Helpdesk availability over the holidays

The S-Risk helpdesk will not be available over the Christmas holidays (starting December 26, 2016). Please keep sending your questions over, they will be answered as soon as possible from January 9, 2017 onwards.

User manual updated

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.

S-Risk updated to version 1.2.1

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.

S-Risk 1.2.1

This release is the first public release in the 1.2 series. It introduces a new, much-requested archiving feature, and a range of backend changes to enable the use of S-Risk in the Walloon region. During this process, a considerable number of generic S-Risk issues were fixed and improved, too.

New features

  • added "Archiving" functionality for the simulation overview: simulations not consulted during the last two years, will be archived automatically; other unneeded simulations can be moved manually out of the way

Introduction of S-Risk Wallonia

  • parameter database is extended to cover Walloon-specific studies - available in Walloon S-Risk accounts. This includes additional chemicals, soil layers, land uses and fine-tuning of default parameter values to the Walloon legislative and environmental context.
  • extended account functionality to cover Walloon accounts next to Flanders/Brussels accounts
  • interface adjustments to indicate the S-Risk region associated with the logged in account
  • introduced read-only accounts for transitioning customers
  • revised of the licensing agreement and registration system to cope with the new cross-regional context

General fixes & changes

  • further structural changes to the database to improve performance and responsiveness 
  • backend improvements for database consistency and robustness of parameter defaults
  • fine-tuning of the optimization algorithm to ensure results in a wider range of concentrations
  • fine-tuning of the comment requirements when changing parameters
  • minor corrections and adjustments in parameter database:
    • "total time on site" parameter corrected for some scenarios - without influence on the results
    • default value for ABS_dermal for blank chemicals is changed to 0.25
    • corrected the CAS numbers for Zinc, Arsenic and Trichloroethene
  • improved validation of parameters in Chemical & Risk tabs and related in-browser error reporting
  • fixed some issues in the Graph tab
  • functionality improvements in Risk tab, to improve consistency of risk parameters
  • fixed issues with display of soil/dust ingestion values in Scenario tab
  • fixed issue where Water tab - water consumption factors were uneditable in some cases
  • fixes, improvements and adjustments to the reports, both the summary report and the extended PDF report

The manuals will soon be adjusted to reflect these new features.


S-Risk user agreement updated

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.

TGD and Annex updated

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.

New FAQ entries

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?

S-Risk offline for update

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.

New and updated FAQ entries

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?

Communication issues between browser and server - solution in preparation

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.
