We currently monitor a number of consented cleanfill sites and 'Managed Fill Sites' throughout the Auckland Region, that are allowed to accept low-level contaminated waste. Some are accessible to the public, while others are private.
There are three different types of fill sites:
- Cleanfill – for natural materials such as clay, gravel, rock and soil from areas that are not contaminated with chemicals (this can include small amounts of construction material)
- Managed fill – designed for material with low-grade contamination
- Landfill sites – for heavily contaminated materials and all refuse-type material, such as household and kerbside waste, commercial and building waste, and certain types of hazardous waste (for example, asbestos-containing material).
Disposal of contaminated material is tightly regulated and can only happen on licensed sites.
Resource consent is required for these landfill sites, usually with stringent conditions, and all sites have a council monitoring scheme in place.
