If you are a producer or treater of contaminated soils, you will be required to categorise the soil into Category A, D, B, C or clean fill to determine what management options are available for that material.Waste characterisation involves an assessment of the soil, including site history, to identify which contaminants require analysis to determine the hazard category.To determine the hazard category, contaminated soil must first be considered and excluded from Category A, then considered and excluded from Category B, then considered and excluded from Category C, then considered and excluded from Category D before it can be considered as FILL.Landfill operators will require analytical results to demonstrate that the contaminated soil meets the relevant criteria set out in their licence.Geoaquitards Environmental Provide best cost effective options for disposal or re-use of the material with faster turnaround times when required.
