The national standard
The Australian Clandestine Drug Laboratory Remediation Guidelines (2011) set a residential investigation level of 0.5 µg/100 cm² for methamphetamine. It is a trigger, not a pass mark: results above it call for a detailed assessment and, in most cases, remediation by a specialist contractor followed by validation testing.
The guidelines were written for former clandestine laboratories, but state health departments, insurers and tribunals now apply the same level to contamination from smoking.

Why regional Australia matters
The Australian Criminal Intelligence Commission's National Wastewater Drug Monitoring Program has repeatedly found higher methylamphetamine consumption per capita in regional areas than in the capital cities. Meth contamination is not a big-city problem, and buyers in regional towns have as much reason to test as anyone.

The growing meth problem in Australia
Meth contamination which is an invisible contaminant has no real odour. It is a very real issue for people buying or renting property and can cost thousands of dollars to remediate. Heavy meth use accounts for majority of contamination issues along with meth labs which are still being detected. A regular meth test is the solution.
Tackling the issue with a meth test
Meth residue screening establishes the safety and liability risks within a new property before tenants move in or when a sale transaction is completed. A regular meth test provides a deterrent to meth use and manufacture which can also detect contamination problems early when they are not as costly to fix.

A regular meth test for rental properties is fast becoming best practice in Australia
Regular property inspections to identify maintenance issues are expected by both tenants and landlords these days. Meth residue testing should be part of this regular routine. Apart from the obvious benefits of detecting residue when levels are low enough to make decontamination relatively easy, the chances of meth use on the property decrease substantially, because tenants know the property will have a meth screen regularly.
