An official website of the United States government.

Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

2008 External Review of the Concentration x Time (ten Berge) Model

In June, 2008, a new Concentration x Time (ten Berge) model was externally reviewed by experts in modeling and statistics. The intentions of EPA with respect to this model were as follows: 
  • To replicate for use in BMDS the CxT model that Wil ten Berge originally implemented in Visual Basic in the C program language.
  • To develop comprehensive documentation for the model's use in BMDS.

So, the primary charge to the external reviewers was to determine whether these intentions were adequately met.

The reviewers' comments indicated that the first intention was generally met and offered a number of improvements to the model documentation. The ten Berge model included in BMDS takes into account these comments.
