Risk assessment Various questions might be raised in connection with the identification of a contaminated site, such as whether there is a risk for people who will be using the site or for the groundwater quality or any nearby surface water resources. To clarify such issues, Orbicon carries out risk assessments that allow both property owners and environmental authorities to decide on how the contamination is to be handled.
We evaluate the impact of soil contamination on: -
Underlying groundwater -
The indoor climate of buildings on the site -
The impact on humans in terms of breathing or ingesting soil particles -
The impact on the nature, i.e. flora and fauna, of the site -
Building materials Risk assessment at the property level The simplest form of risk assessment at the site level is in Denmark based on the Danish Environmental Protection Agency’s guidelines for cleanup of contaminated sites.
For this, we use the accompanying spreadsheet, JAGG. The spreadsheet includes parameters describing the physical and chemical properties of contaminants as well as parameters describing the geology and transport properties of the soil on the site.
As a basis, we use JAGG’s standard values for various types of soil. If a more precise evaluation is necessary, we can use data from the specific site to the extent that a technical inspection of the site has taken place. An example of this could be the ability of the soil to transport water, or other conditions. |
