Managing contaminated land, hazardous substances and waste

Last updated: 01 November 2023
Reporting frequency: Quarterly
Portfolio: Climate change and community resilience

We are identifying and managing contaminated land, hazardous substances and waste so that risks to humans and the environment can be properly managed.

We are required under the Resource Management Act 1991 to manage the discharge of contaminants to the environment and to investigate land for the purpose of identifying and monitoring contaminated land.

We also aim to support new and better ways of managing waste and hazardous substances across the region.

This work includes:

  • Contaminated land identification and monitoring
  • Contaminated site response
  • Delivery of waste reduction projects in collaboration with district and city councils in the region.

How are we tracking on our Levels of Service?

Level of Service 24: Identify and monitor contaminated land.

To achieve this Level of Service we will:

  • 24.1: Identify potentially high-risk contaminated sites in the Canterbury region.
  • 24.2: Produce a priority list of closed landfill sites threatened by the impacts of climate change.

How are we doing: An internal project team has been established to develop a risk-based approach to identify potentially high-risk contaminated sites in Canterbury. Next steps include engaging an external consultancy to assist with the development of the risk model, developing a proof of concept using a small data set, testing the model and receiving feedback, and finalising the model.

The team is working closely with select landowners on landfill related issues. Staff will continue proactive site assessments and landowner communication. 

On track
Level of Service 25: Partner with the Canterbury region’s city and district councils to progress waste minimisation.

To achieve this Level of Service we will support the Canterbury Joint Waste Committee to develop a regional waste data project.

How are we doing: We continue to advocate for the development of a Regional Waste Strategy, including a focus on regional data consistency. A meeting with Christchurch City Council’s (CCC’s) waste manager has confirmed interest in the initiative. We will continue to engage with the district councils through the Canterbury Joint Waste Committee and with CCC’s waste manager.

Illegal dumping is rife across the region and it’s not just the inorganic items that are putting our flood protection, biodiversity and water health at risk.
