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.   

Past activity on land can cause it to become contaminated. The most common causes of contamination in New Zealand is past use of hazardous substances in industry, agriculture and horticulture. Contaminated land needs to be managed or remediated to protect people and the environment.

We have been doing Contaminated Land work for over 15 years and have completed over 200 projects to date including investigating historical contamination of former agricultural and horticultural land, industry, old landfills, timber treatment plants and sportsfields subject to a wide range of potential contaminants – fill material, asbestos, heavy metals, pesticides/herbicides, hydrocarbons, etc.

Our contaminated land team is led by a Certified Environmental Practitioner in Contaminated Land (CEngP-CL), with over 15 years experience in this sector.
