Description

Made available via the Publications (Legal Deposit) Act 2004 (NT).; The objective of the investigation was to test for the presence of PFAS in environmental media, and to provide an indication of the potential for PFAS to have migrated off-site via surface water. This was to assist Defence to meet its objective to facilitate the early identification of potential exposure risks to off-site users of groundwater for the purpose of prioritising any future investigations. This investigation is intended to be a snapshot of the potential off-site presence of PFAS only, and should be regarded as a preceding step to any future preliminary investigations that would be conducted in accordance with the approaches specified by the National Environmental Protection (Assessment of Site Contamination) Measure (ASC NEPM).

Sample History Where samples are submitted/analysed over several days, the last date of extraction and analysis is reported. A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However, no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation). If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.
