Townsville Laboratory Service Expands NATA PFAS Accreditation to Soils, Biosolids, and Sediments

Overview

On 21 July 2026, Townsville City Council announced that its Townsville Laboratory Service (TLS) had secured expanded NATA (National Association of Testing Authorities) accreditation to analyse per- and poly-fluoroalkyl substances (PFAS) across a broader range of solid matrices, including soils, biosolids, sediments, sludges, and solid wastes. Building on its existing NATA accreditation for water and wastewater testing, TLS is now the only PFAS-accredited local government laboratory in Australia. The expansion represents a material change in the analytical infrastructure available to environmental practitioners operating across northern Australia.

For environmental consultants, site owners, developers, and regulators working in Queensland and the broader northern Australian region, access to a locally accredited laboratory for PFAS solid-matrix testing has long been a practical constraint. Until now, samples collected from contaminated sites, agricultural land, wastewater treatment facilities, and mining operations had to be transported to commercial laboratories in southern Queensland, New South Wales, Victoria, or Western Australia. This introduced transit time delays, increased shipping costs, and created risks associated with sample preservation and chain of custody. The TLS expansion directly addresses each of these variables.

The timing of this development is significant. The PFAS National Environmental Management Plan version 3.1 (PFAS NEMP 3.1) was released in June 2026, updating the framework that governs PFAS site investigation and risk assessment practice across Australia. Regional testing capability that is fit for purpose under this updated framework is now available in Townsville for the first time, with direct implications for site investigation programme design, remediation project scheduling, and compliance with Queensland’s regulatory obligations for organic waste reuse.

Key details of the TLS PFAS accreditation expansion

The Townsville Laboratory Service’s NATA accreditation for PFAS analysis in solid matrices covers soils, biosolids, sediments, sludges, and solid wastes. NATA accreditation is granted under the requirements of ISO/IEC 17025, the international standard for the competence of testing and calibration laboratories. This standard mandates rigorous quality management, documented method validation, proficiency testing participation, and ongoing internal and external auditing. For contaminated land practitioners, data generated by a NATA-accredited laboratory under ISO/IEC 17025 is defensible in regulatory submissions, site audit processes, and, where required, in expert witness contexts. Accreditation to this standard is a non-negotiable requirement for analytical data relied upon in statutory site assessments across all Australian jurisdictions.

According to Townsville City Council, TLS completed 298,040 analytical tests in the 2024 to 2025 financial year. That throughput indicates the operational capacity to absorb substantial regional sample volumes without the bottlenecks that can affect smaller or newer laboratory operations. For site investigations requiring rapid turnaround, particularly at the Detailed Site Investigation (DSI) stage where decision timelines are compressed by project and regulatory schedules, this capacity is directly relevant. The expansion of PFAS accreditation to solid matrices adds a high-demand analytical suite to an already high-volume facility, which is a meaningful operational advantage for the region.

PFAS analysis of solid matrices such as soils and sediments requires validated extraction procedures before instrumental analysis, typically using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Method performance requirements for PFAS in soils under Australian practice are informed by the PFAS NEMP framework and the associated investigation levels and health screening levels that underpin risk assessment. For the PFAS NEMP 3.1, soil investigation levels apply to individual PFAS compounds and compound groups, with detection limits required to be demonstrably below the relevant investigation level for a given land use scenario. A locally accredited laboratory that can achieve these detection limits removes one of the key technical barriers to executing high-quality site investigations in regional Queensland.

The expansion also has direct relevance to biosolids characterisation. Queensland’s regulatory framework for beneficial reuse of biosolids from wastewater treatment plants operates under the Queensland Government’s End of Waste Code framework. Under this framework, biosolids must be characterised against defined contaminant thresholds before they can be classified as a resource rather than a regulated waste. PFAS has become a central concern in biosolids reuse given the historical use of PFAS-containing firefighting foams and industrial products that enter wastewater streams. Local NATA-accredited testing for PFAS in biosolids and sludges provides a faster and more cost-effective pathway to End of Waste assessments for councils and wastewater operators across northern Queensland.

Australian context: PFAS NEMP 3.1, NATA requirements, and Queensland regulatory obligations

PFAS site investigation and risk assessment practice in Australia is governed primarily by the PFAS NEMP, which is developed and maintained by the heads of Environment Protection Authorities Australia and New Zealand (HEPA). The most current version, PFAS NEMP 3.1, released in June 2026, provides updated guidance on investigation levels, risk assessment methodology, remediation objectives, and laboratory quality requirements. Compliance with the PFAS NEMP is not discretionary in practice. State and territory EPA regulators reference the NEMP in site management orders, remediation action plan (RAP) requirements, and audit instructions. In Queensland, the Department of Environment, Science and Innovation administers contaminated land obligations under the Environmental Protection Act 1994, and PFAS NEMP 3.1 forms part of the technical basis against which site investigation data and remediation proposals are assessed. For practitioners operating in northern Queensland, having access to a locally accredited laboratory whose analytical capability aligns with PFAS NEMP 3.1 requirements reduces both the logistical burden and the technical risk associated with producing data that meets regulatory expectations.
