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.

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.

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?

Coming Tuesday, September 13, additional measures will be implemented on the S-Risk platform, intended to resolve the recent communication problems between the web browser and the server system of S-Risk. For this reason, the S-Risk web application will be temporarily unavailable between 12 am and 1 pm. The implemented solution will be evaluated by us after two weeks. Feedback from you on S-Risk performance and response times during this period is highly appreciated!

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 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?

We are currently preparing a solution to fix the communication issues between the web browser and our server system. Therefore, we sometimes need to make use of the production server system. This may lead to temporary slow responses of S-Risk in your web browser, appearing like the system is not responding or hanging. In most cases, S-Risk will work again after refreshing your browser page (using the Refresh button on your browser or the F5 key). We thank you for your patience while we work out a solution.

We will organise a next S-Risk training session on October 13, 2016. For more information on the training programme or how to register, see our Events page.

The S-Risk user manual has been updated to reflect the latest changes introduced with S-Risk 1.1.5. You can find English and Dutch versions on our Documents page.

At the moment, we experience communication issues between the web browser and our server system. This may lead to timeouts in your web browser, appearing like the system is not responding or hanging. In most cases, S-Risk will work again after refreshing your browser page (using the Refresh button on your browser or the F5 key). Thank you for your patience while we search for a solution.

This morning, S-Risk has been updated to version 1.1.5. This release introduces a major overhaul of the calculation backend for applications I and III and a number of fixes and improvements in reports and user interface.
