CL:AIRE (Contaminated Land In Real Applications) in association with the AGS (Association of Geotechnical & Geoenvironmental Specialists) and the EIC (Environmental Industries Commision), have produced a suite of General Assessment Criteria (GAC’s) for a number of compounds. A total of 35 new GAC’s have been created using the CLEA model (v1.06), 3 metals and 32 organic compounds. Together with the Environment Agency (EA) Soil Guideline Values (SGV’s) and the Chartered Institute of Environmental Health (CIEH) Land Quality Management (LQM) GAC’s, this brings the total of GAC’s available to over 120 potential contaminants.
