Emerging Technology



This event provided an opportunity for ALGA members to learn about new technology and tools available to the industry. It is always great to hear about new tools that help the environment industry to solve complex problems. The following is an overview of what was covered in the session:

Rachael Casson gave an overview of the technology that AECOM have been developing (called DE-FLUORO) which aims to destroy PFAS in water. DE-FLUORO utilizes a proprietary, high durability and low cost electrode that can be fabricated into any shape or size to help meet the needs of the project. So far DE-FLUORO has been shown to successfully treat/destroy measurable PFAS in a range of groundwaters and foam products. The success of this technology has been verified through simultaneous detection of reduced PFAS concentrations and detection of increased fluoride concentrations in solution following treatment. Rachael acknowledged that DE-FLUORO is a useful tool in the remediation of PFAS, but it also has its limitations and is most likely to achieve the best outcomes when coupled with a complementary treatment technology.

Lein Jenkins gave an overview of the technologies that are available for sampling and remediation, and which are widely used in the USA but potentially underutilized in Australia. These technologies included:

Horizontal wells which enable remediation beneath active USTs (or active industrial facilities):

  • A specific drilling mud mixture is used to hold the drill hole open so that a well can be installed.
  • This method can be used in both consolidated and unconsolidated soil types
  • used much more regularly in USA remediation projects compared to Australia.

Passive sampling technologies

  • Geoprobe SP22 water sampling can be used to collect a water grab sample at discreet depths. This tech does not require permitting as there is not well installation. Can be used as a screening phase in initial site investigations to identify the need for more detailed monitoring.
  • Solinst drive point water sampler. Can be driven into the sub-surface profile to obtain a water grab sample for initial site investigations

Well installation technologies

  • Pre-pack well screens. Can be used in heaving sands, guarantees the integrity of installation and filter pack.
  • V-wire well screens (stainless steel or PVC screens). Stainless steel screens can be used at sites where CoPC prevent the use of PVC.

Adam Grant provided an insight into the ALS Compass sampling app that ALS have been developing over the last ~12 months. The technology enables the bulk of the paperwork to be completed prior to field staff leaving the office to reduce the time needed for sample handling (both by the sampler and the laboratory). This new technology aims to reduce the potential for transcription errors and enable the laboratory to meet urgent turn around times. The development of this app marks a turning point in the industry as clients demand solutions to their problems in shorter timeframes and consultants and industry alike have a heightened need for information to be available at very short notice.
