There are many methamphetamine (P) contaminated houses, buildings and vehicles throughout New Zealand. Methamphetamine is a problematic contaminant in buildings as contamination is generated from its use and production and can pose a risk to inhabitants’ health.
Forensic & Industrial Science Ltd has been testing for methamphetamine contamination and attending suspected clandestine methamphetamine laboratories since 2004.
Meth Testing Procedure
There are typically a few stages involved in testing for methamphetamine contamination.
The first stage is the screening assessment which determines whether methamphetamine residue is present or absent within a property. Screening assessments are often quick and require fewer samples to be collected, making this type of sampling relatively cheap.
If a screening assessment suggests that there could be at least one surface above the limit of 1.5 µg/100cm2* (micrograms per 100 square centimetres), a detailed assessment will need to be conducted. These assessments require a specified number of samples to be collected in order to accurately assess the extent of the contamination.
If a detailed assessment yields any results above 1.5 µg/100cm2*, decontamination by professional contractors will need to be conducted to bring contamination below the Standard level. After this decontamination is finished, a post-decontamination assessment will need to be undertaken in order to ensure that all surfaces are below 1.5 µg/100cm2*.
*Please note that the level of 1.5 µg/100cm2 is for high-use areas. Limited-use areas use the standard level of 3.8 µg/100cm2.
