About this workshop:

“Risk-Based Corrective Action” or “RBCA” guidance and corresponding, pre-approved screening levels developed in the 1990s allowed for rapid identification of potential environmental concerns at contaminated sites and initial design of remedial actions. Delays in project completion, cost overruns and the discovery of contamination at sites that had been previously declared “clean” have persisted, however. Valuable properties are sometimes abandoned due to the lack of a clear endpoint. “Laboratory error” is often used as the scapegoat. Closer inspection reveals the majority of the blame to be associated with in the collection and use of “discrete” or “grab” samples of soil, sediment and other environmental media to characterize sites, rather than methods more directly tied to the assessment of risk.

This workshop will review the origin of early regulatory guidance for the use of “discrete” or “grab”  samples to characterize environmental contamination and the inherent limitations of the resulting data. Circumstances behind the failure to heed early warnings by USEPA staff and other government and private experts will be explored. “Risk-based” sampling methods long used in the equally sampling intensive mining and agriculture industries will then be introduced as a solution to this dilemma. The Systematic Planning process presented directly ties methods used to collect, process and test samples with the assessment of risk and optimization of remedial actions. Upfront specification of “Investigation Questions” coupled with designation of risk- or remediation-based “Designation Units” and the collection of “Multi Increment” samples ensures that the resulting data will be both technically defensible and reliable for final decision making.

The approaches described will likely seem common sensical to new professionals in the environmental industry. The change in mindset and questions regarding the reliability of “traditional” types of sample data can be challenging for seasoned practitioners, however, as it was for the presenters of this workshop. Concepts such as the designation of specific Decision Unit areas for collection of soil samples will seem familiar, however, as will questions regarding the representativeness of a random, grab sample of soil from a single point in terms of the immediately surrounding soil. The workshop will end with a discussion of “next steps” for implementation of Risk-Based Investigation methods in Australia and topics for future, more focused workshops on specific topics. The risk-based investigation methods introduced can require more planning and effort at the beginning of a project but will help ensure that projects are completed on time and on budget and with a high degree of confidence in the results


WORKSHOP 6:  ASBestos-IN-Soil (ASBINS) Masterclass
Sunday 15 September 2024
Location: City Room 4, Adelaide Convention Centre
1.30pm - 5.00pm

Registration at 1:00pm for 1:30pm Start
Presenters: Ross McFarland, Girish Choppala, Chris Kennedy, Pierina Otness

About this workshop:

Asbestos is a contaminant that differs from most others. In particular, its toxicology is such that it primarily affects humans rather than being a risk to the environment. For humans, the main exposure pathway is through inhalation.  Inhalation of asbestos fibres can produce a range of lung-associated diseases, including cancers, sometimes resulting from only low levels of exposure.

ASBestos-IN-Soil (ASBINS) is also a unique kind of contamination.  It usually occurs discretely in an impacted area and its degradation over time is slow with very low flux rates.

ASBINS can migrate through physical disturbance and this is when its dangerous fibres can be released.

While asbestos in air measurement has been undertaken by occupational hygienists for more than fifty years (since 1969) the measurement of ASBINS has only made significant international progress since 2008 (by Frank Swartjes and Peter Tromp)and in Australia since 2009 when the Western Australian Department of Health published its first edition of the “Guidelines for the Assessment, Remediation and Management of Asbestos-Contaminated Sites in Western Australia”, subsequently revised in 2021.

This workshop will summarise the basis of the ASBINS assessment, discuss why the different approach was necessary and present scientifically-defensible methods for derivation of site-specific threshold ASBINS values.  Recent developments in ASBINS assessment and management will also be presented by industry practitioners and a case study will be discussed.
