ESI supports CIEH with development of statistical analysis software

ESI Ltd has recently supported the Chartered Institute of Environmental Health (CIEH) by developing the ‘CIEH Statistics Calculator’ which is intended to aid the effective dissemination and take-up of the new national guidance  on the use of statistical tests in the assessment of soil contamination data.

The aim of the guidance is to increase the understanding of practitioners of the role that statistics play in quantifying the uncertainty around estimates of average contaminant concentrations. It is the first part of new and revised guidance promised by DEFRA’s ‘Way Forward’ in 2006.

The new guidance sets out step-by-step procedures for conducting statistical tests when assessing soil data in the context of either the land use planning system or Part 2A of the Environmental Protection Act 1990. The intention is that the statistics calculator will help users to conduct these statistical techniques when comparing soil contamination data to a critical concentration as part of wider contaminated land risk assessment projects in both of these legal contexts.

The statistics calculator consists of a series of linked Excel-based, macro-supported worksheets which allow fast and efficient data processing. CIEH is distributing a version of the calculator to local authorities in the UK.  

A commercial version of the calculator is available for purchase and for direct download from the ESI website.  Core functionality of the ESI calculator is identical to that of the CIEH tool, and it has been thoroughly quality assured to ensure that it meets all the tests from the national guidance.
