Aims of the Project
The aims of the EIC/AGS/CL:AIRE GAC project were to:
• derive a set of industry agreed contaminant specific parameter values for input to the CLEA
model for a range of commonly encountered contaminants that were not being considered by the
Environment Agency of England and Wales or LQM/CIEH;
• derive a set of industry agreed GAC for those contaminants with sufficient appropriate data to do
so;
Introduction
• present the data and assumptions used to derive the GAC in a fully transparent manner to enable
practitioners to make their own judgements about the suitability of the recommended values for
their specific purposes; and
• provide a spreadsheet of contaminant specific parameter values in electronic format suitable for
input to the CLEA model to facilitate the derivation of site specific assessment criteria for the
researched contaminants.
