Contaminated Land

“Contaminated land” is land that contains hazardous substances (contaminants) in soil at elevated levels that can have significant adverse effects on human health and the environment.   

Contaminated land needs to be managed or remediated to protect people and the environment. We have been doing Contaminated Land work for over 10 years and have completed over 200 projects to date including investigating historical contamination of former agricultural and horticultural land, industry, old landfills and sportsfields subject to a wide range of potential contaminants – fill material, asbestos, heavy metals, pesticides/herbicides, hydrocarbons, etc.

We cover all facets of contaminated land work, including the following:

  • Preliminary site investigations (PSI)- desktop studies, visual appraisal, reporting
  • Detailed site investigations  (DSI) – PSI + soil/water sampling, laboratory analyses and XRF sampling, reporting
  • Risk assessments
  • Resource consenting – NESCS, District and Regional Plans
  • Remedial Action Plans, Management and Monitoring Plans
  • Supervision of remedial works, site validation and reporting
  • Peer review and preparation of expert evidence
