The CLEA v.1.071 software was released by the Environment Agency on the 4th September 2015. As well as all the features of the previous V1.06, which was based on the human health risk assessment guidance contained in SR2 and SR3, this latest version also incorporates alternative guidance contained in the output from DEFRA research project SP1010. This greatly increases the range of possible input assumptions that can be used to derive assessment criteria using the latest version of the model. Come and join us if you need to know more about what the model can and can't do and what you need to know before you believe the values output by the model!

The course starts with the basics of what the model is and does, explains the different flavours of generic assessment criteria the model can generate and finally allows delegates to explore how the software can accomodate a number of detailed quantitative risk assessment (DQRA) scenarios. The day includes some discussion of recent developments in UK human health risk assessment guidance and generic assessment criteria.

It is assumed delegates have some background in human health risk assessment via work experience or training such as LQM's Human-health risk assessment course

 

This course offers delegates the opportunity to learn more about CLEA v1.071 - how it can and cannot be used. The course will explore the use of the model as a risk assessment tool for the development of generic and site-specific assessment criteria through practical exercises using the software.

Delegates will need to bring their own laptops capable of running Excel with the CLEA 1.071 spreadsheet already loaded and ready to use. Full joining instructions including details of where to download CLEA 1.071 will be sent to each delegate prior to the course.

By the end of the course you should be better able to understand:

  • the scientific basis underpinning the software;
  • the functions and capabilities of CLEA v1.071;
  • how to put data into CLEA v1.071;
  • the software outputs; and
  • the software limitations.

The courses will be of relevance to:

  • Regulatory and local authority staff involved with contaminated land issues
  • Consultants
  • Problem holders and developers needing a more in-depth understanding of contaminated land issues
  • Anyone producing contaminated land reports
  • Anyone reviewing third party reports

The presenter was "knowledgable and engaging.  Answered questions on a 1 to 1 basis"

"[I] had no previous experience using CLEA, only read about it and how it works. Now feel comfortable to work with site specific data!"

"Practical run throughs were a huge benefit.  Making sure each step is fully understood before moving on was great"
