• Background Concentrations of polycyclic aromatic hydrocarbons in Christchurch urban soils - R07/19

  ECan previously commissioned a report to assess the concentrations of trace elements in the major soil groups of the Canterbury Region (Tonkin and Taylor, 2006). This study complements the earlier trace elements study, and seeks to provide information on the current PAH concentrations within the soils of the Christchurch urban area.

• Background Trace Elements in Canterbury Soils Report - R07/1/2

  This report details background concentrations for 10 trace elements in the major Canterbury soil groups. It replaces an earlier report produced in 2005, as further sampling has been conducted to improve the robustness of the data sets.

• Comparison of Soil Guideline Values Used in New Zealand and their Derivations This report outlines all publicly available soil guideline values and their basis of derivitation, developed to assist, or applicable to, the management of contaminated land in New Zealand.

• Contaminated Site Information Management Strategy 2007

  Environment Canterbury has a responsibility to manage and release contaminated site information it collects appropriately, recognising its sensitivity.

  The Contaminated Site Information Management Strategy outlines how Environment Canterbury manages this information in a clear and consistent manner, involving parties with a vested interest in decision-making and management of sites. Assessment of information on contaminated sites helps to ensure that adverse environmental effects arising from land contamination are remedied or mitigated, to an acceptable level of risk.

• Contaminated Land Management Strategy - R07/12

  Environment Canterbury's Contaminated Land Management Strategy sets the organisation's strategic goals for contaminated land management in the region and defines work programmes to meet those goals.

  The strategy details ECan's legislative functions and the policy context for involvement in contaminated land management.

• Contamination of Horticultural Land in Canterbury - A Scoping Study - U06/80

  Environment Canterbury (ECan) has a statutory duty to identify and monitor contaminated land. Horticultural activity is listed on the Ministry for the Environment’s Hazardous Activities and Industries List (HAIL), and is therefore considered to be an activity with a potential to contaminate land. This report, prepared by Pattle Delamore Partners Limited (PDP), is intended to help ECan in scoping to what extent horticultural use may have contaminated land in Canterbury. It does this by providing a broad overview of current and historic horticultural use in Canterbury and, by drawing on local information and studies from elsewhere in New Zealand, provides guidance on the likely chemicals of concern and the possible concentrations within soil of these chemicals.

• Potential for PAH Contamination from Clay Target Debris at Shooting Sites: Review of Literature on Occurrence of Site Contamination from Clay Targets - U06/81

  Questions have been raised about the potential for other contaminants to enter the environment from the other types of debris at shooting sites. In particular debris from clay targets which are known to contain a group of toxic hydrocarbons called polycyclic aromatic hydrocarbons (PAHs). In 1996/97 Environment Canterbury investigations of clay target shooting sites in Canterbury targeted lead contamination from lead shot, the issue of PAH contamination was not included. This report has been commissioned by Environment Canterbury to gather information regarding the potential for PAH contamination of sites.

• Soil Guideline Values for Protection of Groundwater - U06/76

  Environment Canterbury (Ecan) contracted Landcare Research to investigate options for the development of soil guideline values for the protection of groundwater quality. These values will assist in decision making to ascertain whether groundwater contamination is occurring, or might in the future. The work was carried out during 2005-2006.
