The WHO European Centre for Environment and Health plans to develop a set of best practices on urban redevelopment of formerly contaminated site, for a wide audience, including urban planners and policymakers, stakeholders and researchers. To this end, we are collecting case studies on the environmental and health impacts of urban redevelopment of contaminated sites.

We are looking for case studies that match the following criteria:
A formerly contaminated site was redeveloped or converted to enable a new urban purpose on or next to it;
  • Former use before conversion included agricultural, industrial, commercial, storage, waste disposal, military or transport-related functions, or the area was contaminated due to an industrial accident or similar somewhere else;
  • New use of the site after remediation (e.g. removal of contaminants, soil cleaning, establishing physical barriers) includes any urban functions with public access, such as residential areas, recreational sites, commercial or retail areas (e.g. supermarkets or business parks), public services, parks and green spaces, or mixed uses;
  • The redevelopment project was carried out in the WHO European Region (country list at;
  • The remediation and redevelopment of the contaminated site was finalized before 2018 (so that reliable information on the impacts can be compiled);
  • Data are available on environmental impacts and/or health effects that are associated with the former contamination, and/or the remediation and redevelopment process.
If you feel that a project you were involved in meets the above criteria for a case study, please fill in the details in this template. Case studies can be submitted from local authorities, civil society and non-governmental organisations, research groups, urban planners and professionals involved in remediation of contaminated sites, or other stakeholders that have implemented or worked on the rehabilitation of contaminated areas.

Please do not hesitate to submit a project with unexpected or even possibly negative outcomes, as this can provide valuable and useful information for future initiatives, and may inform on how environmental impacts and health effects of former contaminated sites can be monitored successfully.

Please note that this case study collection aims to establish a general overview about the use and redevelopments of formerly contaminated sites in the WHO European Region. The case studies will contribute to a WHO report on environmental challenges and health impacts of redeveloping formerly contaminated sites, which will be publicly available.

Filling out the case study template takes approximately 45-60 minutes. Case study contributors will be acknowledged with their names and affiliations in the case study working paper, published as part of the forthcoming WHO report.

Finally, if you wish for your entry to be anonymous ("case study from country X"), you can indicate this in the questionnaire. Neither the name of the project nor the site and its exact geographic location will be published.
