This morning, April 10, S-Risk version 1.2.2 will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 12 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.

We have updated the following FAQ entry:

• Why do mercury, copper, nickel, zinc and lead simulations sometimes give counterintuitive results?

The Technical Guidance Document of the S-Risk model and its Annex have been updated. You can find the new versions on our Documents page.

Ordering S-Risk accounts applicable to the Walloon region is now possible. More information about prices and how to order them can be found on our Registration page. Walloon accounts will be created and activated as soon as the official starting date of S-Risk in Wallonia is known.

The S-Risk user manual has been updated to reflect the latest changes introduced with S-Risk 1.2.1. You can find English and Dutch versions on our Documents page.

This morning, S-Risk has been updated to version 1.2.1. This release introduces a new, much-requested archiving feature, and a range of backend changes to enable the use of S-Risk in the Walloon region. A considerable number of generic S-Risk issues were fixed and improved as well.
More details can be found on our Release notes page.

The Technical Guidance Document of the S-Risk model and its Annex have been updated. You can find the new versions on our Documents page.

As from December 12, 2016, the S-Risk licence and invoice system will be automated more. Therefore, the user agreement had to be revised and updated. The new version of this agreement can be found on our Registration page. Additional information will follow soon.

We have added two more FAQ entries, based on the feedback we have received via the S-Risk helpdesk:

• Why does my simulation take so long to calculate?
• How to choose the appropriate soil type?

We have added more FAQ entries and updated existing ones, based on the feedback we have received via the S-Risk helpdesk.

FAQ entries updated:

• Why does S-Risk give a warning message for a calculated critical concentration in application I or III? (replaces “Why does S-Risk sometimes fail to find critical soil concentrations?”)
• What are the browser or network requirements for running S-Risk?
• How to simulate the presence of a paved surface?
• Why can’t I customize the properties for copper, nickel, mercury, zinc or lead?

New FAQ entries:

• Why do RI (or ExCR) and CI results differ for volatile substances?
• How to deal with a contamination that is only partially situated below a building?
• Why do mercury, copper, nickel and lead simulations sometimes give counterintuitive results?
