PFAS
Fire training grounds, airports, defence land, landfill leachate, spent carbon and resin.
PFAS arrived in New Zealand mostly in firefighting foam. It is in the soil at fire training grounds, airports and defence land, in landfill leachate, and in the spent carbon and resin that water treatment uses to catch it. Ministry for the Environment guidance covers investigation and response, and sites are being found faster than pathways are being built to deal with them.

Containment, landfill or export. Impacted soil is capped or sent to a Class 1 landfill under the waste disposal levy, where the PFAS joins the leachate. Spent media and foam stockpiles have been exported for offshore treatment. Water is dosed through more carbon and resin, which then becomes the next stream to deal with.
PFAS is separated and concentrated into a small, defined volume. The soil or water is verified against your criteria. Separation and concentration is the whole of what we claim: the concentrate leaves with its own chain of custody for specialist downstream handling, and the clean fraction comes back with an independent laboratory report.
