Contaminated Land

Land is a valuable resource, the condition of which can be significantly affected by its current and historic uses. The presence of contaminated soil and groundwater on a site can have an adverse effect on human health and the wider environment, as well as creating potential liabilities for the owner. Envirolink can help solve these problems.

National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health (2011)

With the introduction of the National Environmental Standard for Assessing and Managing Contaminants in Soil to Protect Human Health (2011) the investigation of potentially contaminated land is a requirement if current or historical land activities are included on the Hazardous Industries and Activities List (HAIL). Contaminated land advice is generally sought:

  • When potential purchasers/investors wish to gain reassurance that the land they are buying is not contaminated and that they will not incur large scale remediation costs;
  • When reference data is required to prove the condition of the land prior to leasing for industrial, commercial or other uses; and
  • When landowners/developers propose to change the current land use to a more sensitive one e.g. industrial or commercial use to residential use.

  • Former timber treatment plants;
  • Boat cleaning and maintenance yards;
  • Buried refuse sites;
