It is recommended new soil sample results be compared against both \"Trace Elements Level 1\" and \"Level 2\" to assess whether the site is contaminated. \n\nFor a detailed account of the site selection and sampling method employed in this investigation and recommend user guidelines please see Report No. R07/1 \"Background concentrations of selected trace elements in Canterbury soils\"
