  • Webinar: August 2020 Meeting

    Wednesday, 12th August 2020 WA

    Webinar: ACLCA Monthly Meeting – Wednesday 12th August 2020

    Simplified Geology of the Perth Metropolitan Area

    Presented by Frederic Verheyde (Principal and WA Regional Manager), Douglas Partners.

    The objective of the presentation is to summarise in simple terms the geology of the Perth metropolitan area. The presentation begins with a temporal and spatial outline of the geological and tectonic settings at a Western Australian scale, to provide an understanding of major local geological features such as the Darling Fault. It then converges to an overview of the soils encountered at ground surface in the Perth area. This presentation combines recently published breakthroughs regarding the deep geology in WA and the author’s extensive experience with the local superficial geology in Perth. It is a specialised talk presented with simple terms.


    Frederic Verheyde is a geotechnical engineer with about 25 years of experience, the past two decades in Perth and across Western Australia. Frederic is a Fellow of the Institution of Engineers Australia (FIEAust), a Chartered Professional Engineer (CPEng) and a National Registered Engineer (NER) in the areas of Civil and Sub Divisional Geotechnics. He received the Baden Clegg Award from the Australian Geomechanics Society in 2002. He assists academic research (at UWA and Curtin University), in particular regarding the understanding of the behaviour of the main local soils. He has authored and co-authored several peer reviewed technical papers on geotechnical topics and offered numerous technical presentations to the local industry and at international conferences. He is a member of the Western Australian Pavement Group, which is a sub-committee of the Australian Geomechanics Society (Engineers Australia). He is a Company Principal and WA Regional Manager within Douglas Partners, which is an Australian employee-owned consultancy in geotechnics, environment and groundwater.

    Presentation title: Breaking the Pathway of a MTBE Plume in a Complex Geological Setting

    Presentation by: Dave Hellens - Technical Director at AECOM

    An example of the importance of robust conceptual site model (CSM) development at a service station site in the UK which enabled the effective management of an MTBE plume which had reached a public water supply bore. Investigation techniques involved down-hole geophysical techniques, laser induced fluorescence (LIF) and microdensity analysis to aid development of the CSM. Regional steady state and transient groundwater models were developed using MODFLOW to assess the plume behaviour from the site to the public water supply. The CSM development enabled the pathway to be broken with a combination of source treatment and hydraulic containment.

  • DWER News - Contaminated Soils


    The Department of Water and Environmental Regulation (DWER) advises that it no longer requires hard copy submissions (including technical reports) relating to contaminated sites or acid sulfate soils. The Department is intending to develop an online submission portal in the future. In the interim, all submissions relating to contaminated sites or acid sulfate soils should be submitted via email to<>, unless the Department has specifically requested otherwise (such as when a report is required urgently).  Formal submissions, including statutory forms and technical reports should not be emailed to individual officers or to the generic Contaminated Sites email address.

    Statutory forms (including Form 1, Form 2, Form 3 and Form 6) should now be submitted electronically via email to<>. Please ensure that the forms are signed and provided as a PDF file. If you are submitting a Form 1 report of a known or suspected contaminated site and you have a duty to report under section 11 of the Contaminated Sites Act 2003, please ensure that current certificates of title are provided for each land parcel being reported.

    An online payment system is currently being developed for Form 2 'requests for a summary of records in respect of land'. A further update will be provided when the system becomes operational.

    All technical reports should be provided as a text-searchable PDF file. All relevant appendices should be provided within the same PDF file. An exception is for PDF files larger than approximately 300 - 500 pages, when the provision of large appendices (such as laboratory certificates) in separate PDF files is supported to make the electronic document faster to load, read and save.

    For the submission of technical reports, the email should include the following detail:

    *         a clear description of the site, including the legal description, street address and common name;
    *         DWER reference number (eg DMO XXX), if known;
    *         identification and contact details of the report submitter;
    *         purpose for submitting the report, where relevant (e.g. seeking reclassification, planning condition clearance);
    *         for acid sulfate soil reports, specify if the report is being submitted for planning condition clearance, and/or in support of a licence under the Rights in Water and Irrigation Act 1914; and
    *         a list of the technical reports being submitted.

    Providing this information will assist us in processing your submission in a timely manner.

    Where possible, reports and any other documents being submitted should be attached to the email as PDF files. Zipped folders will not be accepted. If the total size of the email, with attachments, exceeds 50 MB, DWER will accept submissions via File Transfer Protocol (FTP). If using FTP, please ensure that:

    *         the access link is not restricted to an individual officer;

    *         login is not required for access; and

    *         a covering letter is included in the submission with the details outlined above.

    Email is the preferred method of submission. However, if you are unable to make a submission via email, please post a hard copy, including a covering letter when relevant (with attachments on an accompanying CD/DVD/USB flash drive) to:

    Senior Manager, Contaminated Sites
    Department of Water and Environmental Regulation
    Locked Bag 33
    Cloisters Square WA 6850

    If posting bulky electronic storage devices, such as USB flash drives, please ensure that the packaging meets the minimum requirements specified by the relevant postal service.

  • DWER News - Per and Poly-fluoroalkyl substances (PFAS) National Environmental


    From: Contaminated Sites []
    Sent: Friday, 18 May 2018 7:24 AM
    Cc: .Br Contaminated Sites <>
    Subject: Email Alert No. 102: Per and Poly-fluoroalkyl substances (PFAS) National Environmental

    The PFAS National Environmental Management Plan PFAS NEMP was released on 16 February 2018 and is available via the Department of Water and Environmental Regulation (DWER) webpage on PFAS Investigations in WA:- The PFAS NEMP provides national guidance on the investigation and management of PFAS contamination and related issues such as waste management. The PFAS NEMP has been developed as an adaptive plan, able to respond to emerging research and knowledge.

    Environmental guideline values provided in the PFAS NEMP replace the screening levels listed in Table 4 of DWER's 'Interim Guideline on the Assessment and Management of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS)' (Department of Environment Regulation, January 2017). When characterising PFAS contamination in WA, practitioners should address at least the analytical suite for PFAS outlined in Table 3.

    Landfill acceptance criteria provided in the PFAS NEMP replace the criteria listed in Table 6 of DWER's Interim Guideline. The PFAS NEMP criteria have been determined based on existing jurisdiction approaches to the derivation of landfill acceptance criteria for a number of standard landfill designs and is consistent with the approach adopted in DWER's Landfill Waste Classification and Waste Definitions 1996 (As amended December 2018)<> [LWCWD].

    DWER has recently updated the LWCWD to include a new waste type (special waste type 3) for soils and other solid wastes impacted by PFAS. Landfill operators licensed under Part V of the Environmental Protection Act 1986, intending to accept PFAS impacted solid wastes, must seek approval under their licence to allow this waste to be accepted. Upon approval the Department will include the relevant waste acceptance criteria in conditions of the licence.
