The legislators (Danish Environmental Protection Agency), the Regulators (the Regional governments) and the performing part (consultants and contractors) in Danish soil and groundwater issues have a very unique working environment based on a strong scientific knowledge on all levels and very competent performers in the field. In 1983 the first Danish legislation on soil and groundwater contamination was implemented. In the last three decades, Denmark have built a unique model for dealing with soil and groundwater contamination. Studies, investigations and remediation of contaminated sites are mainly controlled by the regional authorities and to a lesser extent by private investors who want to develop an area. Civil litigation regarding remediation actions and costs between private landowners are virtually non-existing. The aim of the session is to inspire others by sharing the Danish approach of how to handle contaminated sites on all levels; our good and bad experiences on this topic, and with this, hopefully creating international working relations where we all share, learn and take home the best from each other´s practices.
We propose that the open session will consist of the following presentations and discussions:
• National Legislation of contaminated sites:
The development of the law of contaminated sites in the last 30 years.
• The regional authorities:
The aim of the regional authorities work with contaminated sites.
• KRIPP: Concept for Risk based ranking and prioritization of contaminated sites:
• Site investigation, risk assessment and remediation:
• Brownfield regeneration:
Names of presenters and titles of presentations
• Danish Environmental Protection Agency, Helle Okholm/Ole Kiilerich: Danish legislation of contaminated sites.
The Legislation behind it all and how it has developed over the last 30 years. Why has the law evolved as it has? What are the issues we are trying to solve with the law? What are the challenges we currently face? And how does the Danish legislation comply with EU legislation.
• Danish Regions, Environment and Resource, Christian Andersen: How do the Danish Regions prioritize, investigate and remediate contaminated sites.
The aim of the regional authorities work with contaminated sites.
The overall framework of the regional authority's efforts to regulate contaminated sites.
The regional authorities as a major actor for development of the approach and technology for handling contaminated sites
• COWI, Torben Højbjerg Jørgensen: Investigation and Remediation Methods, developments and state of the art.
The Danish approach to site investigations and risk assessment of contaminated sites.
Working with site conceptual models to secure a high degree of understanding the nature of the pollution and how it is dispersed into the environment.
• Orbicon, Nina Tuxen: KRIPP: Concept for Risk based ranking and prioritization of contaminated sites.
In Denmark more than 30.000 contaminated sites exist and with the yearly budgets the regions have to manage these sites, the task will last for decades. We present a risk based concept for prioritization of the effort including, mass flux calculations, impact in receptors and uncertainty analyses.
• COWI, Ninna Dahl Ravnsbæk: Brownfield Regeneration.
How the Danish approach influences development of contaminated sites as old industrial areas, harbors and old marshalling yards and prevents that regeneration activities causes contamination to spread.
