Detailed Screening

Detailed assessments are designed to determine the extent of methamphetamine contamination within a property. These assessments are conducted when a property is known to be contaminated with methamphetamine, either by a positive a screening assessment or by other strong evidence such as the presence of drug paraphernalia or police involvement.

Sampling Methodology

Detailed assessments involve a site inspector taking at least one discrete sample from each “high use” area in accordance with the New Zealand Standard 8510 Testing and decontamination of methamphetamine-contaminated properties. By taking individual samples in every area of the building, accurate decontamination advice can be prepared. This is important as different concentrations of methamphetamine require different decontamination actions. For example, lower levels of methamphetamine may be able to be cleaned while higher concentrations may require full removal of the surface to satisfy criteria set by the NZS 8510.

If a sample yields a concentration above the limit set by the NZS 8510, we will provide decontamination recommendations to reduce methamphetamine concentrations to below the NZS 8510 levels in our report. Forensic & Industrial Science Ltd does not perform decontamination and we have a strict policy of not recommending decontamination contractors in order to stay fully independent.

Post-decontamination Assessments

Post-decontamination Assessments

Once a property has been decontaminated, a post-decontamination assessment is performed to ensure methamphetamine contamination has been reduced to below the decontamination levels set in NZS 8510. Prior to attending the site, a site inspector will get in touch and will provide a sampling plan in accordance with NZS 8510. Once the sampling plan is agreed upon the site inspector will conduct the post-decontamination site inspection where they will review all of the decontamination actions undertaken and collect surface samples for analysis in line with the NZS 8510.

Quality Assurance/Quality Control

Forensic & Industrial Science Ltd performs detailed and post-decontamination assessments in line with the NZS 8510 Testing and decontamination of methamphetamine-contaminated properties and are accredited by International Accreditation New Zealand (IANZ) for this work. All of our inspectors hold a university qualifications in Forensic Science and/or Chemistry and are trained in locating signs of clandestine methamphetamine manufacture while on site.
