Bioavailability Assessments

  • Bioavailability is the amount of a contaminant that is absorbed from soil into the human digestive system

  • Current guideline values assume 100% bioavailability - testing is now available for lead and arsenic that may show significantly less is bioavailable, resulting in less remediation

  • We can provide advice on the likelihood of a bioavailability assessment making your project more viable,​​ along with all site work and reporting to support a consent application


Lead Paint Testing

Many older houses have paint on them that are likely to contain lead. Lead paints were still used routinely on domestic housing in New Zealand up until around 1965. Even up to around 1980 some paint products could still have lead in them.

Malloch Environmental Ltd can provide full house paint testing using our portable XRF, and advice on how to safely manage any lead paints present.
