Wednesday Opening - Mananui Ramsden - An Indigenous Way of Life

The Wednesday morning opening peresentation discussed a very topical theme: Living sustainably – an indigenous way of life. 
The indigenous people knew how to live sustainably – we no longer know how to live sustainably. “Mahinga Kai is more than just food, Mahinga Kai is how to harvest sustainably...more.

Te Whakamātai i te Haurehu One - Investigating Soil Gas


This session focused on soil gas investigation. The key theme of the session, and another point mentioned by the keynote address, was that technology is becoming more advanced. It allows more accurate detection of soil gas and reduces conservatism in risk assessments. However, it requires high-quality field work and interpretation by experienced professionals. This was a common point because later presenters showed advances in gas monitoring technology used in their own projects...more
 
Tēpoko - Asbestos
Asbestos dust is toxic to human health as the mineral fibers can become trapped in the body forever through inhalation and cause damage from the inside – which can eventually cause a cancer known as mesothelioma.

One of the common points was that since asbestos is harmful to human health, we need to always keep our knowledge up to date...more

He Mātai Whakatikatika - Case Studies in Remediation
 

The topics from the session covered a wide range of scope and scale, and included: the recoverability of LNAPL from fractured basalt, the remediation of an old gasworks site in central Sydney for a major commercial development, the assessment and management of various contaminants at a zinc galvanising plant, remediation challenges on Mt Ruapehu...more

 

Tautuhi mō te Whakatika - Characterisation for Remediation

• Both ports were major hubs of trade during the operation with industrial activity situated throughout the ports.
• Both sites had a legacy of unknown contamination...more

Te Ture me te Rangatōpū - Legal & Corporate


The session “Legal & Corporate” was primarily a discussion on legal issues that consultants could face during their careers. A range of topics were covered across the legal sector including contractual obligations, legal liability and environmental management plans. The most common point that the session was trying to get across was that it is very easy to face a legal issue if a consultant becomes too complacent...more
 
Te Whakamātai I te Wainuku – Investigating Groundwater
Session Three on Thursday consisted of five talks on the investigation of groundwater. The presentations in this session were varied and covered a range of topics, including: a comparison of using zero-purge and low flow micropurge groundwater sampling methods in PFAS investigations, modelling and assessing contaminant discharges from cemeteries, extrapolating data to overcome data gaps gaps in hydrocarbon plume assessments, using multiple hydrogeological assessments to refine a...more

Te One me te Whakatika Para - Soil & Sediment Remediation


Session Two on Thursday consisted of six talks on soil and sediment remediation. The presentations in this session covered a range of topics, including: the debate of whether the Pupuke Volcanic Field should be a special case when considering the Auckland Council background trace element...more
 
PFAS 1 & 2

Session 1
Total Oxidisable Precursor (TOP) Assay Interlaboratory Study & Review of Method Development - Traditional PFAS testing methods only test a select suite of chemicals that reside under the PFAS/PFOS umbrella and may not accurately represent the total potential PFAS/PFOS that could impact the environment...more

Konganuku Tuturu - Classic Metals


 

This session was made up of several talks.
The first focused on lead, lead toxicology, and issues in NZ. Case study examples were presented. In 2014-16 blood levels were determined in NZ, levels were comparable to the US and Canada. Interventions including home interventions...more

Te Ao Anamata me te Auahatanga - Future Ready & Innovation
The topics in this session differed extensively from each other. They ranged from LNAPL sites to PFAS remediation and groundwater monitoring. However, the common point was that each presentation showcased a new technology or process for dealing with their respective problems. For example, Pedro Balbachevsky showed how remediation electronics systems could...more

Thursday Opening - Nigel Latta – The Psychology of Risk … and Why Humans Generally are Terrible at Every Part of it


Nigel Latta's opening presentation was a fascinating look into the human psyche and the human tendency to value feeling over fact. We have two different systems in our brain, fast thinking and slow thinking. When we assess risk we are fast thinkers, we make decisions based on our gut feeling which causes a bias...more
Pāpori me te Waeture - Social & Regulatory
Numerous landfills across Victoria have issues managing leachate. Poor leachate management can lead to ground pollution and landfill gas problems which short circuiting and the creation of new preferential pathways. The EPA has now set a position to tackle poor leachate management. One solution was to dispose of the leachate to the WW system...more

Bringing Bioavailability into the Fold: Region-Specific Sustainable Land Management


Arsenic is arguably the most common contaminant of concern in New Zealand, and especially in the Waikato Region. Arsenic contamination is often a result of human activities such as sheep dipping, codling moth control in apples or timber treatment and use. But elevated arsenic can also be geogenic – naturally occurring...more

When a CSM Isn't Enough: Dealing With Unexpected Creosote Contamination


The development of a conceptual site model as part of a desk-based investigation was undertaken in accordance with procedures set out in CLMG No1 with additional lines of evidence used to assess the risk to human health including preliminary sampling and analysis of near surface soils. Conclusions reached within the PSI indicated that the risk to human health associated with potential contaminants of concern were low...more

What Do All The Numbers Mean? – A Discussion of Environmental Guidelines Application
 

Per and Poly-fluoroalkyl substances (PFAS) are at the centre of much concern as they have uncertain toxic effects on humans and the environment. In nature, PFAS bioaccumulates and biomagnifies up the food chain. The sensitivity levels of animals are low due to the uncertain and variable impacts of PFAS on different species. For example, it is understood that PFOS bioaccumulates in fish while PFOA does not. While, both PFOS and PFOA can bioaccumulate as they move through the food chain, having, in general, significantly.. more

 

EPA Victoria’s proposed environment law changes


You are likely well aware of EPA Victoria’s proposed environment law changes, but in case you have not, please see below some relevant information in relation to consultation. ALGA will not itself be providing a submission but will rely upon the experience and knowledge contained in the membership to respond. Please feel free to circulate this information to relevant parties.
 
The Victorian Government is currently seeking public comment on proposed regulations that will supports its recently passed Environment Protection Amendment Act 2018. Also on exhibit are proposed Environment Reference Standards that will replace the concept of “beneficial use” currently integrated within the various State Environment Protection Policies.
 
Both the proposed regulations and standards are supported by impact assessments, proposed incorporated documents (e.g. waste classification criteria) and a number of guides to support navigation through the suite of documents.
 
Of particular interest to ALGA members will be:
 

  1. thresholds and circumstances that trigger notification of contaminated land
  2. an administrative process enabling EPA to make determinations about “background levels” of contamination
  3. waste classification as it relates to contaminated soil waste, including a new “Category D” for lower level contaminated soil
  4. land and groundwater sections of the proposed Environment Reference Standard.

 
The public submission period is open until 31 October 2019 and all relevant documents can be found at:
 
https://engage.vic.gov.au/new-environmental-laws/subordinate-legislation
 
(note: some of the documents can be accessed by clicking on “see more” righthand side of the webpage).
