Name: Trace Elements Level 2

Display Field: SOILGROUP

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer gives the results of a detailed investigation into the background concentrations of selected trace elements in Canterbury's major soil groups from samples taken between 28/2/2006 and 16/3/2006. Canterbury soil groups identified by the Land Resource Inventory (LRI) and Canterbury Soils (CS) datasets were used in this investigation and are retained in this layer. A total of 90 sample sites were distributed across these soil groups; 17 in the Christchurch urban area and 73 through-out the rest of Canterbury. From these samples concentrations of; Arsenic, Boron, Cadmium, Chromium, Copper, Lead, Manganese, Mercury, Nickel, and Zinc were measured in mg/kg. Level 2 gives the maximum concentration values of the above trace elements measured in each soil group plus half the interquartile range (buffer). 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. For 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" prepared for Environment Canterbury by Tonkin and Taylor Ltd, July 2006.
