylbenzene, toluene, naphthalene, vinyl chloride, trichloroethene, tetrachloroethene, trichlorobenzene, tetrachlorobenzene, and Methyl tert-Butyl Ether (MTBE).


Monitoring data on pentachlorophenol (PCP) and pentachloroanisole (PCA) in contaminated sites

Compilation of answers - 2012
(PDF file - 352 KB)
The investigation was carried out by the Austrian Environmental Agency.
Participants: Belgium (Wallonia and Flanders), Finland, Netherlands, Poland and Spain (Basque Country).

The Austrian Environmental Agency forwarded to the chair Darmendrail Dominique on May 10th the following request:

At EAA a study on PCP is under way. A particular question is whether PCA is of relevance as a metabolite of PCP. As PCP is not a pollutant of major concern at contaminated sites in Austria, we don’t have any monitoring data. Therefore we would appreciate responses regarding the following questions:

  • Have you been facing PCP-contamination of soil or (ground-)water which has been caused by a contaminated site?
  • If yes, did monitoring data show evidence for PCA occurring as a metabolite of PCP?
  • If yes, are there any scientific or technical reports available?
  • Are you aware of any database including monitoring data on PCP and PCA?

The chair kindly distributed the request on 14th of May 2012 to the CF-members. By the end of May 7 members delivered an answer to the questions stated above.


Weed control on site

Compilation of answers - 2012
(PDF file - 312 KB)
The investigation was carried out by r3 Environmental Technology Ltd, United-Kingdom.
Participants: Austria, Belgium, Estonia, France, Ireland, Spain, Switzerland, United-Kingdom.

The original aim of the questions was to help with an EU proposal on the control of invasive plants on brownfield and urban land.  However, it does appear that ‘biological’ contamination of brownfield and urban land is relatively widespread as a problem.  The survey responses may therefore be of general interest to any stakeholders involved in contaminated land management.  r3 has compiled additional information via technical / grey literature review which is available on request to r3.


Major issues related to remediation of mining sites

Compilation of answers via the ICCL web site - 2011
The investigation was carried out by ICCL
(International Committee on Contaminated Land
Participants: Argentina, Autralia, Austria, Belgium, Canada, England, Europe, Finland, France, Germany, Hungary, Israel, Serbia, South-Africa, Sweden, United-States of America.


Handling of contaminated soil

Report of answers - 2011
(PDF file - 891 KB)
The investigation was carried out by the Technical and Environmental Administration, City of Copenhagen, Denmark.
Participants: Amsterdam, Copenhagen, Hamburg, Helsinki, London, Oslo, Stockholm, Vienna.

The Technical and Environmental Administration, City of Copenhagen is conducting a project to increase their knowledge regarding handling of contaminated soil. As a part of the project, in January and February 2011, a questionnaire was sent of to a number of Capital Cities in Europe. The questionnaire pertains to the handling, treatment and final disposal, as well as to threshold values for contaminated soil. The following report is based on the responses to the questionnaire. It reports all the answers from the participating cities (in alphabetical order) and it gives a brief summary of the answers to each question. It has been distributed to the participants, which allows for all the participating cities to derive benefit from the project.
