1987 Tindal Environmental Contingency Plan

The Department of Defence commissioned an Environmental Management Plan for the operation of RAAF Base Tindal in 1987. This plan consisted of ten task-specific management plans, including the Environmental Contingency Plan, prepared by Kinhill Engineers Pty Ltd.

The Environmental Contingency Plan contemplated the risk and mitigation for 19 different contingency events, including release of fire-fighting foam to the environment. Appendix F to the plan included procedural requirements for foam systems published by the Department of Housing and Construction and information about the foam published by 3M.

The plan was concerned primarily with the collection and proper treatment of foam residues, recognising that the release of large amounts of foam to the environment would cause adverse effects because foam can suffocate living organisms. Based on the scientific understanding of the time, the plan stated that “AFFF and its components are not considered to be dangerous substances, nor are they harmful to the aquatic environment after proper treatment” and “Because of the small proportion of fluorocarbons in AFFF and of the high degree of dilution during treatment and in receiving waters, fluorocarbons are not significant environmental contaminants”.

The plan did not provide any advice regarding the potential for long range environmental transport of PFAS, nor its persistence in the environment or propensity to bioaccumulate. The science on those aspects was not developed at that time.

Defence now understands that the recommended methods of treating fire-fighting foam in sewage treatment plants did not remove PFOS and other persistent chemical residues in the foam.

Investigation Reports



On 3 April 2017, the Commonwealth Department of Health released Health Based Guidance Values for PFAS that were developed by Food Standards Australia New Zealand (FSANZ). All reports issued since that date refer to these guidance values. Any report published prior to this date should be read within the context of the revised FSANZ guidelines.

2017 Katherine Community Survey

This Community Survey has been designed to collect information about water supply and use on properties in the vicinity of RAAF Base Tindal and will inform the Human Health Risk assessment. The Community Survey aims to collect a broader range of information about water and land use than the Water Use Survey that was released earlier in 2017. The Water Use Survey focused on how water was used, the Community Survey looks at additional topics including land and edible produce.

Your participation in this survey is voluntary and you do not have to provide an answer to each question if you choose not to. There is a privacy statement in the survey that explains how the information you provide will be used.

If you need this survey in a language other than English or if you have any questions about the survey, please contact the RAAF Base Tindal Community Hotline on 1800 316 813 or PFAS.RAAFBaseTindal@coffey.com.

The survey can be completed online through SurveyMonkey or on a PDF form.

If you are unalbe to email your survey response please contact the community hotline on 1800 316 813 or PFAS.RAAFBaseTindal@coffey.com to arrange an alternative submission method.
